The secretion of of hormone a causes an increase in activity x in an organism. if this mechanism works by positive feedback, which of the following statements represents that fact?
a. an increase in x produces an increase in a
b. an increase in x produces a decrease in a
c. a increase in a produces an increase in x.
d. a decrease in a produces an increase in x.
e. both a and c are correct.

E. is the correct answer

Explanation:

C. An increase in A produces an increase in X.

This statement can be directly concluded from the description of the effects of hormone A on the activity of X in the problem.

A. An increase in X produces an increase in A

This statement can be concluded from the fact that A and X work in a positive feedback mechanism.

In a positive feedback mechanism, a stimulus produces a response (secretion of hormone A) which has an effect (increase in X) that increases the original stimulus. A cycle is created, in which secretion of A causes an increase of X, and the increase of X causes an increased secretion of A.

To shut off the positive feedback cycle, an outside factor is required.
