For his 40th birthday, I had my eye on a vintage watch. It would complement his tattered sweaters and declare to the world that he is, in fact, employed. But when I mention this to him, he balks. He says that what he really wants isn't a good, but a service: a threesome with me and another woman.
Osmosis is a special type of diffusion whereby water is moved from an area of high water potential into an area of lower water potential. In principle, the same concepts applyâ¦ for osmosis as it does for diffusion. The particles travel in a concentration gradient without the use of energy.
Facilitated diffusion is another type of passive transport in which substances travel through the cell membrane. One substance that undergoes facilitated diffusion is glucose. Glucose, like water, relies on a special carrier protein. This protein is called a GluT transporter.
