    Marie Gorjon Mrs. B Anatomy & Physiology 168 March 14‚ 2014 Diffusion across a Selectively Permeable membrane Introduction: Diffusion is movement of molecules from one area of concentration to another. This process is vital for the life functions of cells. Cells have selectively permeable membranes that allow only certain solutions to pass through them. Osmosis is a special kind of diffusion that allows water to go through semi-permeable membranes of high water potential to a region of lower

    Demonstrating osmosis Introduction The movement of water in and out of a system bounded by a membrane permeable to water‚ but not certain other substances‚ can be inferred by either mass changes or volume changes in that system. It is possible to monitor other changes in physical conditions‚ such as texture. Monitoring mass enables quantification of the changes‚ whereas other changes may only be qualitatively measured.

    Summary The poem begins with our speaker at his desk‚ his pen poised to begin writing. He gets distracted by the sound of his father outside‚ working in the garden‚ and this sends our speaker into a spiral of memories about his father working in the potato fields when the speaker was a young boy. The memory stretches even further back to his grandfather and the hard work he did as a peat harvester (there’s all kinds of hard work going on). Eventually‚ our speaker snaps out of his daydream‚ and we find

    Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears
