Which outcome occurs when a fish relies solely on diffusion rather than utilizes its swim's bladder?

A)Increased osmotic pressure in tissues
B)Reduced oxygen absorption efficiency
C)Enhanced buoyancy control at depth
D)Decreased metabolic rate sensitivity

💡 Explanation

Reduced oxygen absorption via lungs occurs when the bladder is not inflated due to reduced surface area; therefore, rate decrease occurs rather than improved; because diffusion rate alone cannot fulfil oxygen metabolic demands without a swim bladder.
