← Nature & AnimalsWhich process enables marine bony fish to maintain osmotic balance in seawater?
A)Active transport of salt across gills✓
B)Increased urine production in kidneys
C)Decreased water absorption in intestines
D)Prevention of salt uptake via scales
💡 Explanation
In saltwater, bony fish use active transport,specifically chloride cells in the gills, to excrete excess salt accumulated through osmosis because they live in a hypertonic environment. Therefore active transport across gills enables osmotic balance, rather than increased urine, decreased absorption which have opposing and scales is protective
