Answer:

a. activation of the sympathetic autonomic nervous system by the new experience.

Explanation:

The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.

REY [17]

Answer:

The products have less potential energy than the reactants

Explanation:

Potential Energy is energy that can be stored in a physical system and has the ability to be transformed into kinetic energy. Potential energy is the name given to the form of energy when it is 'stored', ie it can at any time manifest itself as chemical reactions, where energy is released as a result of the work done by the reaction. . Thus, the reaction product will have less potential energy than the reactants, an example of this is the reaction described in the question above.
