Explain how the body responds to high temperatures to maintain thermoregulation.

When the body temperature rises, the thermoregulatory centre in the brain detects this change. In response, the body undergoes vasodilation, where blood vessels widen to increase blood flow to the skin, and sweating occurs to promote heat loss through evaporation.

This answer is strong because it clearly outlines the physiological processes involved in thermoregulation during high temperatures, demonstrating an understanding of the body's mechanisms for maintaining homeostasis. The question tests the student's ability to apply their knowledge of thermoregulation in a specific context.
