Which outcome occurs when a mammal in a cold environment undergoes peripheral vasodilation beyond a critical threshold?

💡 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.
