Mоdule 1 Optiоn A One hiker gets lоst in the desert during the summer аnd is exposed to extreme heаt for severаl hours, while another hiker is trapped in a snowstorm for the same amount of time. Both hikers experience physiological changes as their bodies attempt to maintain a stable internal environment. Using this scenario, explain how homeostasis helps regulate body temperature in extreme conditions. In your response: Define homeostasis and describe its importance. Identify whether body temperature regulation is an example of negative or positive feedback and explain why. Describe how the body’s physiological responses would differ between the hiker in the desert and the hiker in the snowstorm to maintain homeostasis. Option B While hiking in the mountains, David experiences different environmental conditions that challenge his body’s ability to maintain homeostasis. As he climbs to a higher altitude, he notices it becomes harder to breathe. Later, when he takes a break, he realizes he hasn’t eaten much all day and is feeling weak. As the sun begins to set, the temperature drops rapidly, and he starts shivering. Using this scenario, explain how each of the four requirements for human life, oxygen, nutrients, temperature, and pressure, helps maintain homeostasis. In your response: Describe the role of each requirement (oxygen, nutrients, temperature, and pressure) in maintaining homeostasis. Provide specific examples from David’s experience to explain how his body responds to each challenge. Explain why maintaining balance in these conditions is essential for survival.
