← Nature & AnimalsWhich outcome happens when arctic fox metabolic rate drops suddenly?
A)Skeletal muscle shivering induces thermogenesis✓
B)Decreased vasodilation promotes heat dissipation
C)Countercurrent exchange generates ATP faster
D)Epinephrine restricts unnecessary bodily functions
💡 Explanation
Shivering initiates because rapid core temperature decline activates muscle motor neurons, causing rhythmic contractions through shivering thermogenesis; therefore, heat is rapidly produced, rather than vasodilation dissipating heat during hypothermia.
