the answer is option A and not B
hormones can affect more that one target organ but responses to hormones are involuntary
Greetings, The Myschool Team.
The correct answer is A(Their responses are voluntary) and not B(They may affect more than one target organ). This is due to the fact that hormones are secreted into the bloodstream and have the potential to affect more than one organ. Adrenaline for example affects the eyes, heart, muscles, lungs, liver, e.t.c. Testosterone, Growth hormone and Estrogen equally have effects on several organs. However, it is absolutely true that responses to hormones are involuntary. Therefore, the correct answer is A. Thank you.
