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.

The answer is; When the planet is at A it is moving faster than at B.
This is because when the planet is closer to the sun at point A, it is experiencing a stronger gravitation, by the sun, pull than at point B. Therefore, its acceleration due to gravity at point A is higher than at point B.
Answer:Ahingas are secondary consumers in a food web.
Explanation:They are carnivores and there diet includes tadpoles, frog eggs, young alligators, water snakes, etc.
Eukaryotic cells have the ability to absorb other cells by phagocytosis.
<span>Characterized by the presence of the nucleus, formed by a rope DNA (the free ends) surrounded by two layers reticulum (nuclear envelope). Eukaryotic DNA forms a complex with a large number of proteins</span>
