Permeable to ions, Impermeable to water
|
|
|
Permeable to both ions and water

Explanation:
Detailed explanation-1: -1) Ascending limb of loop of Henle is impermeable to electrolytes, but is permeable to water. 2) Descending limb of loop of Henle is permeable to water but is impermeable to electrolytes.
Detailed explanation-2: -The descending limb is permeable to water but completely impermeable to salt, and thus only indirectly contributes to the concentration of the interstitium.
Detailed explanation-3: -Reason: The descending limb of loop of Henle is impermeable to both water and electrolytes.
