    Using dialysis tubing to model diffusion of a cell membrane and investigating the influence of solute concentration on osmosis Purpose * Discover how dialysis tubing diffuses the cell membrane * Explore the effect of solute concentration on osmosis Background A cell membrane is a very significant function in the human body. In one sense‚ it is used as a barrier to keep the enzymes‚ DNA‚ and metabolic pathways that bundles everything together. Cell membranes are also used as a gateway

    the body however if both fail to work it is a major issue and it causes problems as the kidney cannot filter the blood. How does a renal dialysis work: A dialysis machine tries to mimic some of the functions of a normal human kidney. One of the jobs of a kidney is to remove urea and some salts from the blood so they can leave the body in the urine. In a dialysis machine‚ blood from the patient runs through tubes made of a semi-porous membrane. Outside the tubes is a sterile solution made up of water

    Analysis During the experiment‚ a dialysis bag was used to mimic a cell membrane. Two ways why this model realistically represents a cell is because the dialysis bag is semi-permeable‚ like a cell. The bag was able to allow water in‚ as the size of the water molecule was small enough to be able to fit through the pores of the bag. Sucrose was not able to pass through as the molecules were too big to enter. This is similar to a cell because the size of a molecule can determine whether or not the substance

    Dialysis of starch‚ glucose and sucrose Introduction: Research question: Does the dialysis tube only allow certain substances to pass through the pores because of their size? Dependent and Independent variables: Independent variables: The temperature of the classroom The size of the molecules The size of the pores in the tube The concentration of the indicators Dependent variables: The substance will either pass the pores of the tube or not The result will vary in darkness (color) Controlled

    4 Starch Light blue‚ really clear Possible little protein with clear peptide or no protein at all Our results are correct because water and starch should not contain protein (starch is a polysaccharide but not of an amino acid) and therefore remained blue unlike Albumin and Pepsin which do contain proteins causing them to turn into a different color. Test tube # 1 is the controlled sample; a controlled sample is an experiment under regular conditions. Experiment Procedure include controlled

    cell and between cytoplasm and the external environment. The cytoplasm and extracellular environment of the cell are aqueous solutions. They are composed of water‚ which is the solvent‚ or dissolving agent‚ and numerous organic and inorganic molecules‚ which are the solutes‚ or dissolved substances. Organelle membranes and the plasma membrane are selectively permeable‚ allowing water to freely pass through but regulating the movement of solutes. The cell actively moves some dissolved substances

    Hemodialysis   Hemodialysis is a form of dialysis where the blood in the body is continuously removed and passed through an artificial kidney which cleans it. The treatment is an intermittent treatment and is performed ranging from three hours thrice weekly to eight or nine hours six to seven times a week.  The dialysis procedure is time consuming and a routine for CKD patients every week. The patient has to report to a dialysis center and if not lucky has to wait till his turn comes

    because the cup holding the dialysis tubing with the protein solution’s mass decreased by 7.61 grams and the volume decreased by 17.3 milliliters while the mass of the cup with the tubing holding glucose solution also decreased by 1.19 grams and the volume decreased by 2.2 milliliters (Emma Ricks and Allen Hansen). The movement of water into the protein solution bag caused the mass to increase by 7.95 grams and the volume to increase by 2.4 milliliters and the glucose solution bag increased by 1.97 grams

    stereotyping‚ racists’. I also see people of all colors getting jobs everywhere and work places being very diverse‚ so affirmative action has accomplished what it set out to do.
