Final answer:

Acclimatization is the process where the body adapts to environmental stresses, like changes in altitude or UV exposure, by altering physiological processes to maintain homeostasis.

Step-by-step explanation:

The process that results in changes in the body in response to environmental stresses such as high or low temperatures, intense ultraviolet radiation from sunlight, or high altitude is called acclimatization. Acclimatization occurs when the body makes adjustments in its physiological processes to maintain homeostasis in a new environment. An example of acclimatization to high altitude is the increase in red blood cell count to compensate for lower oxygen levels, helping ensure sufficient oxygen delivery to tissues. Similarly, exposure to ultraviolet (UV) light can lead to changes such as immune system suppression. Animals also change their coat thickness according to seasonal variations to help regulate body temperature, which is another aspect of acclimatization.
