← Nature & AnimalsWhich outcome occurs when a saltwater fish experiences gill damage effecting ionocyte regulation?
A)Dehydration and increasing internal sodium✓
B)Excessive water intake and urination
C)Reduced salt excretion via kidneys
D)Decreased water absorption in intestines
💡 Explanation
Gill damage impairs active transport via ionocytes, therefore osmoregulation fails, causing osmotic imbalance and dehydration along with increased internal sodium, rather than increased water intake via osmosis under normal conditions.
