Select the correct answer.
kaheart [24]

Answer:

The answer is letter A, sleepiness.

Explanation:

The "Fight-or-Flight Response" is a <em>response of an organism to stress.</em> When this happens, the body shows several signs and symptoms which involve <em>cool and pale skin, sweating, dry mouth, dilated pupils, etc.</em>

Under stress, the body releases a hormone called "adrenaline." <em>This hormone is responsible for a temporary heart rate increase. </em>

<em>The breathing or respiratory rate also increases.</em> This is the body's coping mechanism in order to<em> increase "oxygen" intake</em>. <u>The oxygen is used by the muscles as a preparation to fight or flee from the situation.</u>

Thus, letter A is the only incorrect effect of the fight-or-flight response.
