Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in which the

The Australian Sugar Cane Industry The Australian sugar cane industry is one of the largest industries in Australia and continues to grow today. It is the third largest raw sugar supplier after Brazil and India despite sugar being produced in over one hundred countries. It is also the seventh largest agricultural exporter in Australia. It is the second largest export crop after wheat and the fourth major export earning agricultural product. Its value of production is worth 1.5-2.5 billion dollars

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

I snorted the sugar just short of the keyboard‚ onto the mouse pad‚ and all down my front.
