which of the following statements are correct . ? (i) Fishes respire with the lungs . (ii) A water breather expends much nore energy in ventilating its respiratory surface than an air- breathing one. (iii) Lungs become empty after forceful expiration. (iv) A rise in Po_(2) increase the affinity of haemoglobin for oxygen. (v ) Lactic acid is produced in anaerobic respriation . (vi) Exchange of gases in the lungs is interrupted during expiration. (vii) A molecule of haemoglobin can carry 1-4 molecules of oxygen. (viii) maximum contraction of diaphragm causes maximum expiration. (ix) Respiratory movements are controlled by CO_(2) concentration of arterial . blood. (x ) Tidal volume is equal ot the vital capacity of the lungs.
