WebJan 30, 2011 · How do water molecules move during osmosis? Water molecules move from the region of high concentration to region of low concentration. No ATP spent in such a process. WebJul 30, 2024 · A number of factors can affect the rate of diffusion, including temperature, molecular weight, concentration gradient, electrical charge, and distance. Water can also move by the same mechanism. This diffusion of water is called osmosis. In this lab you will explore the processes of diffusion and osmosis.
Weblist which molecules, in general, can freely diffuse across the plasma membrane of a cell; describe what drives osmosis (why do water molecules move?) explain why water moves out of a cell when the cell is placed in a hypertonic solution; explain why water moves into a cell when the cell is placed in a hypotonic solution WebMar 30, 2015 · This is because cornstarch and water molecules have fairly fixed positions. They cannot move freely under pressure and behave more like a solid. However, if there is no pressure, the mixture behaves like a liquid. Quicksand is also a thixotropic mixture, the more the pressure you apply the harder it gets to free yourself. The best way of ...
