← Nature & AnimalsWhich outcome occurs when deep-diving seals experience extreme cold?
A)Increased internal heat generation through shivering✓
B)Peripheral vasodilation warms extremities directly
C)Reduced metabolic rate enhances oxygen conservation
D)Glucose production increases brain thermal output
💡 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.
