Which of the following is/are true regarding feedback mechanisms in homeostasis? select ALL that are TRUE In Positive feedback, responses increase deviation away from a constant regulated set-point. In feedback regulation, a physiological variable is maintained at a regulated set-point, by negative feedback responses initiated when the variable is greater than the set- point, and by positive feedback responses initiated when the variable is less than the set-point. In negative feedback, a homeostatic system monitors conditions that could influence a regulated variable, and initiates responses that prevent change of this variable away from a regulated set-point. In negative feedback, responses that influence a regulated variable are initiated when the variable deviates from a set-point, and end when the variable returns to this set- point. In negative feedback, responses that maintain a regulated variable are initiated when the variable matches a set-point, and end when the variable deviates from this set- point. Positive feedback stimulates body systems, while negative feedback shuts down body systems. In negative feedback, responses maintain a variable at a constant regulated set-point, and prevent deviation from this set-point. Negative feedback is harmful to the body, while positive feedback is beneficial.
