question 1 - 18
all of the following are symptoms of not getting enough sleep except
o irritability.
o alert and energetic.
o trouble concentrating.
o falling asleep during class.

Explanation:

When a person doesn't get enough sleep, they are likely to be irritable (due to hormonal changes and stress), have trouble concentrating (as the brain needs sleep for proper cognitive function), and may fall asleep during class (extreme drowsiness). However, being alert and energetic is the opposite of what occurs when sleep - deprived.

Answer:

alert and energetic.
