Module 1 – Set 1 Select A or B A hiker gets lost in the desert during the summer and is exposed to extreme heat for several hours, while another hiker is trapped in a snowstorm for the same amount of time. Compare how the body’s physiological responses would differ in these extreme conditions. During a fever, the body raises its internal temperature to fight off infection, creating a cycle that continues until the threat is eliminated. This is an example of positive feedback. In contrast, when you overheat on a hot day, your body cools itself by sweating, an example of negative feedback. Compare and contrast these two processes, explaining how positive and negative feedback contribute to maintaining or disrupting homeostasis. Use the examples provided in your answer.
