DIFFUSION= The movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Atoms and small molecules can move across a cell membrane by diffusion. OSMOSIS= Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane. SELECTIVE PERMEABLE MEMBRANE=a membrane (as a cell membrane) that allows

Desizing Desizing is done in order to remove the size from the warp yarns of the woven fabrics.The sizing material present on the warp yarns can act as a resist towards dyes and chemicals in textile wet processing. It must‚ therefore‚ be removed before any subsequent wet processing of the fabric. Object: 1. To eliminate the water repellent nature of sized cloth. 2. To increase the absorbency. 3. To reduce the consumption

most common of these utilize complexes of Fe and Mg‚ but other micronutrient metals including Cu‚ Mn‚ Mo‚ Ni‚ Se‚ and Zn are also important. Hemoglobin Hemoglobin is one of a group of heme proteins that includes myoglobin‚ cytochrome-c‚ and catalase. Hemoglobin performs the essential task of transporting dioxygen molecules from the lungs to the tissues in which it is used to oxidize glucose‚ this oxidation serving as the source of energy required for cellular metabolic processes.

Pseudomonas aeruginosa Pseudomonas aeruginosa is the bacteria of my initial unknown project. Determining which bacteria I had was completed by many steps. The one fact that I had‚ was that it was a gram negative bacteria because on the gram stain it appeared pink. Its cell wall is composed of a plasma membrane‚ periplasmic space‚ peptidoglycan and an outer membrane (lipopolysaccharide and protein). By looking at the agar plate it was easy to tell that it was not a swarmer and it did not have any
