Final answer:
The two functions of feedback are not solely to teach individuals and punish but rather serve regulatory roles in maintaining homeostasis and responding to physiological changes.
Step-by-step explanation:
The statement that the two functions of feedback are to teach individuals to do better and to punish poor performance is FALSE. In biology, feedback mechanisms pertain to how organisms maintain their internal environments and respond to changes. Negative feedback is a regulatory mechanism that aims to maintain homeostasis by reducing the intensity of a response. For instance, it helps in regulating body temperature and controlling blood glucose levels. Conversely, positive feedback amplifies a response or certain actions, such as during childbirth where the release of oxytocin intensifies contractions. Neither is inherently about teaching or punishment but rather about responding to and managing physiological changes.
