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).
The correct answer for this question is Osmosis.
Osmotic diuresis is an increase in urine production brought on by the presence of specific chemicals in the tiny kidney tubes. When chemicals like glucose enter the kidney tubules and cannot be reabsorbed, excretion takes place (due to a pathological state or the normal nature of the substance). The compounds raise the osmotic pressure inside the tubule, which causes water to be retained in the lumen and inhibits water absorption, boosting urine production (i.e., diuresis). Therapeutics like mannitol, which is used to improve urine output and decrease extracellular fluid volume, have the similar effect.
By making the blood more osmolar, substances in the circulation can also increase the volume of fluid flowing through the body.

Answer:
Homeostasis can be defined as the natural mechanism of the body by which the internal temperature of the body is maintained.
This phenomenon is important for the normal metabolism and functioning of the body.
Whenever the body encounters any change in the outer environment, the body tries to cope up with the conditions by maintaining a proper internal temperature inside the body.
Example: shivering of body is a normal response during cold environment to maintain the internal temperature of the body.
