← Nature & AnimalsWhich mechanism reduces swim bladder buoyancy control in deep-sea fish experiencing rapid ascent?
A)Increased gas solubility in blood
B)Accelerated pneumatic duct inflation
C)Reduced gas gland oxygen secretion
D)Expansion of swim bladder volume✓
💡 Explanation
During rapid ascent, a reduction in hydrostatic pressure causes Boyle's Law to operate, increasing swim bladder volume because gas expands, causing over-buoyancy. Therefore expansion of bladder volume occurs, rather than alternatives, which would decrease buoyancy, counteract initial expansion, or require different physiological triggers.
