<h2>The Cell cycle</h2>
Explanation:
Mitosis takes place during m phase of the cell cycle.
- True
The cell cycle is the series of event in which a cell duplicates in material and eventually divides into daughter cells.
The cell cycle is broadly divided into two phases.
Interphase- During this phase the cell duplicates its contents and genetic material.
M-phase- During M-phase true cell division takes place.
Cell division is of two types- Mitosis and meiosis.
So we can say that mitosis takes place in the m-phase of the cell cycle.
Answer:
4. The kinetics for the enzymatic processes of microorganisms responsible for decomposition are slowed.
Explanation:
Generally most enzymes work best at optimum temperature of 35-40 degree centigrade, This is because enzymes are proteins, and proteins are sensitive to temperature.
Therefore at low temperature of refrigeration below -18 degree, enzymatic processes of microorganisms need for biochemical activities, oxidative activities and growth are slowdown(thus microorganism population is reduced) . Microorganisms are inactive. Therefore the rate of food decomposition is slowed down,which prolonged nutritional value of the food.
Natural selection can change in a population in multiple ways.
1) natural selection can lower a population by death (an example would be a plague)
2) A population can adapt to the natural selection (an example would be anti bodies for the plague)

Often, the offspring inherit most of the parental variations. For instance, my mother's side has great resistance to cancer. (Many people have had it, but no cases lasted longer than a few months.) My father's side succumbs to heart disease.
I can somewhat expect I might have one in the future.
