transport of materials in three semi-permeable membranes: dialysis tubing‚ eggs‚ and onion cells. Background Information 1. Diffusion is the movement of solutes from high to low concentration. Osmosis is the movement of water from low to high concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is when the concentration in

membrane OBJECTIVES: To investigate the effect of concentration of blackcurrant squash on osmosis in chipped potatoes. INTRODUCTION: In biology‚ osmosis is defined as the diffusion of solvent molecules (usually water molecules) across a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration. Osmosis is of great importance in biological processes where the solvent is water. The transport

Project Stat. Math 5389 Graph Analysis# 1Spring ‚ 2012Noemi Bores | Identifying Misleading Graphs Graphs are pictorial representations of numbers. Therefore‚ at the least‚ we should expect that the representation of the numbers be proportional to the numbers themselves. Unfortunately‚ this is not always the case. In some cases this occurs because the graph designer wants to give the impression of better performance than is actually the case. In other cases‚ the designer might not have any

Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

When dealing with machine generated data‚ we often tend to see the data to have better understanding of a structural form. Many such data can be represented in the form of graphs. By laying out a graph‚ we can untangle information and intuitively show relations of objects. Automated graph drawing remains a difficult placement and layout problem. This problem
