what is the answer choices
Immunity may be defined as the body's ability to produce cells that inactivate foreign cells or substances.
<h3>What is the significance of best immunity?</h3>
The significance of the best immunity shields us by first constructing a barrier that prevents those invaders, or antigens, from entering the body.
The body's ability to produce the "fight or flight" response is stimulated by the sympathetic nervous system. The body's ability to regulate homeostasis through feedback loops by maintaining the process of homeostasis.
Therefore, immunity may be defined as the body's ability to produce cells that inactivate foreign cells or substances.

Answer:
The R chain gives an amino acid its unique identity
The hydrogen, carboxyl and amine groups are similar parts of all amino acids.
Explanation:
Amino acids are building blocks of protein molecules. They are 20 amino acids in nature, however, these amino acids are similar in structure but differ in the possession of different side chains, also called R chain.
- All amino acids have in their structure a hydrogen group (-H), an amino group (-NH2) and carboxyl group (-COOH). All these are attached to one carbon atom called the CENTRAL CARBON in the structure.
- A fourth group called "R chain" exists in the amino acid structure that differentiates all amino acids. This means that no two amino acids have the same R chain side group. For example, Alanine has a methyl group (-CH3) as its R side group while Glycine has hydrogen (-H) as its.
