_____ lobe development during adolescence often lags behind limbic system development, which may help explain impulsiveness, risky behaviors, and emotional storms that often accompany adolescence.
Frontal lobe development during adolescence often lags behind limbic system development, which may help explain impulsiveness, risky behaviors, and emotional storms that often accompany adolescence.
Explanation:
In adolescents, the development of frontal lobe is observed to lag behind the limbic system development. This process is controlled by factors like environmental, heredity, pre and postnatal insult, sleep pattern, nutrition etc.
The frontal lobes are engaged with development control, critical thinking, suddenness, memory, language, commencement, judgment, motivation control, and social and sexual conduct. Adolescents process information with the amygdala which is the emotional part.
In adolescent’s brain, the associations between the emotional part of the brain and the decision-making center are still developing and not always at the similar rate. That is the reason when adolescents have overwhelming emotional input, they can’t explain later what they were thinking.

-from the Golgi apparatus and the rough ER to the cytoplasm and the nucleus
-from the rough ER to the Golgi apparatus
-from the Golgi apparatus and the rough ER to the cytoplasm and the mitochondria
-from the cytoplasm to the Golgi apparatus
Answer:
-from the Golgi apparatus and the rough ER to the cytoplasm and the mitochondria
Explanation:
Proteins which have to be secreted , pass through the secretory pathway in the following order:
From the Rough Endoplasmic Reticulum (where they are synthesized ) moves to Golgi transport vesicles to the Golgi cisternae and secretory or transport vesicles are formed which then move to the cell surface by passing through the cytoplasm and by exocytosis move outwards. Small transport vesicles bud off from the endoplasmic reticulum and join to form the Golgi reticulum.
Hence the correct answer is that the labeled proteins to go from the Golgi apparatus and the rough ER to the cytoplasm and the mitochondria during the chase.

Prior to the elucidation of the genetic code, prominent scientists, including Francis Crick, had predicted that each mRNA codon, coding for one of the 20 amino acids, needed to be at least three nucleotides long. Why is it not possible for codons to be any shorter?
Answer:
The genetic code may be defined as the triplet code of the nucleotides that codes for the particular amino acids. This genetic code is heritable in nature and mutation is these code can cause disease.
The codons cannot be shorter because the least three nucleotides only allows the combination of the 64 possible that contain 4 different nucleotides. These nucleotides are possible at the three different position within the codon.
When polluters buy, sell, and trade permits with other polluters, this is called a __________. a. polluter-pays system b. cap-and-trade emissions c. trading system subsidy d. revolving-door policy
Answer:
Option B

Use the scale bar to determine the sizes of a mature parent yeast cell and a cell budding from it. You will then calculate the volume and surface area of each cell. You will use your calculations to determine how much cytoplasm and plasma membrane the new cell needs to synthesize to grow to full size.
Answer: A mature parent cell is approximately 4 µm, while a budding cell is 3 µm. Since the shape of a yeast is a sphere, we can use the formula below:
V= (4/3)π.r³, considering that π=3,14 and r is for ratio of the sphere, which is half of it's diameter.
For a parent cell, the volume is: 33 µm³
For a budding cell, the volume is: 14 µm³
Since the volume determines how much cytoplasm a cell has, then a budding cell needs to grow the mature parent cell - its own current volume, so the result would be 19 µm³ of cytoplasm.
To calculate the surface area, we use another formula that is presented below:
A= 4.π.r²
For a parent mature cell, the surface is 50 µm²
For a budding cell, the surface is 28 µm²
Since the surface determines how much plasma membrane a cell has, to know how much the budding cell needs to grow up to a mature state is simply using the surface area of the parent cell - the current surface area of it, resulting in 22 µm².
To find the size differences between a mature yeast cell and a budding cell, we first calculate their sizes using the scale bar. We apply those sizes to the formulas for surface area and volume of a sphere to find the amount of plasma membrane and cytoplasm the budding cell needs to reach full size. Growth limitations are also discussed by considering the surface area-to-volume ratio.
Explanation:The subject of this question concerns the cellular processes of yeast, which are eukaryotic fungi. Specifically, it deals with the size of yeast cells and their budding - a model of asexual reproduction. Yeast cell size can be found based on the scale bar provided. Assuming these are spherical cells, we can use the formula for sphere volume and surface area (4πr² and 4/3πr³ respectively) to calculate these parameters. Here 'r' is the radius of the cell which will be about half of the determined size.
Initially finding the size of the mature parent yeast cell and the budding yeast cell using the scale bar.Then applying the formulas to calculate their volume and surface area.Subtract the calculated measurements of the budding cell from the mature cell to find the increase. This will represent the amount of plasma membrane (surface area) and cytoplasm (volume) the budding cell requires to grow to full size.It's important to note that as a cell increases in size, its surface area-to-volume ratio decreases. This is crucial for understanding cell efficiency and the need for cell division when the cell gets too large.

A researcher is trying to create an artificial, eukaryotic cell-like membrane within the laboratory. She wants this membrane to be able to resist osmotic pressure. If she wants the membrane to have this trait, what should she make sure is a component of her artificial membrane?
Answer:
The correct answer is - cholesterol.
Explanation:
Osmotic pressure is the pressure that is applied to a solvent without any solute particle to prevent it from entering inward into a specific solution by the process of the osmosis.
In a cell to prevent osmosis or resistance to the osmotic pressure a cell membrane need to be have cholesterol as it is hydrophobic in nature and most of the solution have water as solvent.
Thus, the correct answer is - cholesterol.
inheritance of biological characteristics is determined by individuals units known as genes. In organisms that reproduce sexually, genes are passed from parents to their offspring. In cases in which two or more forms of the gene for a single trait exist, some forms of the gene may be dominant and others may be recessive. In most sexually reproducing organisms, each adult has two copies of each gene one from each parent. These genes are segregated from each other when gametes are formed. The alleles for different genes usually segregated independently of one another
Genes are units that determine biological characteristics of individuals, with variations known as dominant or recessive. They separate or segregate when sexually reproducing organisms reproduce, and different genes usually assort independently.
Explanation:The inheritance of biological characteristics in individuals is indeed determined by units known as genes. In sexually reproducing organisms, each parent contributes one set of genes to their offspring. These genes determine the traits or characteristics of the offspring. If a gene has more than one form, or allele, these variations can be dominant or recessive. Dominant alleles will express their trait even if only one is present. Recessive alleles will only express their trait when two copies are present. The process by which these genes are separated and passed on when organisms reproduce is called segregation. Additionally, different genes tend to assort independently, a principle known as independent assortment.

Uric acid is transported across epithelial cells in the kidneys by an organic acid transporter (OAT) membrane transport protein. The presence of another organic acid, probenecid, causes a decrease in the uric acid transport rate. What characteristic of transporters is demonstrated by the decrease in uric acid transport in the presence of probenecid?
Answer:
Competition
Explanation:
Transportation of some molecules can not be through simple diffusion due to their size or other factors.
Therefore carrier proteins known as transporters are needed to facilitate their transportation.
Transporters exhibit or demonstrate characteristics such as competition,
During competition, presence of a certain molecule decreases the transportation of another molecule.
When Uric acid transportation is decreased due to the presence of probenecid is a good example of competition.
A model of segregation of alteles during meiosis is shown here. A student hypothesizes that failure for chromosomes to segregate
during melosis might impact the phenotype of the resulting offspring, if those gametes are fertilized. What question is most relevant
for the student to ask about the outcome of a lack of segregation of chromosomes?
Answer:
b
Explanation:
The mismatch repair system recognizes mismatched base pairs, removes a portion of the DNA strand containing the error, and then resynthesizes the missing DNA using the correct sequence as a template. But what if the mismatch repair system instead removed a piece of the DNA strand that contained the correct sequence? What would replication of this improperly repaired sequence produce?
A. two DNA molecules that are missing one nucleotide pair
B. two DNA molecules bearing the same mutation
C. two DNA molecules with a gap where the correct sequence was excised
D. one DNA molecule with a mutation and one DNA molecule with a mismatch
E. two DNA molecules with different mutations
Answer:
B) two DNA molecules bearing the same mutation
Explanation:
The mismatch repair system is the biological system of proofreading the DNA strands which takes place after the DNA replication. The system works by recognizing the mispaired bases which could have added due to the insertion, deletion or any replicative error. The mismatched pair removes the wrong bases and then DNA ligases join the DNA.
If the repair system mistakenly removes the DNA with correct sequence then the DNA replication process would form the two DNA strands with the same type of mutation as the DNA replication forms the complementary strands from the two strands of the parent DNA.
Thus, Option-B is the correct answer.
Which of the following statements about natural selection is true? a. Natural selection favors individuals that reproduce more than others. b.Natural selection can be used by farmers to generate organisms with desirable traits. c. Natural selection is a process whereby genes are selected randomly for preservation in the next generation. d. Natural selection occurs in opposition to evolution.
Answer:
The correct answer is a. Natural selection favors individuals that reproduce more than others
Explanation:
Nature select those organisms who are better adapted to their environment and reproduce more and eliminate those individuals who have lower reproductive fitness. This process of selection is called natural selection.
So the selected individual will have more chances to reproduce and produce more offsprings and more the offsprings more will be the chances of survival of offsprings and adaptation. Therefore it is true that natural selection favors the individual who have more reproductive fitness.

Two species of frogs belonging to the same genus occasionally mate, but the offspring fail to develop and hatch. What is the mechanism for keeping the two frog species separate?
a) hybrid inviability,
b) hybrid breakdown,
c) hybrid sterility,
d) gametic isolation,
e) adaptation
Answer:
a) hybrid inviability
Explanation:
Two species of frogs belong to the same genus and interbreed sometimes. It means that the prezygotic reproductive barriers are not working here since the frogs of two species are able to interbreed and produce a zygote. However, the resultant offspring are less viable and do not hatch. It represents hybrid inviability wherein the hybrids of two species do not develop properly during embryonic development and die soon. It is a type of postzygotic reproductive barrier.

A geneticist isolates a gene for a specific trait under study She also isolates the corresponding mRNA Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence. Did the geneticist isolate the wrong DNA? A) yes, mRNA is made from a DNA template and should be the same length as the gene sequence B) yes, the mRNA should contain more bases than the DNA sequence because bases flanking the gene are also C) no, the final mRNA contains only exons, the introns were D) no, the mRNA was partially degraded after it was removed
Answer:
C) no, the final mRNA contains only exons, the introns were removed
Explanation:
Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.
RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.
So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.
Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.

What source of energy would plants release in catabolic reactions? Would an animal release the same kind of energy?
Answer:
Adenosine triphosphate (ATP)
Animals also release this source of energy.
Explanation:
All living organisms require energy to perform their life functions. This energy is obtained by breaking down organic molecules (usually glucose) in a catabolic reaction called CELLULAR RESPIRATION. These organic molecules store energy in their chemical bonds, this energy in a usable form by the cell (ATP) is released when organisms undergo cellular respiration (catabolism).
Plants likewise animals undergo this catabolic process and the same form of energy (ATP) is released for use via this process.

Homeostasis is the ability of the body to A) prevent the external environment from changing. B) prevent the internal environment from changing. C) quickly restore changed conditions to normal. D) ignore external stimuli to remain in a state of rest. E) prevent excessive blood loss.
Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. The body achieves this through mechanisms that restore changed conditions to normal by constantly adjusting certain functions. Examples include regulating body temperature and blood glucose levels.
Explanation:The correct answer to your question about homeostasis is C) quickly restore changed conditions to normal. Homeostasis is the process through which the body maintains a state of equilibrium or stable internal conditions despite changes in the external environment. It functions to ensure consistency within specific parameters for body functions. This dynamic equilibrium is constantly adjusting to changes both internally and externally.
For example, when body temperature rises due to external heat, the body cools itself down through perspiration. On the other hand, if the blood glucose level rises after a meal, the body works to lower it, either by sending the excess glucose to cells that need it or storing it for later use. These are examples of homeostatic mechanisms, which are crucial for the survival and health of an organism.
Through the maintenance of these conditions in a state of dynamic equilibrium, conditions such as body temperature and blood calcium level can be effectively regulated to ensure the smooth functioning of an organism's internal environment.
