Answer 1

Answer:i.1. Scrotum

2. Vas deferens

3.Epididymis

ii. In seminiferous tubules

iii.Scrotum.

The scrotum acts as a "climate control system" for the testes.

Epididymis

It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization.

iv.

Leydig cells, also known as interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle. They produce testosterone in the presence of luteinizing hormone (LH).
