Which effect results when dolphins enter warmer waters after prolonged exposure to freezing seas which triggers increased subcutaneous vasodilation?

💡 Explanation

Heat loss accelerates because vasodilation increases blood flow to the skin surface to modulate internal temperature; therefore, core heat can be rapidly dissipated rather than conserved when in warmer conditions and arteries are expanded.
