Solution:

When the urine moves through the descending limb, it becomes hypertonic and as it passes through the ascending limb of the loop of Henle, it becomes hypotonic because the descending limb is permeable to water and impermeable to sodium ions, while the ascending limb is impermeable to water and permeable to sodium ions.
