    through electrodialysis and reverse osmosis. This procedure has worked for about 130 nations in North Africa and the Middle East. With this system‚ these nations are currently producing six billion gallons of usable water a day (Arrandale‚ 2002). Also‚ the United States has a total of about 1‚200 desalinating plants‚ most of which are in modest-sized communities. Recently‚ however‚ the desalinization process has become much more practical for metropolitan areas and reverse-osmosis systems have made significant

    Osmosis and Scientific Method Lab Report Abstract The purpose of the lab is to see how different size potatoes have faster water movement depending on the concentration of sucrose it was placed in. We had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the

    One purpose of the experiment was to gain an understanding of diffusion and osmosis‚ specifically in context of a plant or animal cell reaction to an isotonic‚ hypotonic‚ or hypertonic solution. Another objective was to understand the nuances of simple diffusion‚ facilitated diffusion‚ and active transport and to explicate the characteristics affecting the rates of diffusion. The next objective was to be able to explicate the partition coefficient and its influence on hemolysis. The final objective

    Biology Essay Amanda Liao 09/05/13 Clean Water In today’s world‚ one of the most basic problems facing our society is the absence of clean water that we use and drink in daily life. The importance of clean water is self-explanatory. In spite of the fact that 70% of the earth’s surface is covered by water‚ there is only 2.53%of fresh water that we can actually use. For the only 2.53% of fresh water‚ some is not safe and clean to use and it is harmful to human body. Polluted water is a big risk to

    partially supported because glucose left the bag and is proven by the positive test on the surrounding water. Also the beaker turned orange because of osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable

    Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy.  This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though).  Diffusion or osmosis occurs until dynamic equilibrium has been reached.  This is the point where the concentrations in both areas are equal and no
