Childbirth in mammals would be an example of endocrine-controlled negative feedback, because the production of oxytocin during childbirth results in additional oxytocin being synthesized by the posterior pituitary gland.

a. trueb. false

The answer is option a. False.

Explanation:

Childbirth in mammals is not an example of endocrine-controlled negative feedback mechanism. In negative feedback mechanism one of the end product controls the activity of the pathway to stop further release of the product. In the example, the production of oxytocin during childbirth resulted in further synthesis and secretion of oxytocin from the posterior pituitary.

Childbirth in mammals is an example of endocrine-controlled positive feedback mechanism.
