___ 23.Which event does notoccur in the proximaltubule section of the kidney nephron?___ 24.Which of these statements about the proximaltubule is false?___ 25.Which event does notoccur in the ascendingportion of the loop of Henle?.___ 26.Which statement regarding the countercurrent multiplier systemis false?a. The descending limb of the loop of Henle is seemingly permeable to salt and other dissolved solutes, forming a hypertonicfiltrate.b. Interaction between ascending and descending tubular flow in the loop of Henle is an excellent example of negative feedback.c. Salt becomes recirculated and trapped in the medullary interstitial tissue fluid, increasing in “saltiness” as it accumulates toward the lower tip of the pyramids.d. Water is removed from the medulla by the higher colloid osmotic pressure of the blood in the vasa recta capillaries.e. Urea is recycled by passively diffusing out of the collecting duct specific urea transporters, through the medullary tissue, and into the ascending limb.
