They speed up the breakdown of food in the stomach.
Answer:
C) Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways.
Explanation:
Apoptosis is a natural process taking in the cell which causes the physiological and biochemical changes in the cell which could cause the death of the cell.
The apoptosis is controlled at the genetic level therefore apoptosis is also known as the programmed cell death.
The studies have shown that the process is involved in the development of the finger and the toes in humans and the sequences controlling the process has been conserved during the evolution in a different organism.
This shows that humans and nematode have the same conserved sequence of apoptosis but the natural selection does not control the apoptosis.
Thus, the selected option is the correct answer.

Answer:
Density, dispersion, growth
Explanation
Population refers to the total number of all members of a species occupying a particular area or habitat at a given time. Populations are not static but change in size, structure and organization. Some of the characteristics of population are:
- Density which refers to the number of members of a species per unit area or volume.
- Dispersion refers to the spread and distribution of individuals of a species within a habitat.
- Growth is the rate of increase or decrease in the number of individuals in a population which is balanced by birth rate and death rate.
The issues that affect population include competition, predation, emigration, diseases and parasites.
