Which of the following is not a change that may be caused by hormonal stimulus?

a- an increase in enzymatic activity

b- a change in membrane potential

c- direct control of the nervous system

d- the stimulation of a genetic event resulting in protein synthesis

option C) Direct control of the nervous system

Explanation:

Hormonal stimulus does ALL except to direct the control of the nervous system. The nervous system is directly controlled by the BRAIN AND SPINAL CORD by the help of nerve impulses NOT hormonal stimulus.

On the other hand, hormonal stimulus brings about

- increase in enzymatic activity

- change in membrane potential

- stimulation of a genetic event resulting in protein synthesis

So, option C is the right option

answer; i believe the correct answer to the above question is ( friction)
