Answer:
(B). inhibiting HMG-CoA reductase.
Explanation:
Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.
It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.
Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.
Thus, the correct answer is option (B).

Answer:
Spermatogenesis , Spermatogonia
Explanation:
Gonads are the primary sex organs in the male which are the two testes.
Each testis divide into testicular lobules each containing the sparse connective tissue with the endocrine interstitial cells that secrets testosterone, and also contains one to four highly convoluted seminiferous tubules which is responsible for sperm production.
The process is known as <u>spermatogenesis</u>.
This process begins with mitotic division of stem cells which are located close to basement membrane of tubules. The cells are known as <u>spermatogonial stem cell</u>s. The division produces two types of cells.
Type A cells are the cells which replenish stem cells and type B cells are the cells which differentiate into spermatocytes. They have number of chromosomes = 46.
