← Nature & AnimalsWhich physiological outcome directly results when a hibernating groundhog experiences peripheral vasodilation during arousal?
A)Rapid body temperature increase✓
B)Suppressed metabolic oxygen demand
C)Elevated skeletal muscle shivering
D)Reduced brown adipose tissue activity
💡 Explanation
When a hibernating groundhog experiences peripheral vasodilation during arousal, increased cutaneous blood flow causes rapid body temperature increase because heat readily transfers to extremities. Therefore rapid body temperature increase results, rather than metabolic suppression, shivering or suppressed BAT activity, which oppose arousal.
