The answer is the fourth one: the maintenance of a relatively constant internal environment within the body despite changes in the external environment.

Explanation for each option:

  1. The combination of growth, self-repair and energy release: This option describes various biological processes but does not specifically define homeostasis. Homeostasis is more about maintaining stability rather than growth or energy release.

  2. The combination of anabolic and catabolic reactions inside the body: While anabolic and catabolic reactions are part of metabolism, which contributes to homeostasis, this option does not capture the essence of homeostasis itself, which is about maintaining internal balance.

  3. The production of energy inside the cells: This describes cellular respiration or energy metabolism, which is a part of maintaining homeostasis, but it is not the definition of homeostasis.

  4. The maintenance of a relatively constant internal environment within the body despite changes in the external environment: This is the correct definition of homeostasis. It refers to the body's ability to regulate its internal environment to maintain a stable, constant condition, such as temperature, pH, and electrolyte balance, despite external changes.

In summary, homeostasis is about maintaining internal stability in the face of external changes, making the fourth option the correct definition.
