Which of the following is an incorrect match?

If Henle's loop were absent from mammalian nephron, which of the following is to be expected?

Read the given statements and select the correct option.
Statement 1: The final reabsorption of water from the urine into the blood occurs through the collecting duct of a mammaian nephron resulting in the production of hyperosmotic urine.
Statement 2: The loop of Henle creates a sodium gradient in the interstitial fluid.

Read the given statements and select the correct option.
Statement 1 : In the descending limb of loop of Henle, the urine is hypertonic, while in the ascending limb of loop of Henle, the urine becomes hypotonic.
Statement 2 : Descending limb is impermeable to Na⁺, while ascending limb is impermeable to H₂O.
