Question

1. describe what is happening in the above diagram.

Explanation:

The diagram shows a homeostatic temperature - regulation process. On the left, a person is sweating (indicating high body temperature). The brain (with a temperature - related area) receives a signal of high temperature (from the red thermometer with an upward arrow). Then, on the right, the person is in a cold environment (with ice - like symbols and shivering), and the brain receives a signal of low temperature (from the blue thermometer with a downward arrow). The brain processes these temperature signals and initiates responses (sweating to cool down when hot, shivering to warm up when cold) to maintain a stable internal body temperature.

Answer:

The diagram depicts the body's temperature - regulation (homeostasis) process. When the body is hot (left: sweating, red thermometer up), the brain receives the high - temperature signal. When the body is cold (right: shivering, ice symbols, blue thermometer down), the brain gets the low - temperature signal. The brain then triggers responses (sweating to cool, shivering to warm) to keep body temperature stable.
