Reverse osmosis is the removal of salts and sediments from water to make it drinkable to humans in large processing plants. Osmosis is one of four types of passive transport of water and materials through plants and plant cells. There are two types: active transport which requires the expenditure of chemical energy and passive transport. There are four types of passive transport: diffusion, facilitated diffusion, filtration, and osmosis. With this kind water usually moves from an area of low solute concentration to an area of high solute concentration. The plants cell walls are permeable to water molecules so the water can be absorbed by the cell.

Active transport requires the expenditure of energy; osmosis doesn't.

i know osmosis is specifically for water transport. Any other kind of transport, reverse transprt in ur case, involves all other materials.

sex drive is what makes you want to have sex. lust is when you want to have sex with someone in particular. Sex drive isn't a bad thing-it brings enjoyment and leads to replenishing the planet. The "biological drive" can be inactive until we are married. it is called self control and if you are a christian you should ask God to help you with this. by human standards maybe it is impossible but God makes the impossible possible.
