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

In positive feedback, the effector's response reinforces the initiating stimulus, resulting in further amplification of the response. In contrast, negative feedback opposes the initiating stimulus, resulting in a decrease or stabilization of the response. However, neither positive nor negative feedback is inherently beneficial or detrimental to the organism, as their effects depend on the context and the specific physiological process involved.
