← Nature & AnimalsWhich outcome results when rapid ascent bursts lungfish's swim bladder?
A)Decreased buoyancy and internal oxygen✓
B)Increased oxygen and neutral buoyancy
C)Buoyancy loss without affecting respiration
D)Enhanced lung respiration adaptation outcome
💡 Explanation
Lungfish use a modified swim bladder for supplementary respiration; rapid ascent leads to bursting due to Boyle's Law. Gas exchange surface is damaged via diffusion, because of overexpansion, therefore oxygen delivery decreases rather than remaining constant, thereby causing both buoyancy issues and lower oxygen.
