Rahma took these notes on a process involving the movement of molecules, but she forgot to title them.–Causes molecules to move until they are evenly distributed–Moves from high concentration to low concentration–Has no need for added energy–Can occur with or without a membrane being presentWhich title best fits Rahma’s notes?

The notes describe molecules spreading from an area of high concentration to an area of low concentration until they are evenly distributed, without needing energy. This process is diffusion, which can happen with or without a membrane. Osmosis is specifically the movement of water across a selectively permeable membrane, so it does not fit all the notes.
