Kipish [7]

Answer:

See

Explanation:

Given:

Brown allele (B) is dominant over the white allele (b).

It will be assumed that the alleles are not related to the X and Y chromosomes.

See attached diagram for details of the general case (for both homo-zygous and hetero-zygous parents)

For both parents hetero-zygous,

P1:

Genotype: Bb (100%)

Phenotype: brown (100%)

F1:

Genotypes : BB, Bb, bB and bb in equal proportions, i.e.

BB (25%), Bb (50%), bb (25%)

Phenotypes: 75% brown (from BB and Bb), 25% white (from bb)

Sveta_85 [38]

Answer:

Inhibits

Explanation:

Some mechanisms are essential for maintaining homeostasis in the human body. One of the most used mechanisms by our body is the negative feedback system. It causes a negative change from the initial change. As mentioned in the question, this often happens in the hypolamo-pituitary axis, such as when the adrenal cortex produces cortisol, this same cortisol inhibits the adenohypophysis and hypothalamus. It's also important to mention that deregulation in this process can lead to an undue chronic increase in cortisol and can lead to diseases such as anxiety disorder.

AURORKA [14]

Answer:

Part A....B

Part B....C

Explanation:

It should be understood that Mice are always first used to clinical test especially for drugs or other things that are supposed to be for human use, this is because Mice and human genetic disorders have arisen from conserved and related evolutionary processes. Therefore, when the clinical trial or test produces a positive result in the Mice, it is almost certain that the result will be the same in human.

Now in part B. When the result result is different, it might be because of the differences in anatomy and physiology might hide or change development and symptoms of disease. And that is the reason why, the result of a particular drug differs from person to person.
