How does secretion of adrenaline help the body during fear?
Answer and explanation
Correct answer: By increasing heartbeat and energy availability
The governing concept is the emergency, or fight-or-flight, response. During fear, the adrenal glands release adrenaline, which increases heart rate and breathing and helps make more glucose available for rapid energy production. These changes support the muscles and prepare the body for quick action. Therefore A is correct. Adrenaline does not reduce blood sugar to zero, grow roots, or destroy dendrites, so B, C, and D are inappropriate.
