variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over three times greater than the 20 MWCO.

they both have significant differences in their portrayals of society during the time of the album‚ 1991. The "death" tracks are a reflection of how Ice Cube views his life and his society in South Central Los Angeles when the album was created. He paints a very grim picture. There are eight main tracks that have to do with "death" and they all cover a different aspect of struggles in the inner city. Cube covers the angst expressed towards

The film ’The Cube’ directed by Vincenzo Natali‚ explores many of the key and fundamental concepts of Society and Culture. These concepts include society & culture‚ environment & time and power & authority. The characters in the film (Leaven‚ Quentin‚ Worth‚ Holloway and Kazan) experience each of these concepts and they each play a role in the outcome of the film. The concepts of society and cuture both play a major role in the characters interactions and therefore in the films outcome. When the

can we increase the rate at which sugar cube be dissolve in water? Hypothesis: My hypothesis is that the hot water will dissolve the most sugar among most of our other methods. I picked the hot water because hot water molecules tend to move very fast. which increases the speed of how the molecules take away the sugar molecules which make sugar dissolve quicker inside of the hot water. Materials: 3 cups Water and hot water Spoon Sugar cubes Stop watch Mortar and pestle Graduated

A four modes approach to ration health care Typically‚ modern health care systems are faced with the presence of conflicting policy goals‚ like managing the increasing health care costs and providing equal access to the health care that is needed (Cutler 2002). Therefore‚ the Dutch health care system moved over time from an etatist policy program to a market-oriented program. A process called rationing of health care is often applied to maintain health care costs. To date‚ health insurance is

observed the effect in pollen floating in water‚ where it is visible with the naked eye. Through experimentation‚ Brown determined that the specks of pollen were not propelling themselves independently‚ but rather that their motion was pseudo-random. Jean Perrin‚ a French physicist who later won the Nobel prize‚ spring boarded off of Einstein’s work. Using Brownian motion as evidence‚ he proved in 1911‚ once and for all‚ that matter is made of atoms and molecules. Diffusion Diffusion‚ also called

Where as the active transport requires energy from the molecule to be moved. oFacilitated diffusion can only move in one direction from high concentration to low concentration‚ which is with the gradient. Where the active transport can move from both low concentrations to high concentrations‚ therefore it can move against the gradient where as the facilitated diffusion can not. The process of active transportation is when a molecule work together with the active side of a protein

Hands On Approach to Diffusion and Osmosis Abstract A. Plant and Animal Cell Diffusion and Osmosis In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a completely random fashion‚ and the smaller particles moved with more speed than the larger particles. B.
