Question

in this activity, you will identify examples of homeostasis and provide evidence that feedback mechanisms maintain homeostasis. the human body uses feedback mechanisms to maintain homeostasis in response to changes in the environment. one example is how the body regulates temperature. scenario: after running outside on a hot day, your body begins to sweat. later, when you go inside an air - conditioned room, you start to shiver. 1. identify whether this is an example of positive or negative feedback and explain your reasoning. please type your answer here

Explanation:

Negative feedback works to reverse changes and restore the body to its normal state. When the body is overheated (from running on a hot day), sweating cools it down. When it's too cold (in the air - conditioned room), shivering generates heat. Both sweating and shivering are responses that counteract the environmental change (temperature change) to bring the body back to its optimal internal temperature (homeostasis). Positive feedback would amplify a change (e.g., in blood clotting, the process of clotting is amplified), but here the responses (sweating and shivering) are reducing the deviation from normal body temperature.

Answer:

This is an example of negative feedback. Negative feedback reverses changes to maintain homeostasis. Sweating cools the body when overheated (from running on a hot day), and shivering warms the body when too cold (in the air - conditioned room), both actions counteract temperature changes to restore normal body temperature.
