Candide Voltaire‚ a French philosophe and writer‚ wrote this document during the Enlightenment. He illustrates his opinion on many Enlightenment ideas‚ such as Leibnizian optimism‚ deism‚ and religious tolerance. He impacted many people‚ including Benjamin Franklin and Thomas Jefferson with his belief of religious toleration and civil rights. His view on organized religion also influenced the French Revolution. One of the Enlightenment views Voltaire addresses is Leibnizian optimism‚ or the

DIFFUSION AND OSMOSIS Chapter 3 of your textbook explains diffusion and osmosis. Diffusion is simply the net movement of atoms or molecules from a region of higher concentration to a region of lower concentration. The force behind the movement is heat or kinetic energy (also called Brownian motion). Diffusion occurs when you spill water on the carpet floor and it spreads out‚ or when you open a bottle of perfume and it leaves the bottle and spreads throughout the air in the room. Osmosis is a

Biology GCSE Coursework: Osmosis in Potato Chips Skill Area P: Planning Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Hypothesis: Osmosis is defined as the net movement of water or any other solution’s molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially

Osmosis Osmosis is just a special case of diffusion - where water diffuses through a membrane which has different concentrations on either side. Permeable means "allows anything to pass through". Membranes in cells allow small molecules (water) to pass through‚ but prevent bigger ones from passing. This is called "selectively permeable". Take a look at the following animation; If a selectively permeable membrane separates the two solutions‚ water moves through it in both directions at

Sylvester 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) ‚

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

the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through osmosis therefore there will be no percentage of weight change in potato cubes 2) The osmolarity of salt within the potato cubes lie between 0.8% and 1.0%. Thus saying‚ solutions of salt ranging from 0.0%(distilled water) to 0.8% will be hypotonic while the

Garfield wants the knowledge of the books to go to his brain. Basically‚ the high concentration (book knowledge) going to low concentration. (his brain) Diffusion is the process by which a substance moves‚ without energy‚ from an area of high concentration to an area of low concentration. It’s also the main method by which small molecules move across the cell membrane. Since molecules are always moving and bumping into each other‚ the more molecules are in an area‚ the more collisions there will
