Positive feedback differs from negative feedback in that:

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.

D. positive feedback systems have control centers that are lacking in negative feedback systems.

C. Positive feedback results in increases in some parameter (such as body temperature), whereas negative feedback results only in decreases to the paramenter

Explanation:

Positive and negative feedback are essential to the body's homeostasis, or to maintain balance and regulate the internal environment of organisms; that is to say, they are important for the organisms to self-regulate themselves. Positive feedback is in the same direction as the initiating stimulus as they amplify the original stimulus. Positive feedback leads to an increase in a reaction, thus amplifying the effects of a reaction. However, negative feedback decreases a reaction; negative feedback stabilizes the system.
