In your own words, describe what homeostasis is, using the example of body temperature.

Homeostasis is a biological concept that refers to the body's ability to maintain a stable internal environment despite changes in external conditions. This is crucial for the body's survival and functioning.

Take body temperature as an example. The human body needs to maintain an internal temperature of around 37 degrees Celsius (98.6 degrees Fahrenheit) for optimal functioning. If the external temperature is very cold, the body will respond by shivering to generate heat and maintain this internal temperature. If the external temperature is very hot, the body will sweat to cool down and prevent overheating.

This process of adjusting to temperature changes to maintain internal stability is an example of homeostasis. It's a continuous process and is regulated by the nervous and endocrine systems.
