← Nature & AnimalsWhich action occurs when an endotherm experiences hypothermia?
A)Muscle contraction induces shivering thermogenesis✓
B)Increased respiration reduces metabolism
C)Vasodilation promotes heat dispersion
D)Decreased thyroid inhibits heat generation
💡 Explanation
Muscle contraction induces shivering thermogenesis because this mechanism rapidly generates heat by converting ATP into kinetic energy; therefore, core temperature increases, rather than heat loss by dilation and suppressed metabolism during increased respiration.
