Answer:

Explanation:
Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.
There are three phases in interphase G1, S and G2. During this phase cell undergoes several changes that include cell grows, DNA replicates and prepare itself for mitosis.

Answer:
<h3>A) Enzymes are highly specific protein catalysts</h3>
Explanation:
- Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
- Enzymes have an active site by which it binds to substrate at that specific site.
- Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
- Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.
Answer:
d. They always invade the human body from the external environment
Explanation:
Antigens are the molecules that have the ability to stimulate immune response and are mostly protein in nature. However, an antigen may be self or non-self molecule.
This means that antigen may enter the human body from the external environment (the non-self antigen) or any molecule present inside the body may serve as antigen (self-antigen). Self-antigens are responsible for autoimmune disorders.
