← Nature & AnimalsWhich outcome occurs when a basking shark breaches the water surface?
A)Increased oxygen uptake in gills
B)Enhanced epidermal UV radiation absorption✓
C)Accelerated carbon dioxide expulsion
D)Reduced osmotic stress on cells
💡 Explanation
Increased epidermal UV radiation absorption happens because peripheral vasodilation enhances heat gain, therefore boosting the basking shark’s thermoregulation because solar warming exceeds convective heat loss into the cool sea, rather than the listed alternatives.
