    Which of the following applies to both the nervous system and the endocrine (hormonal) system?

    0

    Explanation

    The correct answer is H.

    All statements are correct. Both nervous and hormonal systems maintain a constant internal environment, hence they are homeostatic processes. Nervous systems use neurotransmitter chemicals in synapses, whereas hormonal systems use hormones as chemical messengers in the blood. Nervous responses are either voluntary (use the brain) or involuntary (do not use the brain), whereas hormonal responses are always involuntary, but are activated through detection in the brain.
