BS Zoology Semester Exam MCQs

A spermatheca allows females of many insects to store sperm after mating. Stored sperm may fertilize eggs later, improving reproductive flexibility.

Diapause is a developmental arrest synchronized with seasonal stress such as cold or drought. Hormonal control helps insects survive until conditions improve.

Most insects use internal fertilization. This protects gametes from drying and supports reproduction in terrestrial environments.

Social insects such as bees, ants, and termites show cooperation, division of labor, and communication. These traits allow colonies to function as highly organized units.

Egg maturation involves growth of the oocyte, yolk deposition, and formation of protective egg coverings. These processes support early embryonic development.
