Detailed explanation-1: -Answer: Oxygen molecules move from air sacs in the lungs across cell membranes into blood. Robert sprays water on the veggies in the produce section to “plump them up". Water will diffuse (osmosis) and the fish will explode.
Detailed explanation-2: -When raisins are soaked in water, they swell. All this is due to the process of osmosis. The water molecules pass the cell membrane of the raisins and the raisins thus get swollen.
Detailed explanation-3: -You can consider osmosis to be a special case of diffusion in which diffusion occurs across a semipermeable membrane and only the water or other solvent moves. Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution.
Detailed explanation-4: -Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.
