Which outcome reduces heat loss when a beaver is submerged in icy Arctic waters?

💡 Explanation

Peripheral vasoconstriction minimizes heat loss at extremities because reduced blood flow limits convective heat transfer into the icy surround; therefore, core temperature remains stable, rather than dropping via conduction through blood.
