← Nature & AnimalsWhich homeostatic imbalance occurs if a freshwater fish's gill chloride cells fail?
A)Hyponatremia from diffusive salt loss✓
B)Hypernatremia from inhibited water influx
C)Hypokalemia from osmotic water gain
D)Hypercalcemia from disrupted kidney filtration
💡 Explanation
When chloride cells in a freshwater fish's gills fail, active transport of ions stops, because diffusion drives salt loss to the dilute environment, resulting in hyponatremia. Therefore, hyponatremia results instead of hypernatremia, hypokalemia, or hypercalcemia, which require different ionic imbalances or organ dysfunctions.
