Question

cleavage
a is cell division with no increase in size of the ball of cells
b is mitotic
c occurs immediately after fertilization
d all apply.

Explanation:

Cleavage is a series of mitotic divisions that occur immediately after fertilization. During cleavage, the zygote divides into smaller cells called blastomeres. The overall size of the embryo (ball of cells) does not increase significantly during cleavage because the cells are dividing without significant growth. Mitosis is the type of cell division involved in cleavage. And it starts right after fertilization. So all the statements (A, B, C) are correct.

Answer:

D. All apply.
