Question

which of the following is not an example of a homeostasis? single celled organisms that live in water have contractile vacuoles that constantly pump water out of the cell to ensure the correct water concentration in the cell. cells must remain the same size. humans must maintain a body temperature of 98.6f to ensure that chemical reactions can occur. enzyme require a specific ph to work properly. rewatch

Explanation:

Homeostasis is the ability to maintain a stable internal environment. Single - celled organisms pumping water to maintain water concentration, humans maintaining body temperature for chemical reactions, and enzymes requiring a specific pH are all examples of homeostasis. Cells do not necessarily have to remain the same size as a part of homeostasis; cell size can change depending on various physiological processes.

Answer:

Cells must remain the same size.
