← Nature & AnimalsWhich effect occurs when a mammal experiences prolonged exposure to high temperatures leading to cutaneous vasodilation?
A)Increased metabolic rate and energy expenditure
B)Enhanced insulation from subcutaneous fat reduction
C)Decreased core body temperature via convection✓
D)Suppressed shivering and brown fat activity
💡 Explanation
When exposed to heat, mammals undergo cutaneous vasodilation, which is the widening of peripheral blood vessels, increasing heat dissipation via convection. Therefore, decreased core body temperature results, rather than increased metabolism, enhanced isulation or suppressed shivering as they are involved in heat genereation or retension.
