Question

Living organisms are only able to function and thrive if they can maintain constant or stable internal conditions. This ability is known as _______.

Answer 1

The ability of organisms to regulate and thus maintain a relatively stable internal environment, despite external pressures, is called HOMEOSTASIS. This word comes from two Latin/Greek root words: "homeo" and "stasis".
"Homeo" means constant or unchanging. And "stasis" or "static" refers to stillness, non-movement. So, together, we can translate Homeostasis into a constant stillness inside, which makes sense for "maintaining normal internal states."

Answer 2

Answer:

Homeostasis

Explanation:

refers to the necessity of an organism to maintain constant or stable internal conditions.

In order to maintain homeostasis, organisms must have structures and processes that allow them to respond to stimuli. For example, the cell membrane is a structure that allows cells to maintain the proper concentration of materials inside and outside of a cell, so the organism that contains the cell can function properly.
