← Nature & AnimalsWhich outcome occurs when a marine mammal has diminished adipose (fat) layers during intense muscular activity?
A)Increased convective heat loss to water✓
B)Increased metabolic heat production through shivering
C)Reduced vasoconstriction in peripheral tissues
D)Enhanced countercurrent heat exchange efficiency
💡 Explanation
Convective heat loss increases because diminished adipose layers impair insulation, thus enhanced vasodilation releases more heat into the surrounding water. This occurs especially after exertion causing extreme heat production, therefore less insulating fat leads to more significant unregulated transfer, rather than the conservation seen in controlled heat exchange.
