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.
Answer:
e. The statement is true for meiosis I only.
Explanation:
When we talk about homologous chromosomes, we talk about two chromosomes forming a pair of genes. One comes from the mother, and one comes from the father in sexual reproduction.
The random segregation of chromosomes is what we call the result of crossing over during meiosis I, and is what generates genetically unique individuals in each reproduction.
