Within individual stacks are assortments of enzymes responsible for selectively modifying protein cargo. Note that a semipermeable membrane is not the same as a selectively permeable membrane. Osmosis is the movement of water molecules across a selectively permeable membrane. There are hundreds of various other techniques which have been used to selectively stain cells. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. The diffusion of water through a selectively permeable membrane is called osmosis. They are produced from an egg that the queen has selectively fertilized from stored sperm. Different codes are obtained by selectively delaying one of those bit streams. Some proteins are found to be responsible for selectively packaging cargos into COPII vesicles. His approach teaches people to treat evidence impartially, rather than selectively reinforcing negative outlooks. Thermal printers work by selectively heating regions of the special heat-sensitive paper. Researchers note that there a number of important benefits to expressing emotions selectively. This mutation was hypothesized to selectively abolish Gal expression. For this reason polypropylene is not often used in glazed selectively coated solar collectors.
