What type of interaction promotes homeostasis?

Negative feedback
Positive feedback
Enzyme/Coenzyme interaction
Ion exchange

The correct answer is: Negative feedback

Homeostasis is the process by which the body maintains a stable internal environment. Negative feedback is a type of interaction that promotes homeostasis by reducing or reversing any changes from the body's set point. This ensures that the body's internal conditions, such as temperature or blood sugar levels, remain within a normal range. The other options, positive feedback, enzyme/coenzyme interaction, and ion exchange, do not directly promote homeostasis. Positive feedback amplifies changes from the body's set point, which can be harmful if not controlled. Enzyme/coenzyme interaction and ion exchange have specific roles in the body, but they do not play a direct role in maintaining homeostasis. Therefore, they are not the correct answer for this question.
