Homeostasis is the regulation of an organism’s internal environment to maintain conditions suitable for life. Homeostasis requires
A) competition between the body’s systems.
B) balance between all of the body’s systems.
C) the body’s systems to act independently of each other.
D) maximum growth of all types of cells and tissues within the body.

B) balance between all of the body’s systems.

Explanation: Homeostasis is the regulation or maintenance of a stable internal environment of the body. In achieving homeostasis, all the organs and systems of the body must function harmoniously to maintain a balance.

If balance is not maintained by the organs and systems of the body, a disease or disorder may arise.

Example of homeostasis is the secretion of insulin by the pancreas following a meal to regulate the blood glucose concentration.

this is math not biology xd

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
