Which of the following statements correctly describes the activation of autonomic nervous system function within the circulatory system? a. Sympathetic nervous system activation decreases cardiac output
b. Parasympathetic nervous system activation increases heart rate
c. Sympathetic nervous system activation constricts arteries found within the salivary glands.
d. Parasympathetic nervous system activation constricts arteries found within erectile tissue

Sympathetic nervous system activation constricts arteries found within the salivary glands

Explanation:

The ANS controls the  involuntary contraction of the heart cardiac muscles, glands, intestine,the peripheral resistance of vascular systems, and the rate of pumping of the blood by the heart.

Thus, the ANS system during stressful conditions increases the blood  pressure,heart rate, constrict blood vessels in glands and intestine and dilate the pupils, in anticipation for fight or flight.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
