Plant Adaptations - Test Corrections

When specialized cells in the pancreas detect that blood sugar levels are too high, they stimulate the release of insulin into the blood to lower the blood sugar levels. How does this help the body maintain homeostasis?

• To decrease the body temperature

• To increase the amount of sugar in the blood

• To increase the volume of water in the blood

• To return the blood sugar levels back to a normal level
