Answer 2

Answer:  

In mammals, the testis is enclosed by the scrotum.  

Explanation:  

Testicles or testis is the sperm and androgen producing organ in animals. It forms a part of the male reproductive system and has two core functions – production of sex hormones and the creation of sperm.  

In mammals, the scrotal sac maintains the temperature of the testicles at a distinctly lower degree than the body that is required for spermatogenesis.
