Which outcome occurs when beaver's tail temperature rises significantly during physical activity in cold water?

💡 Explanation

Increased tail temperature triggers vasodilation, leading to increased blood flow from the tail’s surface and reducing thermal insulation, because heat escapes more efficiently. This therefore reduces thermal skin insulation, rather than retaining arterial heat due to its role in the heat dissipation.
