EVERYDAY SCIENCE

Detailed explanation-1: -All living things exhibit “homeostasis, ” which is the ability to maintain a steady internal environment regardless of their external environment. For example, most humans maintain a body temperature of 98.6 degrees Fahrenheit regardless of whether they are out playing in the snow or hiking in the hot desert.

Detailed explanation-2: -In homeostasis, an organism maintains a constant state relative to the external environment. One example of homeostasis is the way humans maintain a stable body temperature even when the outside temperature changes. A cell is the smallest basic unit of life that maintains homeostasis (Fig. 1.4).

Detailed explanation-3: -Living Things Must Maintain Homeostasis. Homeostasis means “steady state”. Homeostasis is the tendency of an organism or cell to maintain a constant internal environment. Living things constantly adjust to internal and external changes.

Detailed explanation-4: -Examples of homeostasis include the regulation of body temperature, and the balance between acidity and alkalinity. It is a process that maintains the stability of the organism’s internal environment in response to fluctuations in external environmental conditions.

Detailed explanation-5: -All living things grow and develop. All living things are capable of reproduction, the process by which living things give rise to offspring. All living things are able to maintain a constant internal environment through homeostasis.
