Answer to Question 1

D
Feedback:
Learning begins as an electrical circuit called an engram, a reverberating circuit of action potentials that eventually becomes a long-term, permanent memory in the presence of the proper neurotransmitters and hormones.

Answer to Question 2

A, D, E
Feedback:
Decreasing sympathetic response would reduce the stress response, whereas increasing parasympathetic response would have the same effect. Although not optional, a medication that slowed down the entire nervous system would also work. In many areas, the parasympathetic nervous system works in opposition to the sympathetic nervous system (SNS). This allows the autonomic system to maintain a fine control over internal homeostasis. For example, the SNS increases heart rate, whereas the parasympathetic nervous system decreases it. Thus, the autonomic nervous system can influence heart rate by increasing or decreasing sympathetic activity or by increasing or decreasing parasympathetic activity.
