Answer:

The correct answer is C) amylase

Explanation:

Amylase is the enzyme which is present in our saliva and is also produced by the pancreas called pancreatic amylase. Amylase enzyme is used in the body to digest starch present in our food to glycogen and then glycogen into simple sugars.

Therefore as amylase is used to digest complex starch into simple carbohydrate therefore amylase is the enzyme that can be effective in removing the starch from the blue jeans.  Lipase breaks down lipid, cellulase breakdown cellulose, protease breaks down proteins, and lactase breakdown lactose.

The correct answer is option A) "True".

Explanation:

Paracrine hormones are a type of eicosanoids (signaling molecule), which are characterized for binding and performing its function on nearby cells rather than the cells where they are produced. Two examples of paracrine hormones are estrogens and testosterone. Estrogens are produced by the ovaries, but they perform their function on ovarian follicles. Testosterone is produced by the Leydig cells of the testes, but they perform their function on adjacent seminiferous tubules.

Consider the two types of sudoriferous glands. Then click and drag each label into the appropriate category to determine whether it applies to apocrine glands, merocrine (eccrine) glands, or both.

-Not active until puberty

-Use myoepithelial cells to secrete

-Secrete sweat

-Found in pubic and axillary regions

-Secrete pheromones

-Abundant on hands, feet, and forehead

-Found over entire body

-Scent is meant to attract a potential male

-Thermoregulation

-Utilize ducts to release sweat

Apocrine Glands:

-Not active until puberty

-Secrete pheromones

-Found in pubic and axillary regions

-Scent is meant to attract a potential male

Merocrine Glands:

-Found over entire body

-Thermoregulation

-Abundant on hands, feet, and forehead

Both Apocrine and Merocrine Glands:

-Secrete sweat

-Use Myoepithelial cells to secrete

-Utilize ducts to release sweat

The apocrine and merocrine glands are the subcategories of the sudoriferous glands which secrete the different types of secretions like sweat and oils. Both of them have myoepithelial cells.

The apocrine glands are mainly dependent on the sex hormones and are mainly present in the public region, beard etc. The sweat secreted from these glands are rich in fatty acids and other pheromones. These glands are regional in nature. But the merocrine glands are not hormonal in nature. They are distributed all over the body and secrete sweat whose primary function is to lower body temperature.

Apocrine Glands: These glands are associated with hair follicles and release a thicker, odorless secretion. They are primarily found in areas like the armpits and groin.

Merocrine (Eccrine) Glands: These glands release a watery, odorless sweat directly onto the skin's surface and are distributed all over the body, assisting in temperature regulation.

Both: Both types of glands are involved in regulating body temperature through sweat production. However, their secretion composition and distribution differ.

Sudoriferous glands, also known as sweat glands, encompass two primary types: apocrine and merocrine (eccrine) glands. Apocrine glands, predominantly found in regions like the armpits and groin, produce a thicker secretion associated with body odor.

In contrast, merocrine or eccrine glands release a watery and odorless sweat directly onto the skin's surface, distributed across the entire body, playing a pivotal role in regulating body temperature. Both types of glands participate in thermal regulation by promoting sweat production, although their secretions differ in composition and distribution. Understanding these distinctions is crucial in comprehending how our bodies manage temperature and maintain overall homeostasis.

Explanation:

A) Pili; bacterial conjugation for reproduction

b) Fimbriae;  Allow bacteria Adhesion to host cell

c) Flagella; Allow for motility

d) Glycocalyx;promotes adhesion and interferes with phagocytosis

Final answer:

The correct statements about prokaryotic external appendages are that a. Pili allows for adhesion, movement, and aid in gene transfer through conjugation; c. Flagella allows for motility; and d. The glycocalyx promotes adhesion and interferes with phagocytosis.

Explanation:

When examining the true statements about prokaryotic external appendages, we can identify the following:

While fimbriae aid in attachment to surfaces and other cells, they are not typically involved in gene transfer through conjugation; this process is primarily facilitated by pili. Therefore, the statement concerning fimbriae aiding in gene transfer through conjugation is not true.

Answer:

B-D-C-A.

Explanation:

The chromosome map helps to understand the location of genes in the genome map. The distance between the genes can be used to locate the genes of chromosome.

The distance between the Band D is 5%. The B and D gene can be located with each other. Then gene C is located after D and the distance between them is 15%. This will give the distance between B and C is 20%.  The gene A is located at the last position A and the distance between them 30%.

Thus, the correct answer is B-D-C-A.

Chromosome map: A-B-C-D. Distances: A-B > B-C > C-D. Recombination: A-D=25%, A-B=30%, C-D=15%, B-D=5%, B-C=20%.

A chromosome map, also known as a genetic map or linkage map, illustrates the relative positions of genes along a chromosome based on the frequency of recombination events between them. Recombination occurs during meiosis when genetic material is exchanged between homologous chromosomes.

Given the recombination percentages between genes A, B, C, and D, we can construct a chromosome map:

1. A to D = 25%: This indicates that 25% of the offspring exhibit recombination between genes A and D.

2. A to B = 30%: Similarly, 30% of the offspring exhibit recombination between genes A and B.

3. C to D = 15%: 15% of the offspring exhibit recombination between genes C and D.

4. B to D = 5%: Only 5% of the offspring exhibit recombination between genes B and D.

5. B to C = 20%: And 20% of the offspring exhibit recombination between genes B and C.

From these percentages, we can infer the relative distances between the genes. The order of the genes on the chromosome would be A - B - C - D. Additionally, we can deduce the map distances between adjacent genes.

For example, the distance between A and B would be greater than that between B and C, as indicated by the higher recombination percentage between A and B.

Final answer:

To calculate the acceleration of the blood, the kinematic equation[tex]a = (v^2 - u^2) / (2 * s)[/tex]is used, considering the final speed is 30.0 cm/s, initial speed is 0 cm/s, and distance is 1.80 cm, which gives an acceleration of [tex]250 cm/s^2.[/tex]

Explanation:

The question asks about determining the magnitude of acceleration that the blood experiences when accelerated by the left ventricle of the heart from rest to a certain speed across a particular distance. To calculate this, we can use one of the kinematic equations that relate acceleration, final velocity, initial velocity, and displacement:

[tex]a = (v^2 - u^2) / (2 * s)[/tex]

where v is the final velocity (30.0 cm/s), u is the initial velocity (0 cm/s as the blood starts from rest), and s is the distance covered (1.80 cm).

Plugging the values into the equation:

[tex]a = (30.0 cm/s)^2 / (2 * 1.80 cm)[/tex]

[tex]a = 900 cm^2/s^2 / 3.60 cm[/tex]

[tex]a = 250 cm/s^2[/tex]

Therefore, the magnitude of the acceleration of the blood is [tex]250 cm/s^2.[/tex]

It is not possible to study the genes that cause disease using the molecular clock.

Explanation:

The molecular clock technique is an important tool in molecular systematic, the use of molecular genetics information to determine the correct scientific classification of organisms or to study variation in selective forces. A nice aspect of molecular clocks is that different genes evolve at different rates, which gives us flexibility to date events throughout the history of life" Hedges points out. Broadly speaking, the evolution of important genes occurs more slowly than that of genes with less vital functions.

In order to develop a molecular clock, one would need: a sequence of molecules, the rate at which changes occur in a type of molecule and how much total change has occurred in a type of molecule from different species.

Emotion  is a neural drive that moves a living organism to action, provoking automatic reactive behavior that has been adapted through evolution as an survival mechanism to meet a survival need. In simple words we can say that Emotion is a mental state related with the central nervous system, several chemical messengers released in neural signal transmissions are responsible for different emotions like happiness, sadness, difference in thoughts etc

Answer:

Social Conflict Theory.

Explanation:

The social conflict theory was given by the Karl Marx which believes that conflict among the society is common and the historical fights might occur due to the conflict reason.

The different groups present in the society are involved more in conflict with each other rather than on the basis of the consensus. The minor offenses create conflict  in the court against the king and people start share their veiws to conflict against the king.

Thus, the answer is social conflict theory.

Final answer:

The theory that aligns with the lawyer's view on the justice system possibly sustaining King's delinquent behavior is the Labeling Theory. This theory suggests that societal labels, such as being called a delinquent, can influence an individual's behavior and self-identity, potentially leading to a cycle of crime. The interaction with the criminal justice system might reinforce rather than deter criminal behaviors.

Explanation:

The theory that aligns with the lawyer's view that the justice system may actually be sustaining, rather than inhibiting King's behavior is the Labeling Theory. Labeling Theory suggests that the labels people are given by society, particularly those in positions of authority such as the criminal justice system, can influence their self-identity and behaviors. This theory posits that by labeling someone as a delinquent or criminal, the system can inadvertently confirm the individual's delinquent identity, making it more difficult for them to break out of a cycle of crime. Labeling someone as a 'criminal' can lead to a self-fulfilling prophecy where the labeled individual conforms to the expectations of that label.

In King's case, the continuous interaction with the juvenile court system and the subsequent labels attached to him might be reinforcing the behaviors that bring him back into the system, rather than deterring future criminal activities. This embodies the criticism within the Labeling Theory towards the criminal justice system's approach to handling juvenile delinquency, as it might perpetuate the very behaviors it aims to stop.

Answer:

The answer is "Primary Somatosensory Cortex".

Explanation:

The sensations we experience such as touching something warm or cold, extending our muscles and limbs and changing their locations and orientations are collectively called somatic sensations and they are processed in the brain's "Primary Somatosensory Cortex". So the answer of the primary target area in the cortex of our brain for information of muscle stretch etc is the primary somatosensory cortex.

Answer:

Both cells would lose water, the red blood cell would shrivel and the plant plasma membrane would pull away from the cell wall.

In seawater, which is hypertonic, red blood cells might shrink and die due to losing water, disrupting cellular processes. Plant cells, with protective cell walls, can survive better but under extreme concentrations may also lose water and undergo plasmolysis.

If a red blood cell and a plant cell were placed in seawater, different things would occur due to the high concentration of solutes (salt) in the water. Seawater is hypertonic compared to the cellular fluids, which means it has a higher concentration of solutes.

Red blood cells will lose water and shrink or crenate. This occurs due to osmosis, the movement of water from a lower concentration of solutes (inside the cell) to a higher concentration (outside in the seawater), until equilibrium is reached. Losing water disrupts the balance of solutes, making the cytosol denser, interfering with diffusion, compromising the cell's ability to function, and it may result in cell death.

On the other hand, for plant cells, their cell walls allow them to withstand the pressure better than red blood cells. However, if the concentration becomes too extreme, plant cells may also lose water and enter a state known as plasmolysis.

Biopsychology is the perspective that combines the science of the mind and the science of the brain.

The perspective that can be described as a marriage between the science of the mind and the science of the brain is biopsychology. Biopsychology, also known as behavioral neuroscience, is a field that combines biology and psychology to study how the brain and nervous system influence behavior and mental processes. It examines the physiological processes and structures that underlie psychological processes and behavior.

For example, biopsychologists may analyze how changes in neurotransmitter levels can affect mood disorders like depression, or how brain injuries can impact memory and cognition. This interdisciplinary approach helps bridge the gap between the study of the mind and the study of the brain, providing a comprehensive understanding of the biological basis of behavior.

The parts of the brain implicated in ADHD, such as the prefrontal cortex and the basal ganglia, feature large amounts of __dopamine__ activity. Many of the medications used to treat ADHD work by boosting the activity of this chemical.​

Explanation:

Attention deficit hyperactivity disorder (ADHD) is a medical condition in which patient brain has differences in brain development and activity. This can affect ability of sitting still, attention and self control. Moreover, children can be affected at home, at school and in friendships. (See attached Detailed info graph)

The parts of the brain implicated in ADHD, such as the prefrontal cortex and the basal ganglia, feature large amounts of dopamine activity. Many of the medications used to treat ADHD work by boosting the activity of this chemical.

The parts of the brain associated with ADHD exhibit significant dopamine activity, and treatments often aim to increase dopamine levels through medications. Medications like methylphenidate (Ritalin) and amphetamine with dextroamphetamine (Adderall) elevate dopamine levels, which can help in managing ADHD symptoms. These medications are effective because individuals with ADHD often show decreased dopamine activity in key brain regions associated with motivation and reward. This decrease in dopamine activity is thought to contribute to difficulties in impulse control and motivation which are hallmark symptoms of ADHD.

Transfer = 10/100 of total energy.

Explanation:

Energy and matter is transferred from one organism to another by the process of food chain and food web. In food chain the organism of higher trophic level feeds on the organisms of lower trophic level. On feeding only 10% of the energy gets transferred to the organism of higher trophic level while the rest are being used in the metabolic processes and are produced as heat. This is called as ten percent energy transfer rule.

The mathematical representation of the transfer of energy is given as

Transfer = 10/100 of total energy.

Answer:c

Explanation:

Answer:

B) The gene involved is on the X chromosome.

Explanation:

Thomas Hunt Morgan performed the experiments on the Drosophila and found that genes are located on the chromosomes which are passed o during the reproduction and called it the chromosomal theory of inheritance.

Morgan crossed the white-eyed male mutant to the red-eyed female, a wild trait for eye and observed that during F₁ generation the all-male and female were red-eyed but in F₂ generation only the red-eyed females were produced but all the males were white-eyed.

He found that the gene for the eye colour trait can be linked to the sex of the fly and concluded that it followed the X inheritance pattern as the gene is located on the X chromosome.

Thus, Option-B is the correct answer.

Answer:

Option B, The gene involved is on the X chromosome.

Explanation:

Morgan conducted his studies on Drosophila flies in 1910. He first time noticed a fly with a distinctive white color eye instead of red. Out of curiosity he crossed the white eye fly with a normal red eye fly and noticed that white eyed fly appeared in the second generation and all white eyed flies were male. For the first time, it was observed that some genetic traits are sex linked. In this case the white eye trait was X linked and hence this trait could not appear in female as they have another normal red eye dominant allele which over expressed the white eye allele. However, in male there is no second X chromosome and hence white eyed male possesses recessive white eyed X –chromosome.

Hence, option B is correct
