Which outcome occurs when a mammal uses vasodilation at high altitude?

💡 Explanation

At high altitudes, vasodilation near the skin surface increases blood flow, therefore the higher skin temperature decreases risk of frostbite because of the warm blood flow near the skin, rather than reducing heat loss which would happen in a warmer environment.
