I need help in these question. Can u please help me? The best answers win. Thank YOU!!!!

1. What processes take place in the human body to prevent it from overheating during execise? (Explain two.)

2. Isaac went to school with a cold. Several days later half of his classmates also had colds. Explain how it is possible that some students had clods but others did not.

Answer 1

1- a) Sweating: When sweat evaporates from the skin it helps in dropping the body temperature to normal.

    b) Heavy breathing: Extra accumulating heat inside the body is transferred outside with the exchange of gases.

2- I think the correct answer would be the fact that only classmates caught cold that had close interaction with Isaac.Others that did not were prevented from catching the cold.
