Question

deep inside the emotional center of the brain, an almond - shaped structure called the amygdala is working hard. if someone is faced with a bully, the amygdala sends out alarms. it tells the body, \time to go into crisis mode!\ the chemicals epinephrine and norepinephrine are released into the bloodstream. everything speeds up, including heartbeat, blood flow, and breathing. next, the hormone cortisol is sent on an emergency mission to fill the muscles with nutrients and energy in case anyone needs to run. -- \bullying and stress\ which chemical helps supply the muscles with energy when the body faces a crisis, such as confronting a bully?

• cortisol
• amygdala
• epinephrine
• norepinephrine

Explanation:

To solve this, we analyze the text:

• The amygdala is a brain structure, not a chemical, so eliminate the "amygdala" option.
• Epinephrine and norepinephrine are released to speed up processes like heartbeat and blood flow.
• The text states that "the hormone cortisol is sent on an emergency mission to fill the muscles with nutrients and energy in case anyone needs to run". So cortisol is the chemical that helps supply muscles with energy during a crisis like confronting a bully.

Answer:

A. cortisol
