Final answer:
Homeostasis refers to the body's ability to maintain a constant internal environment, like temperature, to ensure proper function despite external changes. This process is crucial for survival in both humans and other organisms that exhibit adaptations to handle environmental challenges.
Step-by-step explanation:
The human body regulates its internal temperature around 98.6 degrees Fahrenheit, which is an example of homeostasis. Homeostasis is the process by which living things maintain a stable internal environment despite changes in external conditions. This characteristic is vital for the survival and function of all living organisms. For instance, when you are cold, your body initiates shivering to generate heat, and when you are hot, you sweat to cool down through evaporation. These responses illustrate how the body maintains its internal temperature, an aspect of homeostasis.
Examples of Homeostasis
A further example of homeostasis in action is seen on a hot day when you sweat: your body is releasing heat to cool down and sustain its core temperature. In another context, desert plants and animals showcase specific adaptations, like the ability to retain water or reflect sunlight, to survive extreme temperatures. These adaptive traits have evolved to maintain homeostasis in harsh conditions.
