Question

What is homeostasis?


The cell membrane that controls what comes in and goes out of the cell


The process of maintaining a stable environment within the body

Answer 1

Homeostasis is the process of maintaining a stable internal environment within the body despite changes in external conditions. It involves various physiological mechanisms that regulate factors such as temperature, pH, hydration, and the concentration of ions and nutrients. This regulation is crucial for the proper functioning of cells and organs, ensuring that the body operates optimally. The term can also refer to the ability of individual cells to maintain a stable internal environment, often regulated by structures like the cell membrane, which controls what substances enter and exit the cell.
