Answer

Brief Explanations:

For question 7, the testicles (testes) are the male reproductive organs that produce sperm and secrete male - sex hormones, controlling sperm development. The thyroid is involved in metabolism regulation, the thymus is related to the immune system, and the pineal gland is associated with sleep - wake cycles. For question 8, the prefix "thymo -" can mean shield, as seen in the thymus gland which was named for its shape resembling a shield.
