← Nature & AnimalsWhich risk increases when a hibernating bear's metabolic rate rises significantly?
A)Premature arousal from hibernation state✓
B)Increased efficiency of lipolysis
C)Enhanced heat production via diffusion
D)Reduced urea excretion rate
💡 Explanation
Premature arousal occurs due to thermogenesis exceeding the critical threshold temperature; because endogenous rhythms shift their set points via non-shivering thermogenesis, specifically uncoupling protein 1 (UCP1), causing disruption, therefore, the metabolic demand goes outside survivable bounds, rather than remaining suppressed.
