Answer:

D). genetic drift

Explanation:

Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.

For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.

Answer:

In the case of poor nutrition, it happens that the increase in cholesterol that we call "bad" LDL occurs and the "good" HDL cholesterol that is protective and sweeps the bad that covers the blood vessels is not increased. Taking into account diabetes, the excess glucose produced in the body, glycosylates the LDL particle, which also obstructs the passage of blood flow through the vessels.
