Sweating __________.

• A. can be prevented by drinking adequate amounts of water
• B. happens only on hot days
• C. is a major thermoregulatory mechanism in dogs
• D. results in irreversible dehydration
• E. helps the body thermoregulate

Answer: (E)

Verified step by step guidance

1. Understand the concept of thermoregulation: Thermoregulation is the process by which an organism maintains an optimal body temperature, even when the surrounding temperature is different.
2. Identify the role of sweating in thermoregulation: Sweating is a physiological response that helps cool the body through the evaporation of sweat from the skin surface, which removes excess heat.
3. Evaluate the options given: Consider each option and determine if it accurately describes the role of sweating in thermoregulation.
4. Option analysis: Drinking water does not prevent sweating; it replenishes fluids lost through sweating. Sweating can occur in various conditions, not just on hot days. Dogs primarily use panting, not sweating, for thermoregulation. Sweating does not cause irreversible dehydration; it is a reversible process if fluids are replenished.
5. Conclude with the correct understanding: Sweating helps the body thermoregulate by cooling it down through the evaporation of sweat, which is the correct answer.
