Which outcome occurs when deep-diving seals experience extreme cold?

💡 Explanation

Shivering thermogenesis increases muscle activity to produce heat because muscle contractions cause metabolic activity that warms the seal's core. This helps combat hypothermia in frigid waters; therefore shivering is essential, rather than heat loss from vasodilation.
