Detailed explanation-1: -These are the fight or flight responses triggered by our amygdala. These responses saved us from danger as early humans and they save us from danger today. So, they are very helpful and adaptive when it comes to life-threatening situations.

Detailed explanation-2: -Similar to the flight/fight response, a freeze response is believed to have adaptive value.

Detailed explanation-3: -Muscles tense and beads of sweat appear. This combination of reactions to stress is also known as the “fight-or-flight” response because it evolved as a survival mechanism, enabling people and other mammals to react quickly to life-threatening situations.

Detailed explanation-4: -The perception of threat activates the sympathetic nervous system and triggers an acute stress response that prepares the body to fight or flee. These responses are evolutionary adaptations to increase chances of survival in threatening situations.
