For example‚ in the American Revolution‚ we won‚ but is it really victory when 8‚000 Americans

Biological Membranes: A simulation Introduction Diffusion is the process by which collisions between molecules cause to spread apart. This movement is described as movement from an area of greater concentration to an area of lower concentration. Hence‚ diffusion continues until the molecules are equally distributed. This is to ensure that molecules have reached a state of equilibrium. Diffusion occurs spontaneously‚ no energy is involved. In cells‚ Diffusion occurs through cell membrane which is selectively

the permeability of cell membranes Introduction For my coursework‚ I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane‚ also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm. The membrane is called a bilayer as it has a double layer of phospholipids. Within the cell membrane there are many biological

The effect of temperature on the cell membranes of beetroot cells and amount of pigment released. Apparatus • Corer size 4 • White tile • A Beetroot • Automatic Water Bath • Segregated knife • A thermometer • Stopwatch Method: • First take the white tile and the corer. Then collect a cylinder of beetroot by pushing the corer into the beetroot and withdrawing it. The cylinder remains inside the corer- so push it out with the end of a pencil. • Collect 3 cylinders

Name: Marion Paxton Diffusion Lab Introduction: In this lab you will observe the diffusion of a substance across a semi permeable membrane. Iodine is a known indicator for starch. An indicator is a substance that chances color in the presence of the substance it indicates. Watch as your teacher demonstrates how iodine changes in the presence of starch. **Prelab Observations: Describe what happened when iodine came into contact with starch. The cornstarch turned blue-black Procedure:
