Question

during fertilization in multicellular organisms, a sperm cell fuses with an egg cell to form a zygote. then, the zygote begins to divide. first, one cell becomes two, then two cells become four, four cells become eight and so on and so forth until a large ball of identical cells is formed.
the zygote divides and produces more cells through the process of
a. implantation
b. specialization
c. meiosis
d. mitosis

Explanation:

• Implantation is the attachment of the embryo to the uterine wall.
• Specialization refers to cells developing specific functions.
• Meiosis is a type of cell division that reduces the chromosome number by half, used in gamete formation.
• Mitosis is the process by which a cell divides to produce two daughter cells that are genetically identical to the parent cell. This is the process by which a zygote divides to produce more cells.

Answer:

D. mitosis
