Question

Homeostatic systems work within minimum and maximum values by using positive feedback to regulate activity above and below a set point.

a-true
b-false

Answer 1

Homeostatic systems use negative feedback to regulate activity above and below a set point.

Step-by-step explanation:

The statement is true.

Homeostatic systems maintain the internal environment of the body within a narrow range. These systems use negative feedback to regulate activity above and below a set point. Negative feedback loops work to bring the variable back within the normal range by reversing a deviation from the set point.

For example, if body temperature rises above the set point, negative feedback mechanisms will initiate processes such as sweating to lower the temperature back to the normal range.
