← Nature & AnimalsWhich risk notably increases when a hibernating groundhog experiences intermittent arousals during unusually warm winter periods?
A)Depletion of stored fat reserves✓
B)Increased susceptibility to bacterial infection
C)Impaired cognitive function upon emergence
D)Elevated risk of spontaneous combustion
💡 Explanation
When hibernating animals experience frequent arousals, metabolic rate surges due to shivering thermogenesis because the animal tries to revert to homeothermy, rapidly depleting the finite energy stored as fat. Therefore, depletion of fat reserves is increased, rather than infection, cognitive impairment, or combustion, which involve pathogen exposure, neural disruptions, or highly unusual reactions.
