Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

Rimando Geography 2 September 19 2012 Cultural Diffusion: Sushi Sushi is one example of cultural diffusion in which went on to expand on a global scale from a native treat of Japan into an international delicacy. To scope out on how sushi became an international sensation‚ there are 4 factors that identify the chronicles of its origins and through an expansion of this treat internationally. These 4 factors are: the hearth (originating from) ‚ evolution (how

Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable

primary alcohols used were; methanol and ethanol‚ and the secondary alcohol was; isopropyl. Of this the secondary alcohol‚ isopropyl was discovered to be the most effect alcohol to make DNA precipitate‚ as it produced the most amount of DNA. This investigation of extracting DNA is significant due to the study taken providing understanding and knowledge on DNA; this allows people to find out information of the cell structure‚
