Final answer:
True, a positive feedback loop escalates a change in the body's status to push the system further out of homeostasis until a specific endpoint is reached, exemplified by childbirth and blood clotting.
Step-by-step explanation:
The statement is true: a positive feedback loop results in a change in the body's status, rather than a return to homeostasis. Unlike negative feedback, which maintains equilibrium, positive feedback amplifies a physiological response until a specific endpoint is reached.
This escalates the deviation from the normal state rather than reversing it. For instance, during childbirth, the release of oxytocin leads to stronger uterine contractions, which in turn promotes more oxytocin release, intensifying the labor process until the baby is born. Similarly, positive feedback loops also regulate blood clotting, where the initial clotting signal leads to additional clotting until the bleeding stops.
