    NAME: Donna Ha TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs INTRODUCTION: In order to fully understand the concept of this experiment‚ one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The

    Diffusion and Osmosis Diffusion -the process by which molecules spread from areas of high concentratiion‚ to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM DIFFUSION Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient‚ toward areas of lesser concentration. Think of food coloring that spreads out in a glass of water‚ or air freshener sprayed in a room

    zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a.

    Characters- No Sugar Through the characters names all the aboriginal names are given Christian names while the white characters almost without exception are given titles and surnames. This humanizes the aboriginal characters and dehumanizes the white characters while highlighting their position of power. White characters are demonized by their actions as well as their names‚ they refer to going back to the Tasmanian solution (pg44)‚ showing that they have no regard for the aboriginal’s lives

    Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

    the purposes of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more water inside the cell that outside which will cause water to diffuse out in attempt to reach equilibrium. Hypertonic solutions are when there is more water outside

    isotonic solutions and how they relate to osmosis. Osmosis is the process where a fluid passes through a semipermeable membrane‚ which moves from an area which the solute is present in high concentrations. As a result of osmosis‚ there will be an equal amount of fluid on either side of the barrier‚ creating an isotonic solution. When cells are placed in an isotonic solution‚ the movement of water outside of the cell is exactly balanced by movement of water in the cell. With a hypotonic solution‚ if
