A large protein molecule responsible for facilitating biochemical reactions within the body. ... Chemical substances that are absorbed by the body through the process of digestion. nutrition. The proper supply of nutrients essential for growth, reproduction, repair, immunity, and energy.
D
Answer:
Digestive system breakdown small proteins into amino acids by chemical digestion using enzymes (option B).
Explanation:
One of the main functions of the digestive system is to degrade food to facilitate its absorption at the intestinal level. This degradation has a mechanical phase, which includes chewing and contracting the stomach, and an enzymatic phase.
The enzymes that allow the breakdown of proteins into amino acids are called proteases, or peptidases. They are enzymes capable of breaking peptide bonds, obtaining at the end amino acids that can be more easily assimilated by the organism.
<em>The other options are not correct because </em><u><em>mechanical digestion</em></u><em> reduces the size of the digested food and mixes it with the gastric juices, but does not break the peptide bonds.</em>
Behavior = physical action that people take consciously.
Socialization = the process through which a person learns about the norms of one’s culture, including how you’re supposed to behave in various situations, what values you’re supposed to consider to be important, and the roles that men and women are supposed to play.

Answer:
c. Vitamin B12 deficiency
Explanation:
Vitamin B12 deficiency is the cause of many diseases, from anemia to thrombosis. This deficiency is not common in the US, however, it is easily caused by inadequate gastric acid secretion secondary to gastric resection, use of drugs that suppress gastric acid, or gastric infection by Helicobacter pylori.
Vitamin B12 is essential for red blood cell formation, integrity and maturation. In their absence, they increase in volume. In the bone marrow - where they are produced - the number of cells increases so much that the appearance simulates that of leukemias.
It is a necessary vitamin for the development and maintenance of nervous system functions. Without it, the myelin that covers the nerves (as the protective cap does with the electrical wires) suffers wear that is called demyelination, a process that occurs in both peripheral nerve neurons and those in the white matter of the brain.
The main source of B12 is in animal foods. But to absorb it, the digestive tract depends on intrinsic factors present in a special group of stomach cells (parietal cells) and receptors located in the ileum.
