Which thermoregulatory consequence arises when a mammal's skin temperature drops substantially in frigid conditions?

💡 Explanation

Vasoconstriction causes reduced blood flow, minimizing heat loss to the peripheral skin rather than vasodilation. This occurs because heat is retained by minimizing conductive heat loss, therefore preventing hypothermia over the short-term, rather than shivering which demands much energy.
