Answer 1

1. Hans Selye
2. General Adaptation Syndrome (GAS)
3. After the body recognises a stressful stimulus during the Alarm-Reaction stage, the adrenal pituitary cortex activates and releases hormones to prepare for a fight-or-flight reaction. Cortisol is released during this stage to control the stress response. During the resistance stage, the body prepares to reduce hormone levels, heart rate, and blood pressure. Cortisol provides glucose and energy to fight extended stress.
