It was observed that an experimental subject consistently passed a larger volume of urine after consuming three cups of black unsweetened tea containing caffeine than after consuming an equal volume of sweetened lemonade. Assume all other variables were carefully controlled. Select one: a. The sugar in the lemonade provided additional energy for the active transport of water out of the nephrons. Select one: b. The caffeine in the tea caused a reduction in the secretion of ADH by the pituitary gland. c. The caffeine in the tea caused the liver to produce more urea. d. The sugar in the lemonade blocked the reabsorption of water by the distal tubules of the kidney.
