Answer to Question 1

Selye theorized that the body goes through several stages in response to sustained stress. The first phase is a type of alarm response to immediate danger or threat. With continuing stress, we seem to pass into a stage of resistance, in which we mobilize various coping mechanisms to respond to the stress. Finally, if the stress is too intense or lasts too long, we may enter a stage of exhaustion, in which our bodies suffer permanent damage or death. Selye called this sequence the general adaptation syndrome (GAS).
The physiological effects of the early stages of stress, in particular its activating effect on the sympathetic nervous system, mobilizes our resources during times of threat or danger by activating internal organs to prepare the body for immediate action, either fight or flight. These changes increase our strength and mental activity.
