Question

The human body can regulate in different ways. For example, negative feedback occurs when body temperature begins to rise and the body reacts by sweating. Another example is positive feedback when the human stomach secretes the inactive enzyme pepsinogen, which is converted to the active enzyme pepsin. This then triggers a process that helps convert more pepsinogen into pepsin. Considering these examples, which of the following is the major difference between negative and positive regulatory systems in human anatomy?

A. Negative regulatory systems counteract the change, while positive systems amplify the change.

B. Negative regulatory systems are harmful to the organism, while positive systems are beneficial.

C. Positive regulatory systems are physiological, while negative systems are metabolic.

D. Positive regulatory systems utilize active energy, while negative systems utilize passive energy.

Answer 1

answer a is right maybe because option b is wrong none of them are given harmful or beneficial in the text while third is completely wrong because both are metabolic and last one there is given that positive feedback secrets the inactive energy not active so
