Which outcome occurs when marine cartilaginous fish experience dehydration?

💡 Explanation

Elevated blood urea occurs because osmoregulation relies on urea retention to maintain isotonicity with seawater; therefore, dehydration concentrates urea, rather than producing dilute urine, because they actively uptake water and control salt excretion.
