question 5 of 10
how does pregnancy begin?
a. contraction
b. differentiation

Explanation:

Pregnancy begins when a sperm fertilizes an egg. Fertilization is the process where the sperm penetrates the egg, forming a zygote. Contraction is related to labor (muscle tightening). Differentiation refers to cells becoming specialized. Deviation means moving away from a standard. So, fertilization is the correct start of pregnancy.

D. Fertilization
