Explanation: Osmosis is a process in which water move from an area of low solute concentration to an area of high solute concentration through a selectively permeable membrane. For osmosis to occur, it must be through a selectively permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
The Peppered Moth is widespread in Britain and Ireland and frequently found in ordinary back gardens, yet its amazing story has made it famous all over the world. It is one of the best known examples of evolution by natural selection,
i'm not sure if these are all the options you have but the answer is that active transport requires energy and that active transport is the movement of molecules from an area of their lower to their higher concentration against the concentration gradient
