Removal of proximal convoluted tubule from the nephron will result in:

1. More concentrated urine
2. No change in quality and quantity of urine
3. No urine formation
4. More diluted urine

Correct answer: More diluted urine

Solution

The proximal convoluted tubule reabsorbs a large fraction of filtered water and solutes. Removing it leaves more water in the tubular fluid, so the final urine becomes less concentrated and more diluted.
