Question

a student walks to school in the morning when the outside temperature is 60°f. when the same student walks home school, the outside temperature has dropped to 35°f. how would the students body maintain homeostasis? a the students heart rate drops as a negative feedback mechanism to deliver less oxygen to the lungs. b the student begins to sweat as a positive feedback mechanism to reduce the core body temperature. c the student begins to shiver as a negative feedback mechanism to increase the core body temperature. d the students breathing rate slows as a positive feedback mechanism to deliver more oxygen to the lungs.

Explanation:

Homeostasis is the body's ability to maintain a stable internal environment. When the outside temperature drops, the body needs to generate more heat. Shivering is a negative - feedback mechanism where muscle contractions generate heat to increase core body temperature. Sweating is for cooling in warm conditions. A drop in heart rate or breathing rate as described in options A and D are not typical responses to cold for maintaining homeostasis, and they have incorrect feedback - mechanism descriptions.

Answer:

C. The student begins to shiver as a negative feedback mechanism to increase the core body temperature.
