Which thermal consequence results when a hibernating bear's skin undergoes vasodilation during an arousal phase?

A)Heat loss exceeds metabolic heat production✓

B)Brown fat metabolism becomes less effective

C)Core temperature drops below vital minimum

D)Shivering intensifies throughout musculature

💡 Explanation

When a hibernating bear undergoes vasodilation in surface vessels, heat transfer to the environment increases via convection because blood flow to periphery rises, counteracting conservation. Therefore heat loss exceeds metabolic production, rather than maintaining core temperature/triggering BAT/inducing shivering, each needing differing conditions.
