Producing very dilute urine. d. Drinking a lot of sea water and getting rid of the excess ions. A chloride shift at the site of the tissues a Moves one chloride (Cl^-) into the cell, and one bicarbonate (HCO_3^-) out of the cell. b Moves one chloride (Cl^-) out of the cell, and one bicarbonate (HCO_3^-) into the cell. c Moves one chloride (Cl^-) out of the cell, and one carbonic acid (H_2 CO_3) into the cell. d. Moves one chloride (Cl^-) into .he cell, and one carbonic acid (H_2 CO_3) out of the cell. e. None of the above.

Explanation / Answer

29) Sea water is hypertonic to the fish living in it. The concentration of salt is higher in the sea water than inside the fish. The internal osmotic concentration is lower than that of the sea water. Due to osmosis, fishes lose water and gain salt. To compensate this process, fish living in the ocean drinks lot of sea water and gains salt. So, the answer for this question is option (a) hypotonic.
