  • Which of the following statements is INCORRECT? I. Human kidneys can produce urine nearly six times more concentrated than the initial filtrate formed. II. An increase in body fluid volume can switch on the osmoreceptors and stimulate ADH. III. Substance like glucose, amino acids, Na^+ , etc., in the filtrate, are reabsorbed actively by the renal tubule whereas the nitrogenous wastes are absorbed by passive transport IV. Each kidney has nearly one million complex tubular structures called nephrons which are the functional units.
