The type of cell division being shown is meiosis. Meiosis creates four haploid cells. The genetic material is exchanged between the cells during meiosis, meaning that the four daughter cells of each have a different variant of the genetic information.
The answers would be histones; nucleosomes.
Sentence form: In the nucleus, DNA is wrapped around histones to form nucleosomes.
This is an example of Precursor gene regulation (protein translation) type of eukaryotic gene regulation.
<u>Explanation:</u>
The source which breakdown proteins into smaller amino acid is pepsin and generated as top cells within stomach lining or membrane, responsible for pepsinogen emission inside stomach. It is represented as zymogen having an extra 44 amino acids linkage as its primary structure. Hydrochloric acid (HCl) releases this zymogen which is emitted from the parietal cells in the stomach lining.
Once food is consumed, the hormone gastrine and the vagus nerve cause the secretion of both pepsinogen and HCl from the stomach lining. Hydrochloric acid induces an acidic environment that allows pepsinogen to unfold in an autocatalytic manner and thus generates pepsin the active form.
Concentrate Odorants is the answer.
Cause mammals are the only species that are well developed before birth unlike marsupial and monotremes
