Question 1

  1. Positive feedback differs from negative feedback because ________.

    positive feedback is generally beneficial while negative feedback is typically harmful

    positive feedback tends to enhance the triggering stimulus while negative feedback tends to return the body to a homeostatic balance or "ideal" level

    positive feedback is critical to health while negative feedback serves only to alert us to potential health threats

    positive feedback provides moment-to-moment wellbeing while negative feedback causes a cascade effect
