Question 4.
Explain the concept of negative feedback and how it helps to maintain homeostasis.
Correct Answer: 1- The effect or increased level of the hormone acts to shut
down the con!nued release of the hormone. 2- The brain is constantly
monitoring hormone levels to keep levels within a certain range or set-point
(homeostasis). Nega!ve feedback is a way of "turning off" hormone produc!on
when the desired level is achieved
Question 5.
Explain the concept of positive feedback. Give an example of a hormone that works

Correct Answer: 1- Positive feedback is the action of a hormone increasing the

oxytocin.
