Answer:
The correct answer is - hypotonic solution.
Explanation:
A hypotonic solution is a solution with low osmotic pressure than another or adjacent solution. In biology hypotonic solution that has low solute concentration and more solven or water than the another solution.
In such solution the solute has less or decreased solute and the movement of the water will be inwards the cell which cause cell swelling and breakage or burst. In the given question the mistake in preparing culture media creating hypotonic as it swells and burst.
Thus, the correct answer is - hypotonic solution.
Which two statements are true about dehydration synthesis?
A. An OH group from one component and an H atom from the other form a water molecule.
B. Polymers are broken down into shorter chains or monomers.
C. Monomers or polymers are joined to form longer chains.
D. A molecule of water is consumed.
E. Its atoms are added to a bond, putting an OH group on one end and a hydrogen atom on the other.
Answer:
A. An OH group from one component and an H atom from the other form a water molecule.
C. Monomers or polymers are joined to form longer chains.
Explanation:
Dehydration reactions are the ones in which a water molecule is released during the formation of a covalent bond. Since these are "synthesis" reactions, complex molecules are formed from the simpler monomers. Therefore, dehydration synthesis refers to the reactions that form complex polymers by joining the monomers together.
For example, when a peptide bond is formed between two amino acids, OH group from one amino acid and "H" from the other amino acid join together and are released in the form of "H2O". A covalent bond is formed between the two amino acids. many amino acids are joined together in this way to form long polypeptide chains.
Dehydration synthesis involves the formation of longer chains by joining monomers or polymers together, accompanied by the removal of a water molecule.
Explanation:The two statements that are true about dehydration synthesis are:
An OH group from one component and an H atom from the other form a water molecule. During dehydration synthesis, a water molecule is removed as two monomers or polymers join together to form a longer chain. The OH group from one molecule combines with the H atom from the other to form water.A molecule of water is consumed. Dehydration synthesis involves the loss of water, meaning that a molecule of water is used up during the process of joining monomers or polymers together.Learn more about Dehydration synthesis here:https://brainly.com/question/31871321

In Drosophila melanogaster, ebony body color is determined by the e allele. The e' allele produces the wild type honey-colored body. In heterozygotes for the two alleles, a dark marking called the trident can be seen on the thorax, but otherwise, the body is honey-colored. The e' allele is thus considered to be incompletely dominant to the eallele. When female e' e' flies are crossed to male e' eflies, what is the probability that progeny will have the trident marking? Animals with the marking mate among themselves. Of 300 progeny, how many would be expected to have a trident, how many would have ebony bodies, and how many would have honey-colored bodies?
Answer:
a) 50% or 0.5
b) trident marking = 150
honey colour = 75
ebony colour = 75
Explanation:
Given,
e'e' = wild type honey colour
e'e = honey colour with trident
ee = ebony colour
a) e'e' X e'e :
e' e'
e' e'e' e'e'
e e'e e'e
50 % of the progeny has e'e genotype so 50% of the progeny will have trident marking.
b) e'e X e'e :
e' e
e' e'e' e'e
e e'e ee
50 % of the progeny has e'e genotype so 50% of the progeny will have trident marking = 300 * 0.5 = 150
25% of the progeny has e'e' genotype so 25% of the progeny will have honey colour = 300*0.25 = 75
25% of the progeny has ee genotype so 25% of the progeny will have ebony colour = 300*0.25 = 75
Final answer:
In a cross between female e' e' and male e' e Drosophila melanogaster flies, 50% of the progeny (150 out of 300) are expected to have the trident marking, showing incomplete dominance of the e' allele over the e allele. Additionally, 75 would have honey-colored bodies, and another 75 would display ebony bodies.
Explanation:
The question about Drosophila melanogaster, specifically regarding the inheritance of the ebony body color and the trident marking, falls under genetics, a branch of biology. When female e' e' flies are crossed with male e' e flies, the offspring can have either e' e', e' e, or e e genotypes. The e' allele is incompletely dominant over the e allele, meaning that heterozygotes (e' e) will have the distinct trident marking on the thorax with a honey-colored body. Thus, when these heterozygotes mate among themselves, the expected genotypic ratio in their progeny would be 1:2:1 (e' e':e' e:e e).
Given that information, for 300 progeny:
25% (75) would be expected to have a honey-colored body (e' e' genotype), with no trident marking.50% (150) would have the trident marking (e' e genotype), showing incomplete dominance.25% (75) would display an ebony body (e e genotype), as this trait is recessive.

Answer: ... it stores its genetic information as RNA and not as DNA and can synthesize ...
Explanation:
In contrast with other viruses, HIV can't be got rid of completely from the human body , even with treatment.
So like stated above, the characteristic of the human immunodeficiency virus (HIV) that makes it different from other RNA viruses is that it stores its genetic information as RNA and not as DNA and can synthesize DNA from an RNA template it carries to override it hosts DNA.
So once one get HIV, such have it for life. HIV attacks the body's CD4 cells (T cells) that wall of the immune system that specifically help the immune system fight off infections.
The mechanism of the HIV storing its genetic information as RNA rather than as DNA , it replication and infection pattern has made it standout to become a global treat.

A. All species are connected to one another in a "family tree."
B. All species are linked to one another by common ancestry.
C. Species are constant and unchanging in their present forms.
D. Species are the product of special creation by God and not subject to natural laws.
E. Species descend from other species just as naturally as children come from parent.
Answer: A. All species are connected to one another in a "family tree."
B. All species are linked to one another by common ancestry.
E. Species descend from other species just as naturally as children come from parents.
Explanation:Charles Darwin is an English Scientist, who is also an Naturalist, Geologist. He is famous for the work he published in the year 1859 where he stated the law of evolution through which most evolutionary works in the field of science has been derived.
He stated in his Theory of Evolution that all species of living organisms evolve through the natural selection inherited variations that helps the living organism to compete, survive, and reproduce favorably. To Dawning these variations may be small and insignificant. This theory tend to see living organisms as having a common ancestry, United in the form of a family tree etc.
______________ are agents (e.g., chemicals, viruses) that can reach the embryo or fetus and cause it harm.
Answer:
These agents are known as teratogens.
Explanation:
Teratogens impair or cause abnormal development and growth of the embryos or fetuses exposed to them. During prenatal development, the embryonic stage is the most susceptible to teratogens because at this time there is formation of major organs and limb buds. Birth defects are a common sign of such exposure.

You are given a 1 liter bacterial culture in exponential stage of growth. The generation time of the bacteria is known to be 30 minutes. When given to you the concentration of bacteria is 2x10^3 bacteria per ml (milliliter). Assuming space and nutrients are unlimited during your experiments. How many total bacteria would you after five hours of growth?
a. 2,048,000,000 bacteria
b. 4,096,000 bacteria
c. 1,024,000 bacteria
d. None of the answers given
e. 2,048,000 bacteria
f. 1,024,000,000 bacteria
Answer:
Option-A
Explanation:
A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.
The bacterial cell grows by the exponential function that is by [tex]2^{number of generation}[/tex] x initial population of bacteria.
In the given question,
Initial population
the initial population of bacteria - 2x 10³ per ml
So per liter, the bacterial population will be 2 x 10 ⁶
Generation time
1 generation time of bacteria is 30 min.
so 5 hours will have- [tex]\frac{300}{30}[/tex]= 10 generations
New bacterial population
Using formula [tex]2^{number of generation}[/tex] x initial population of bacteria
[tex]2^{10}[/tex] x (2 x 10⁶)
= 1048 x (2 x 10⁶)
2048 x 10⁶
Thus, Option-A is the correct answer.
After five hours of growth, the total number of bacteria would be A. 2,048,000,000.
To determine the total number of bacteria after five hours of growth, we need to understand the concept of exponential growth in bacteria and apply the relevant calculations step by step.
Step 1: Understand the Initial Conditions
You started with a concentration of bacteria: 2 x 10^3 bacteria/ml.
Since you have 1 liter of culture, we convert liters to milliliters:
1 liter = 1000 ml.
Therefore, the total number of bacteria initially is:
Initial number of bacteria = 2 x 10³, bacteria/ml x 1000 ml
= 2 x 10⁶ bacteria
Step 2: Determine the Doubling Time
The generation (doubling) time is given as 30 minutes.
To find out how many generations occur in five hours, first convert hours to minutes: 5 hours = 300 minutes.
The number of generations, [tex]n[/tex], can be calculated as:
[tex]n = \frac{\text{Total time}}{\text{Generation time}} = \frac{300 \, \text{minutes}}{30 \, \text{minutes/generation}} = 10 \text{ generations}[/tex]
Step 3: Calculate the Total Number of Bacteria
The formula for exponential growth is:
Final number of bacteria = Initial number x 2ⁿ
Substituting in the numbers:
Final number of bacteria = 2 x 10⁶ x 2¹⁰
We know that [tex]2^{10} = 1024[/tex], so:
Final number of bacteria = 2 x 10⁶ x 1024
= 2.048 x 10⁹
= 2,048,000,000 bacteria
If one builds a canal linking a predator-rich pond to a predator-poor pond, then what type of selection should subsequently be most expected among the mosquitofish in the original predator-rich pond, and what type should be most expected among the mosquitofish in the formerly predator-poor pond?
Answer:
The answer is directional selection.
Explanation:
Selection types can be given as stabilizing, disruptive and directional selection and the example given in the question is an example of directional selection.
In directional selection, the phenotypes of the species take role in determining their chances of survival and in this situation the one will have the advantage over the other species in terms of survival because they were initially living in different conditions therefore they will experience directional selection but in opposite directions meaning one will have a positive impact and the other negative.
I hope this answer helps.
Building a canal between a predator-rich and predator-poor pond will likely cause directional selection among mosquitofish in both ponds, favoring traits that help avoid predation.
Explanation:When a canal is built that links a predator-rich pond to a predator-poor pond, it creates an opportunity for predators and prey species to move between these two environments. For the mosquitofish in the original predator-rich pond, the introduction of this new link may lead to directional selection. This type of selection will favor the mosquitofish traits that are better at evading predators, perhaps leading to faster or more agile fish that can escape predation. Meanwhile, in the formerly predator-poor pond, the mosquitofish there may soon experience an increase in predation pressure due to the movement of predators through the canal.
The result could be a shift in mosquitofish populations towards traits that improve survival in the presence of predators, such as more drab coloration or behaviors that make them less noticeable. This change aligns with findings from studies by John Endler and others, suggesting that predation pressure can significantly alter the physical and behavioral characteristics of prey species. Both disruptive selection and assortative mating may also come into play, as different traits become advantageous in the new shared environment of the canal-linked ponds.
Describe the manner in which you would determine how long ago two species of bacteria diverged from one another.
Answer:
One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.
Explanation:
Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.What organ system is often the first to show signs and symptoms in multiple organ dysfunction syndrome (MODS)?

Nicole and Camille are synchronized swimmers for their college swim team. They often work long hours to ensure the movements in their routine are perfectly timed. What part of their brains must Camille and Nicole rely on most?
Answer: Camille and Nicole must rely on the cerebrum
Explanation:
Since Camille and Nicole are synchronized swimmers, there is no doubt that they will require the following:
- movement of legs and arms, which are voluntary actions controlled by the cerebrum
- proper reasoning and judgment for perfectly timed dives, which are controlled by the seat of intelligence - the cerebrum
- long hours of practice to perfect learning, and learning of information is also controlled by the cerebrum.
Thus, both Camille and Nicole must rely on the parts of the brain called cerebrum

Aerobic literally means "without oxygen." Aerobic activity is high-intensity activity. Group of answer choices True False
Answer: False
Explanation:
Anaerobic means the absence of oxygen while aerobic means the present of oxygen. Anaerobic exercise do not utilize oxygen as energy source, it uses energy from the break down of glucose in the muscles. This exercise is of short length, fast and of high-intensity. A lot of energy is released within a small period of time.
Biologically anaerobic exercise must be fueled using glucose through a process called glycolysis in the muscles cells.
The break down of glucose during high-intensity training without oxygen, producing energy quickly. Because it occurs in the absence of oxygen this process also produces lactate, which is the metabolic fate if glucose in anaerobic condition.
High concentration of lactate is the reason why your muscles get so tired after the energy burst.
During the Carboniferous period, forests consisting mainly of produced vast quantities of organic matter, which was buried and later became coal. A) giant woody mosses C) ferns and other seedless plants B) gymnosperms D) angiosperms
Answer:
Option (C)
Explanation:
The Carboniferous period is one of the important periods of the Paleozoic era, which started about 360 million years back and ended by about 300 million years back.
The Carboniferous period is characterized by the presence of swampy forests, where the dominant plants were the ferns, club mosses, some primitive conifers and other types of seedless plants.
These plants were abundantly present covering a large portion and comprised of vast quantities of organic matter, which were later buried and transformed into the Carboniferous coal.
Thus, the correct answer is option (C).
Final answer:
During the Carboniferous period, forests of ferns and other seedless vascular plants like club mosses and horsetails contributed to the formation of coal deposits.
Explanation:
During the Carboniferous period, forests consisting mainly of ferns and other seedless plants produced vast quantities of organic matter, which was buried and later became coal. Vast swamp forests of club mosses and horsetails, some reaching heights of more than 30 meters, were prevalent. These plants had evolved vascular tissues, well-defined leaves, and root systems, which allowed them to grow large and become major contributors to the coal deposits that characterize the Carboniferous period. As seedless vascular plants, the sporophyte generation became dominant in these species, and the massive amounts of carbon they deposited eventually turned into coal.
What does Socrates do when he finds a man with a reputation for wisdom? What three classes of people does Socrates question? How does he find all three lacking?
Answer:
Socrates will always question any man with a reputation for wisdom. He wanted he/she to examine his/her live and become aware of their own ignorance rather than thinking that they know things when actually they know nothing.
The three classes of people Socrates questioned were the politicians, Poets and craftsmen.
He found all three lacking in the real wisdom (Higher Things or Human Excellence) as they only possessed human wisdom in their respective trades.
Final answer:
Socrates questions individuals reputed for their wisdom, including politicians, poets, and artisans, to understand what true wisdom is, only to find that their supposed wisdom falls short. He concludes that real wisdom is realizing one's ignorance.
Explanation:
When Socrates finds a man with a reputation for wisdom, he questions him to understand what true wisdom is and whether that individual truly possesses it. He broadly categorizes people he questions into three groups: leaders of Athenian society (politicians), poets, and artisans (craftsmen). Socrates discovers that each group, despite their reputed wisdom, is lacking. Politicians did not truly understand the policies they endorsed, poets could not explain the meaning of their works beyond the surface level, and artisans, while skilled in their crafts, mistakenly believed their technical expertise extended to other areas of knowledge as well. This exploration led to Socrates' realization that true wisdom comes from acknowledging one's ignorance, a revelation that aligns with the Oracle at Delphi's pronouncement of him as the wisest among men for his recognition that human wisdom has little value.
In familial hypercholesterolemia, individuals homozygous for the allele causing the disorder completely lack receptors on liver cells that take up cholesterol from the blood stream. Heterozygotes have one-half the number of receptors while individuals homozygous for the normal allele are phenotypically normal. This is an example of:
Answer:
The correct answer is - incomplete dominance.
Explanation:
A inheritance pattern that is characterized by pattern in which the one allele is not completely dominant over the its recessive variant of the allele and due to its incomplete dominance a third phenotype expressed over, termed as the incomplete dominance.
In the case of the familial hypercholesterlemia, it is genetic disorder in which the individual lacks the receptors on liver cells remove cholesterol from the blood. This condition occur in the homozygous allele case. In normal people have receptors normal while in heterozygous condition individual have half of the total receptors.
Thus, it is the case of incomplete dominance.

After suffering an accidental brain injury, Kira has difficulty walking in a smooth and coordinated manner. She has probably suffered damage to her a. corpus callosum. b. hypothalamus. c. amygdala d. cerebellum.
Answer:
d. cerebellum.
Explanation:
The cerebellum, which is part of the hindbrain, is a small structure made of a covering of white cortex found under the hemispheres of the cerebral cortex. The cerebellum plays a major role in the control and coordination of all physical movements such as balance, control, etc, that has to deal with smooth and balanced activities of the muscle.
A damage to the cerebellum would most likely lead to impaired motor coordination, staggering, inability to judge distance or when to stop.
The cerebellum, located at the base of the brain, is pivotal for maintaining balance and coordinating voluntary movements. Damage to this area can result in a lack of muscle coordination during voluntary movements, therefore, Kira's issue with smooth walking and coordinated movements suggest damage to her cerebellum.
Explanation:After suffering an accidental brain injury, it seems that Kira is having trouble with coordinated movements and smooth walking. This suggests damage to her cerebellum. The cerebellum, located at the base of the brain, is pivotal in maintaining balance and coordinating voluntary movements. Damage to this area can result in a condition known as ataxia, characterized by lack of muscle coordination during voluntary movements such as walking or picking up objects. Neither the corpus callosum, amygdala, nor hypothalamus would produce these specific symptoms when damaged.

Answer: True
Explanation:
Tuberculosis(TB) is most common in developing countries where many people live in absolute poverty, than in developed countries.
In underdeveloped and developing countries people lack proper education on the spread of tuberculosis, they live and work in poorly ventilated and overcrowded conditions, which provide ideal conditions for TB bacteria to spread.
In developing countries where people have limited access to healthcare system, people with HIV who are more susceptible to TB, lack proper healthcare suffer from malnutrition and can't build a resistance to the disease. In this conditions TB is bound to spread.
Developed countries have largely controlled TB by improving the life of it citizens, provision of healthcare, education etc
Which of the following statements is/are incorrect? 1. The nervous and endocrine systems act together to help to maintain homeostasis. 2. The nervous system acts through nerve impulses while the endocrine system uses hormones to control body activities. 3. The endocrine uses neurotransmitters for communication while the nervous system communicates using hormones. 4. Neurotransmitters and hormones may both exert effects by binding to target cell receptors. 5. The endocrine system responds slowly while the nervous system responds quickly.
Answer:
The incorrect statement is statement 3:
The endocrine uses neurotransmitters for communication while the nervous system communicates using hormones.
Explanation:
To explain this, let us look briefly at what the endocrine and nervous systems are.
Endocrine System
:
To explain this, let us look briefly at what the endocrine and nervous systems are.
Endocrine System: The endocrine system made up of an aggregate of glands that produce hormones (chemical messengers) and the effect of the hormones are seen on a target site. The endocrine gland is responsible for the regulation of several activities in the body including metabolism, function of tissues, growth and development, sexual function, mood etc. Every time endocrine system is mentioned, the first thing that should come to your mind is hormones and chemicals. Hormones are chemical signals that are released directly into the blood stream causing regulation on a site called the target site.
Nervous System: The nervous system in an organism is responsible for coordination and it makes use of electric signals and neurotransmitters transmitted along nerve cells. At the point where two nerve cells meet (synaptic cleft) the electrical signals that have travelled through the length of the nerve cell called axon, are briefly converted to chemical signals which are called neurotransmitters. Neurotransmitters are used as messengers either between two neurons or between a neuron and a muscle. The effect of a neurotransmitter can be inhibitory, excitatory or modulatory.
All the other statements are correct because:
1. The nervous and endocrine systems act together to help to maintain homeostasis, and homeostasis is the regulating of the internal enviroment of an organism in order to maintain equilibrum.
2. The nervous system acts through nerve impulses while the endocrine system uses hormones to control body activities as I explained above.
4. Neurotransmitters and hormones may both exert effects by binding to target cell receptors. Binding to receptors by the neurotransmitters and hormones are the mechanisms of interaction with the target sites
5. The endocrine system responds slowly while the nervous system responds quickly. The nervous system use electric signals which travel very fast relative to hormones, which are secreted into the blood stream and travel to the target site through this means.
I suggest you read more on body systems to know their various compositions and functions so that you can answer the question yourself next time.
Final answer:
Statement 3 is incorrect because it states that the endocrine system uses neurotransmitters for communication, when in fact, it uses hormones. Both the nervous and endocrine systems are crucial in maintaining homeostasis and use chemical signals to communicate, with neurotransmitters being specific to the nervous system.
Explanation:
The question relates to the functions of the endocrine and nervous systems. To identify the incorrect statements, we must understand how these two systems operate and communicate within the body.
The first statement is correct; both systems do indeed play a role in maintaining homeostasis. The second statement is also correct; the nervous system communicates via nerve impulses, while the endocrine system uses hormones. The fourth statement is true as well; neurotransmitters and hormones exert their effects by binding to specific receptors on their target cells.
The fifth statement correctly highlights that the endocrine system typically responds more slowly compared to the instant reaction of the nervous system. However, the third statement is incorrect because the endocrine system uses hormones for communication, not neurotransmitters, which are used by the nervous system.

When the neuron is at rest, what is primarily responsible for moving potassium ions OUT of the cell?
When the neuron is at rest, what is primarily responsible for moving potassium ions OUT of the cell?
a concentration gradient
an electrical gradient
both a concentration gradient and an electrical gradient
the sodium-potassium pump
Answer:
a concentration gradient
Explanation:
At rest, the sodium-potassium pumps pump the two potassium ions into the cell for three Na ions moved out of the cell. This creates a higher potassium concentration gradient inside the cell. This concentration gradient moves the K+ out of the cell. Movement of positively charged K+ out of the cells make the inside of the membrane negative with respect to the outside. This is how the negative resting potential is maintained when neurons are nor firing the action potential.
When the neuron is at rest, the primarily responsible for moving potassium ions OUT of the cell - concentration gradient
Neuron Is the main component of nervous tissue in the nervous system as it sends signals by electro-chemical signaling.A neuron at rest is negatively charged within the cell is created by the cell membrane being more permeable to potassium ion movement than sodium ion movement.At rest, there is a high concentration of potassium ions (K+) inside the cell compared to the extracellular fluid due to a net movement with the concentration gradient.A High number of potassium ions reside inside the cell, a chemical gradient occurs and pushes potassium out of the cell.Thus, When the neuron is at rest, the primarily responsible for moving potassium ions OUT of the cell - concentration gradient

Bacteria can regulate gene expression due to changes in the environment. How are these changes communicated to the cell?
Bacteria adjust their gene expression to environmental changes through mechanisms such as production of alarmones, quorum sensing, and use of regulatory molecules like repressors, activators, and inducers.
Explanation:Bacteria can regulate gene expression in response to environmental changes through different mechanisms. When exposed to different environmental cues, such as change in nutrient levels or cell density, bacteria can adjust their gene transcription to favor survival. They achieve this using alarmones, intracellular molecules produced in relation to environmental stressors.
Some bacteria employ quorum sensing, a mechanism where they produce chemical signals that detect population density and regulate gene expression accordingly. Further, bacteria can alter the sigma factor of their RNA polymerase in accordance with environmental conditions, enabling a more global change in regulon transcription.
Last but not least, bacteria have certain regulatory molecules such as repressors, activators, and inducers that can affect gene transcription. Activators and repressors are cellularly-produced proteins that control gene transcription by binding to specific DNA sites. Inducers, on the other hand, are small molecules that may be produced by the cell or present in its environment. Their role is to activate or repress transcription based on the cell's needs and substrate availability.

In the Great Lakes, there are over 3,500 types of organisms that cannot produce offspring with each other. All of these different types of organisms create a wide variety of wildlife.
Which type of biodiversity does this example describe?
A
ecosystem diversity
B
genetic biodiversity
C
nutrient biodiversity
D
species biodiversity
Answer:
B
Explanation:
The genetics are the coding to the animals physique, so it only makes sense for the genetics to cause a variety of life.
Final answer:
In the case of the Great Lakes, the term that best describes the over 3,500 kinds of organisms which cannot interbreed is 'species biodiversity.' This refers to the diversity of different species within an ecosystem or across the Earth.
Explanation:
The example of over 3,500 types of organisms in the Great Lakes that cannot produce offspring with each other is a demonstration of species biodiversity. This term refers to the variety and abundance of different species in a certain ecosystem or on the Earth as a whole.
Genetic diversity is a related concept but refers to the variety of genes within a population, while ecosystem diversity is about different ecosystems and their interactions. The specified example does not pertain to genetic or ecosystem diversity, nor does it involve nutrient diversity which is not typically classified as a biodiversity type.
Therefore, the correct answer to the question is D, species biodiversity.
The darker parts occur on the cooler parts of the cat's body because the enzyme that catalyzes the formation of the dark pigment is more active when cool. This example shows that enzymes are affected by .
Answer:
The correct answer is - temperature.
Explanation:
These cats have an enzyme that acts on the body temperature of the body. Siamese cats are characterized by the dark and light regions on their fur. The dark region is present on the cooler side of the body of the cat due to the formation of dark pigment.
The dark pigment formation occurs due to the specific enzymes that are affected by the temperature because the pigment is active on the cool temperature in cats.
Thus, the correct answer is - temperature.
Answer:
By temperature
Explanation:
Enzymes like proteins are affected by temperature change.
Who were two of the most important anthropologists in the development of evolutionism in anthropology?
Answer:
Sir Edward Burnett Tylor & Lewis Henry Morgan.
Explanation:
Anthropology may be defined as the field of science that mainly deals with the study of the human and its behavior. The evolutionary study of human is done in Anthropology.
Burnett Tylor & Lewis Henry Morgan gave the first theory on the anthropology. They explained the impact of the society on the behavior and evolution of organisms. According to them, the development of the society is based on the order of the culture and occurs at different rate. They explain the social evolution in anthropology.
Thus, the answer is Burnett Tylor & Lewis Henry Morgan.
Answer:
Sir Edward Burnett Tylor & Lewis Henry Morgan
Explanation:
Edward Burnett Tylor is known as the founder of cultural anthropology as proposed an evolutionary theory that is progressive and include historical evidences and relationships from primitive ages to modern cultures.
While Lewis Henry Morgan invented the study of kinship terminology and also introduced the concept of universal cultural evolution. The kinship terminologies represented the worldwide classification system both in the new and old world ages.
Hence, these two play the most important role in the development of evolutionism in anthropology
