Question

Quizplus · Accepted Answer

Secondary sex characteristics are the physical changes that occur during puberty, such as the growth of facial hair, deepening of the voice, and muscular development. These changes are not directly related to reproduction but are instead related to the development of sexual characteristics associated with being male or female. Primary sex characteristics, on the other hand, refer to the physical structures that are directly involved in reproduction, such as the testes in males and ovaries in females. Static and dynamic are not terms used to describe sex characteristics.
