Question

which of the following is a symptom of hypoglycemia? high energy shakiness mental alertness slow heart rate

Explanation:

Hypoglycemia is low - blood sugar. It often causes the body's sympathetic nervous system to activate, leading to symptoms like shakiness. High energy is not typical as glucose is low. Mental alertness is usually impaired, not enhanced. A slow heart rate is not a common symptom; rather, a rapid heart rate can occur due to sympathetic activation.

Answer:

Shakiness
