How does positive feedback differ from negative feedback?
A) Positive feedback benefits the organism, whereas negative feedback is detrimental.
B) In positive feedback, the effector's response is in the same direction as the initiating stimulus rather than opposite to it.
C) In positive feedback, the effector increases some parameter (such as temperature), whereas in negative feedback
it decreases.
D) Positive feedback systems have effectors, whereas negative feedback systems utilize receptors.
E) Positive feedback systems have control centers that are lacking in negative feedback systems.
