← Nature & AnimalsWhich heat loss consequence results when a marine mammal's blubber undergoes vasodilation?
A)Increased core temperature maintenance efforts
B)Elevated basal metabolic oxygen demands
C)Decreased thermal insulation effectiveness✓
D)Reduced peripheral vasoconstriction efficiency
💡 Explanation
Increased blood flow to the subcutaneous fat layer, via vasodilation, increases convective heat transfer, therefore lowering the blubber's effective insulation, rather than aiding in insulation since more thermal energy escapes.
