this is pretty much what it should be because we dont have any other answer choices
Answer:
1. X chromosome inactivation
Explanation:
X chromosome inactivation is a process that shuts down one X chromosome in all the cells of a female during early embryonic stages. It is done to balance the dosage of X-linked genes in males and females. The process of X chromosome inactivation is random which means that either paternal or maternal X chromosome may be inactivated in the cells. The inactivated X chromosome in a cell is transmitted to all of its daughter cells.
Therefore, some cells of a female express the paternal X chromosome while others express the maternal X chromosome. The random expression of the paternal or maternal X chromosome in females results in patches of cells with or without sweat glands.
Convergent evolution would be the best way to explain why two species that look similar are not necessarily that closely related. In convergent evolution, distinct species develop similar anatomical characteristics after its divergence from one common ancestor that does not possess the initial characteristic.
<span>Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid. </span>
I know DNA and stuff is super hard to learn I had to look at my old notes.
