If reabsorption in nephrons becomes very low, what may happen to urine volume?
Answer and explanation
Correct answer: Urine volume may increase
The governing concept is selective reabsorption during urine formation. Filtration first places water and small solutes in the nephron tubule, after which useful water and substances are normally returned to the blood. If reabsorption becomes very low, less water is recovered, so more filtrate remains and urine volume may increase. Therefore option A is correct; the other choices describe unrelated or biologically impossible effects.
