The storage of fats below skin and erection of hairs on skin occurs during:
Correct answer: C. Cold temperature
- A. Normal temperature
- B. Hot temperature
- C. Cold temperature
- D. None
Explanation
During cold temperatures, the human body employs several mechanisms to conserve heat and maintain internal body temperature, a process known as thermoregulation. Two such mechanisms are the storage of fats below the skin, which provides insulation, and the erection of hairs on the skin, which traps air and creates an insulating layer. These adaptations help the body retain heat. In contrast, normal and hot temperatures do not require such responses as the body's focus shifts to maintaining or dissipating heat, respectively. Therefore, the correct answer is cold temperature.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
