Answer:
Hormones act only on cells not structures.
Explanation:
Hormones act only on cells and they do not act on other structures because there are specific cells have receptors for that particular hormone. Some hormones bind itself to the receptors on the surface of target cells whereas other hormones enter the cells and bind itself to the receptors present in the cytoplasm or nucleus of the cell.
Answer:
2) disruptive selection
Explanation:
Disruptive selection is a type of natural selection that acts against less fit heterozygotes. The disruptive selection can be represented by a decrease in the variance of a trait. In this case, the disruptive selection eliminates the medium-sized beaks, thereby favoring the extreme phenotypes in an interbreeding population.
Given the scenario, their progeny will heterozygous or BbEe.
A purebred white mouse and a purebred black mouse are being crossed.
<h3>
What is homozygous?</h3>
A gene region where there are two identical alleles present. Two alleles with the same variation or two alleles that are normal can both be present in a homozygous genotype.
BBEE is black fur.
Bbee has white fur.
Here, the capitalization of allele B signals that it is a dominant allele and that allele B is recessive.
For BBEE, gametes
BE a, b, e, b
Genes for the bbee
a, a, a, a Cross will then have an image linked to it.
As a result, in the example, their progeny would either be BbEe or heterozygous.
