Nature & Animals

In marine mammals migrating to warmer waters, which adaptation results from insufficient blubber?

A)Increased cutaneous vasodilation and hypothermia
B)Decreased metabolic rate and torpor
C)Elevated shivering threshold and vasoconstriction
D)Enhanced countercurrent peripheral heat exchange

💡 Explanation

Excessive heat loss occurs because the *vasodilation* mechanism attempts to dissipate heat, due to insufficient insulation allowing core temperature to drop; therefore hypothermia results, rather than adaptive strategies like reduced metabolic rate.
