In the ascending limb of the nephron loop (loop of Henle),the:
A)thin segment is not permeable to sodium ions,chloride ions,or water.

The thick segment of the ascending limb of the nephron loop is impermeable to water but permeable to sodium and chloride ions. This allows for the reabsorption of these ions, which helps to create a concentration gradient for the reabsorption of water in the collecting ducts. The thin segment is permeable to these ions, but not to water. Movement of water and solutes is active, not passive.
