Oxygen moving into an animal cell

Detailed explanation-1: -Swelling up of a raisin on keeping in water is known as Osmosis.
Detailed explanation-2: -Endosmosis: Osmosis is the diffusion of water across a selectively permeable membrane from a region of high water concentration to a region of low water concentration. Swelling of resins in water is called endosmosis.
Detailed explanation-3: -Aquatic respiration is the process whereby an aquatic animal obtains oxygen from water. This is done using diffusion of oxygen. Fish use the process known as countercurrent flow in which water and blood flow in opposite directions across the gills, maximizing the diffusion of oxygen.
Detailed explanation-4: -Shrinking of grapes in sugar syrup is because of osmosis as in this process the liquid moves from a region of higher concentration to a region of lower concentration. The sugar syrup has high solute concentration so the solvent moves from grapes to the outside.
