A)positive feedback benefits the organism,whereas negative feedback is detrimental.
B)the positive feedback's responses are in the same direction as the initiating stimulus rather than opposite to it.
C)positive feedback results in increases in some parameter (such as body temperature),whereas negative feedback results only in decreases to the parameter.

Positive feedback systems amplify the response in the same direction as the original stimulus, while negative feedback systems work to counteract the stimulus and bring the system back to homeostasis. Neither type of feedback is inherently beneficial or detrimental; the effects depend on the specific context and outcome. The other answer choices are incorrect; for example, negative feedback can result in increases or decreases to a parameter depending on the situation, and both types of feedback can have control centers.
