Answer:
B. Proteins
Explanation:
Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).
Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.
The answer to this is Axial
Answer:
Explanation:
Purple flowers (P are dominant to white (p), and long pollen (L) is dominant to short pollen (l).
A true breeding variety of peas with purple flowers and short pollen is crossed to a true breeding variety with white flowers and long pollen.
Parent genotype PPll x ppLL
F1 genotype will be PpLl
self crossing of F1 PpLl x PpLl
b. What proportion of the F2 will have purple flowers with long pollen?
Pp x Pp = 3/4 purple flowers, 1/4 white flowers
Ll x Ll = 3/4 long pollen, 1/4 short pollen
Thus answer is 3/4 x 3/4 = 9/16 purple flowers with long pollen
c. What proportion will have white flowers and short pollen?
thus, answer is 1/4 white flowers x 1/4 short pollen = 1/16.
The organism could effect the food chain, amount of recourses, and how organisms in that community interact.
