Which outcome occurs when a fish's swim bladder loses its gas permeability due to tissue damage?

A)Increased buoyancy at greater depths
B)Reduced ability to maintain neutral buoyancy
C)Enhanced oxygen absorption from the water
D)Improved temperature regulation in cold water

💡 Explanation

When the swim bladder loses gas permeability, diffusion cannot adjust buoyancy because the bladder controls gas exchange to maintain hydrostatic equilibrium, leading to inability for the to maintain its vertical position in the water column. Therefore a reduced ability results, rather than any other options which would happen under differing physiological processes.
