Read the given statements and select the correct options: Statemetn-I: The ascending limb of loop of Henle is impermeable to water. Statemetn-II: Hence the filtrate becomes hypertonic.

Read the following statements and find out the INCORRECT statement . (a) During urine formation, the tubular cells secrete substance like H^+, Na^+ and HCO_3^- into the filtrate. (b) As glomerular filtrate move down in descending limb of Henle it gets concentrated and as concentrated filtrate pass upward in ascending limb of HL it gets diluted. (c) Conditional reabsorption of Na^+ and water takes place in PCT. (d) Reabsorption in ascending limb of HL is minimum.

Read the following statements about the excretory system in humans: I. A fall in GFR can activate the JG cells to release renin. II. ADH can also affect the kidney function by its constrictory effects on blood vessels. III.
