Question

A drowned person cannot survive underwater even though the air is dissolved in water. Comment.​

Answer 1

Answer:

This is because humans breathe through lungs and not gills. Lungs are not adapted to be able to separate the oxygen that is in water. Fishes on the other hand have gills. fishes take in water through their mouth, push it against there gills and the oxygen is separated and utilised for breathing. Humans aren't adapted to do this.
