16 The diagram below shows an experiment to investigate a certain physiological process String - Beaker Half filled visking tubing With Concentrated Salt Solution Distilled water a) Account for the observation made at the end of the experiment (4mks) ​

Answer 1

In tube 3, water molecules are moving towards higher concentration i.e., from beaker to tube content, thus the mass increases but in case of tube 4, water is moving out from tube contents to beaker, as the beaker contains more concentrated solution. Thus, the correct answer is 'Water is moving into Tube 3, and water is moving out of Tube 4.'
