1.	Question : Match the following columns.
Answer» `{:(A,B,C,D,E),(3,5,4,2,1):}` `{:(A,B,C,D,E),(3,4,1,5,2):}` `{:(A,B,C,D,E),(1,3,2,5,4):}` `{:(A,B,C,D,E),(3,1,4,5,2):}` Solution :Proximal convoluted tubule is involved in REABSORPTION of 70-`80%` of electrolytes. Distal convoluted tubuleis involved in secretion of hydrogen, potassium ions and `NH_(3)` in order to maintain pH and sodium - potassium balance in blood (ionic balance). Henle's loop (the descending limb) is permeable to water, but almost impermeable to electrolytes. This CONCENTRATES the urine (filtrate)as it moves down. Counter current mechanisms HELPS to maintaining a cocentration gradient in the medullary interstitium of kidney. Renal corpuscle involves filtration of blood VIA glomerulus adn Bowman's CAPSULE.
