← Nature & AnimalsWhich effect results when prolonged cold exposure causes peripheral vasodilation in arctic foxes?
A)Localized frostbite in extremities✓
B)Increased core body temperature
C)Enhanced insulation from piloerection
D)Reduced metabolic heat generation
💡 Explanation
During prolonged cold, periodic vasodilation occurs to prevent tissue damage due to freezing via brief warming, but increased heat loss at periphery makes extremities vulnerable. Therefore frostbite risk results, rather than core temperature increase, increased insulation, or reduced metabolism, caused by opposing regulatory processes.
