Answer 1

Please find the answer below:

Answer: B. Create physiological change to scare off predators.

Explanation: Whenever there is a threat or perception of oncoming injury, the body responds by a physiological reaction called the flight or fight reaction or the stress response. Therefore when there is stress the hypothalamus initiates the release of the norepinephrine by the sympathetic nervous system. In addition to this, the adrenal medulla also releases the epinephrine and some amount of norepinephrine to cause the physiological reaction. During the stress response, the heartbeat increases, and more blood rushes to the arms and the legs to prepare the body for the flight or fight response. .
