The layer of fat beneath the skin of mammals helps control temperature by
Correct answer: C. insulating the body against heat loss
- A. producing heat through metabolism
- B. increasing blood flow to the surface
- C. insulating the body against heat loss
- D. absorbing sunlight
Explanation
Subcutaneous fat conducts heat poorly, so it keeps core warmth in, which is why marine mammals carry thick blubber. Generating heat is the job of metabolism in liver and muscle, not of fat.

About Kidney and Urinary System
The kidney and urinary system remove nitrogenous wastes, regulate water and ion balance, and help maintain blood pH through filtration, selective reabsorption and secretion. Questions cover nephron structure, ultrafiltration, the loop of Henle, collecting ducts, urine formation and the roles of ADH and aldosterone, while distinguishing excretion from egestion.
