  • It happens because of diffusion
  • It happens because of osmosis
  • It happens because of gravitation force
  • It happens because of shaking hands
Osmosis is the passage of ...1... molecules from a region of their higher concentration to a region of their lower concentration through a ... 2 ... permeable membrane
  • 1: sugar, 2: completely
  • 1: sugar, 2: partially
  • 1: water, 2: completely
  • 1: water, 2: partially
The diagram shows two chambers with different concentration of molecules separated by a selectively permeable membrane. Predict what will happen to the water molecules ?

  • move from B to A due to diffusion
  • move from B to A due to osmosis
  • move from B to A due to active transport
  • move from A to B due to osmosis
Active transport is movement of particles through the cell membrane from a region of ...1... to a region of ...2... using energy in the form of ...3...
