To maintain homeostasis, the human body has evolved feedback loops. A feedback loop is the cycle between the input (change), your body, and the output (your body’s reaction). The maintenance of body temperature, pH, blood sugar, and hydration are controlled by ________ feedback loops, where your body reverses a change in its environment to keep internal levels at a set point.

• Positive

• Negative

• Neither A or B
