Mitosis
Explanation:
Mitosis is a type of cell division in which a cell divides into two daughter cells each having the same number of chromosomes as the parent cell.

The cell that have 78 chromosomes have undergone mitosis while the other cells that contain 39 chromosomes undergo meiosis.
Answer:
B
Explanation:
Directional selection tends to evolve towards one specific trait. In this example, white rabbits no longer have a competitive advantage because of disappearing snow. This means they are more easily spotted by predators, resulting in reduced fitness and less chance they will live to reproductive age and pass their recessive white alleles on.
Natural selection will favor the gray colour allele, increasing the frequency oft this previously rare allele.
