ANATOMY

Detailed explanation-1: -Organisms need to detect and respond to changes in their internal and external environment. This is because the conditions inside our body must be carefully controlled for it to function effectively and survive. The control systems that allow organisms to respond to changes are incredibly important.

Detailed explanation-2: -Organisms respond to external stimuli to maintain homeostasis. Every organism has its own range of tolerance. When an environmental condition (such as temperature) goes above or below an organism’s optimal range, the organism experiences stress and responds to the stimulus.

Detailed explanation-3: -Homeostasis helps animals maintain stable internal and external environments with the best conditions for it to operate. It is a dynamic process that requires constant monitoring of all systems in the body to detect changes, and mechanisms that react to those changes and restore stability.

Detailed explanation-4: -Homeostasis is the ability of an organism to regulate its internal environment. 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.
