← Nature & AnimalsWhich outcome occurs when a mammal in a cold environment undergoes peripheral vasodilation beyond a critical threshold?
A)Increased core body temperature stability
B)Shift towards anaerobic metabolism
C)Accelerated core heat loss to environment✓
D)Enhanced shivering-based heat production
💡 Explanation
When peripheral vasodilation surpasses a limit in cold conditions, heat transfer occurs via conduction because blood vessels at skin surface widen, dissipating heat rapidly. Therefore, core heat loss accelerates, rather than temperature stability, anaerobic metabolism, or enhanced shivering, requiring vasoconstriction to insulate the core.
