    Introduction: The purpose of this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy.  This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement.  Diffusion is the passive movement of molecules

    Osmosis and diffusion are sometimes mixed up without much thought‚ but they are very different in many ways. Osmosis is a defined as the movement of water through a semipermeable membrane (). The membrane is fully permeable for the small water molecules‚ but is selectively permeable to any substance that is lager that a normal water molecule. One example might be a glucose and water mixture‚ when the solute is put into one side of a U-shaped tube that has a semipermeable membrane between the solvent

    Egg Osmosis Lab The purpose of this lab was to demonstrate an example of a spontaneous reaction and its connection to metabolism; in this case it was osmosis. The procedures that we used to complete the experiment were taking five eggs that had been soaked in a sucrose solution and then placing each one in containers of sucrose that each had different levels of concentration. The mass of each egg was measured before being placed into the solutions and then every 10 minutes after until they had soaked

    remained in power by taking away the Irish people’s land and reallocating it to Scottish farmers. The United Kingdom of Great Britain and Ireland was formed in 1801. The Irish people were upset by this and did not want to lose their independence. The Potato Famine that lasted from 1845 to 1848 took its toll on the population of Ireland‚ which went from 9 million to 3 million. The famine oppressed the undernourished people‚ yet Britain failed to offer sufficient support. Gladstone became the Prime Minister

    Introduction This experiment was osmosis and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs‚ and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs‚ then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs‚ again the
