Answer to Question 1

Ans: B
The sympathetic response associated with anxiety that leads to piloerection and sweating results from norepinephrine. Acetylcholine has no effect on the pilomotor muscles and sweat glands. Serotonin plays a role in the control of appetite, sleep, and mood states. Histamine controls gastric secretions and the smooth muscle of the gastrointestinal tract.

Answer to Question 2

Ans: A
Melatonin is classified as a neuropeptide. Serotonin is classified as a biogenic amine. Glutamate and gamma-aminobutyric acid are amino acids.
