Question continuation;
..........type B. Type A is found to be more common in the mainland population from which the island was settled.
How could a geneticist best explain the dominance of blood type B in the island population?
Multiple choices;
A. Random mutations have occurred in the island population.
B. Genetic drift has reduced the frequency of type A individuals.
C. Natural selection has only occurred in the mainland population.
D. Environmental conditions on the island are less favorable for type B individuals.
Answer;
B. Genetic drift has reduced the frequency of type A individuals.
Explanation;
-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.
-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Explanation:
<h3><u>Expansion of energy in active transport:</u></h3>
- Active transport is a transport process that involves movement of molecules between regions through a membrane against the concentration gradient.
- It is homeostatic process which means it’s a biological process in which functions of the body are regulated to achieve internal balance.
- Active transport uses metabolic energy ATP to transport molecules across a membrane.
- Generally, metal ions are transported across cell membrane by active transport.
- Metal ions are transported with the help of ion pumps and are distributed through the body.
