Which outcome occurs when marine fish actively drink seawater for osmoregulation?

💡 Explanation

When marine fish drink seawater, sodium transport across the intestinal lining occurs because water follows passively down the osmotic gradient, causing a net influx of both salt and water, increasing sodium levels. Therefore, blood sodium concentration elevates, rather than chloride cells decreasing, higher water potential, or dilute urine, which imply freshwater fish strategies.
