In male children, the testes

a) contain spermatogonia that are capable of replicating.
b) contain cells that actively undergo mitosis through the male's entire life span.
c) are inactive until puberty.
d) A and B
e) A and C

To determine the answer to this question, we need to review the characteristics and functions of the testes in males.

The testes are the primary reproductive organs in males responsible for the production of sperm.

Option a) states that the testes contain spermatogonia that are capable of replicating. Spermatogonia are the precursor cells of sperm, and they undergo a process called mitosis to replicate and produce more spermatogonia. This process, known as spermatogenesis, begins during fetal development and continues throughout a male's life.

Option b) claims that the testes contain cells that actively undergo mitosis through the male's entire life span. This is incorrect because it is only the spermatogonia that divide via mitosis in the testes, not all the cells present in the testes.

Option c) suggests that the testes are inactive until puberty. This is also incorrect because although the testes are not fully functional before puberty, they do produce small amounts of testosterone and are involved in the early stages of spermatogenesis.

Therefore, the correct answer is e) A and C. The testes do contain spermatogonia capable of replicating (option a) and are relatively inactive until puberty (option c).
