    • 2 Pages

    Osmosis Lab Conclusion The purpose of this lab is to determine whether salt affects the movement of water in the cell. Independent variable is the factor that affects the value of variables dependent to it. In osmosis lab‚ the independent variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled

    Practical Work Nº2: “Different methods to control osmosis” Aim: observe and test the process of osmosis through different kinds of methods: the weigh (potato)‚ the density (beetroot) and under the light microscope (onion). Hypothesis: according to the encyclopedia definition osmosis is the diffusion of a liquid (most often assumed to be water‚ but it can be any liquid solvent) through a partially-permeable membrane from a region of high solvent potential to a region of low solvent potential. Thus

    Lab Report on Osmosis and Diffusion Biology 1‚ Period 3 March 15‚ 2010 Lab Team: Jason Perez‚ Kicia Long‚ Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing. Materials Used 2.5 cm dialysis tubing 15% glucose

    2.3. Membranes and modules for forward osmosis: 2.3.1. FO Membranes Generally‚ any dense‚ non-porous‚ selectively permeable material can be used as a membrane for FO. Such membranes have been tested (in flat sheet and capillary configurations) in the past for various applications of FO. In early studies‚ the researchers applied various FO membrane materials‚ including bladders of pigs‚ cattle‚ and fish; collodion (nitrocellulose); rubber; porcelain; and goldbeaters’ skin [36].

    Well how about a chicken? More and more Americans are in favor of the urban chicken however‚ less than one percent of urban households own chickens. It’s time to make a change. Every household in America should have free range backyard chickens because they provide great nutrition‚ they are a source of therapy and they are good for the environment. First‚ every household in America should have free range backyard chickens because they provide great nutrition. Free range eggs from your backyard

    Introduction: The purpose of experiment 1 was to demonstrate the principle of simple diffusion and understand how to make % solutions. Exercise 2 demonstrated the principle of osmosis: observing the movement of water by osmosis from an area of lower concentration of a solute to an area of higher concentration of a solute. Materials and Method: Refer to pages 47-51 of Bio 203L Lab Manual. Results/ Discussion: The effect of the chloride ion on its rate of diffusion in agar means it will diffuse

    Michelle Yeung Bio 101 Cyrus MacFoy June 16‚2015 Diffusion and Osmosis Exercise I. Molecules are always in constant movement. Molecular motion is a form of energy‚ the kinetic energy of molecules. The Brownian movement is the movement of small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration
