B. is most commonly restored by negative feedback mechanisms

The role of the effector in any negative feedback situation is to: A. continue the effects of the stimulus B. enhance the imbalance C. restore balance through inhibition of the stimulus D. increase the stimulus E. restore balance through the sensory receptors
