← Nature & AnimalsWhich outcome occurs when peripheral constriction ceases in mammals adapted to arctic conditions experiencing extreme cold?
A)Increased core heat conservation occurs.
B)Rapid hypothermia quickly develops.✓
C)Peripheral vasodilation warms extremities.
D)Blubber fat layer suddenly insulates.
💡 Explanation
Rapid hypothermia develops with a cessation of peripheral constriction because thermal energy escapes via vasodilation, accelerating heat loss rather than maintaining core temperature. Therefore, the animal spirals towards hypothermia because active heat saving stops, rather than peripheral warming.
