Question

Which is an example of the body maintaining homeostasis using a positive feedback loop? While exercising, the body heats up and releases sweat to decrease the body’s temperature. After not eating, the body sends signals to the brain to stimulate the feeling of hunger. During childbirth, the body releases chemicals to promote the process until the child is born. When losing balance, the body senses the position of the head and sends signals to keep balance.

Answer 2

In a positive feedback loop, signals are sent to amplify the disturbance and move away from its previous equilibrium state. Therefore, the best choice is the 3rd, where during childbirth, the body releases chemicals to promote the process.
All other choices involve negative feedback loops, where the body acts to return to its previous state.
