← Nature & AnimalsWhich consequence results when damage impairs lamellar structure?
A)Weakened countercurrent oxygen exchange efficiency✓
B)Increased opercular beat ventilation volume
C)Reduced water salinity gradient production
D)Enhanced diffusion osmotic equilibrium speed
💡 Explanation
Impaired lamellar structure reduces surface area; therefore, countercurrent exchange becomes less efficient because of less contact between blood and water, reducing oxygen uptake rather than increasing water ventilation rate or affecting osmotic capabilities.
