← Nature & AnimalsWhich outcome commonly results when aquatic mammals transition to land environments?
A)Increased muscle contraction for thermogenesis✓
B)Reduced density of specialized insulation
C)Enhanced cutaneous respiration efficiency
D)Decreased metabolic rate in tissues
💡 Explanation
An amphibious mammal experiences conductive heat loss; thus *shivering thermogenesis* increases internal heat production through muscle contractions. This provides heat because metabolism rises, therefore combatting the greater cooling rates, rather than lowering metabolism.
