1.	Assertion : Most fish when out of water, die of suffocation. Reason : Atmospheric air contains far less oxygen content than the dissolved oxygen in water.
Answer» Correct Answer - c Although atmospheric air constains air contains far more oxygen content than the water (air contain 21 % oxygen and water contains 0.5-0.9% oxygen by volume depending on the termperature) , still most fish when out of water die of suffocation due to lack of oxygen . when fish is taken out of water the gills stick together thereby reducing the surface area. Reduced surface aea lower gas exhange so death ensues.
