Diffusion Introduction Diffusion is the net movement of ions or molecules from a region of high concentration to a region of low along the concentration gradient until equilibrium has been reached. The steeper the gradient the faster the rate of diffusion. There are a few types of diffusion. Three (3) of those are: Facilitated Diffusion- refers to diffusion of substances across a cell membrane with the help of transport protein. Dialysis- refers to the diffusion of solutes across a semipermeable

The Effect of Molecular Weight and Time on the Diffusion Rate of Potassium Permanganate‚ Potassium Dichromate‚ and Methylene Blue.1 Arantxa Alex Carpio Group 1 Sec. X – 4L March 24‚ 2015 ABSTRACT The effect of molecular weight and time on the rate of diffusion was determined using the agar-water gel test. A petri dish of agar-water gel with three wells was prepared and a prepared solution of each substance was dropped on each well; one with potassium permanganate (KMnO4)‚

Biology 107 Section 1 11/4/13 Diffusion & Osmosis Introduction The purpose in this experiment was to estimate the osmolarity of potato tuber and celery cells by change of weight.Pieces of potato tuber and celery would be incubated in different sucrose solutions to find out the molarity at which weight of potato and celery tissues do not change. My hypothesis was that the Table 1: Group Data for Experiment:Estimating Osmolarity by Change in Weight Table

Ronald Wilson Pd:4th 11/16/12 Introduction In this experiment diffusion and osmosis is the main idea. When using diffusion and osmosis you are trying to separate different solute concentrations on either side of the membrane. Only a solute’s relative concentration‚ or water potential‚ affects the rate of osmosis. The higher the concentration of solutes‚ the faster water will flow through the membrane to equalize the concentration. The way we describe the movement from higher to lower concentration

Japan expansion evolved by unification where Japan regained their islands. Tokugawa Shogunate unified Japan by consolidating with islands near Japan’s territory. With all of Japan’s territory being under his rule‚ japan expanded. A cultural continuities in Japan would be feudalism. Japan became decentralized‚ where all people in Japan was under the rule of Tokugawa shogun or their emperor at that time. The 46 Ronin were also a continuities. The 46 Ronin was a story about the importance of the

Cultural differences regarding Japan and Marijuana Japan’s history with relation to marijuana is different than in the United States. Prior to occupation by US forces‚ nearly 200‚000 farm households cultivated hemp (Fulford 2003). It was not until the US imposed anti-narcotic laws that Japan faced issues of legal/illegal debate. During WWII‚ Japanese Imperial Army soldiers were allowed to smoke marijuana to ease the stress of battle. The smoke of the marijuana plant also held spiritual values in

1.What were the triggers of cultural change in Japan during the 1990s? How is cultural change starting to affect traditional values in Japan? In the 1990s when Japanese economic growth slowed down for a long time firms where forced to change the way of doing business. They started to fire older employees. The younger generation‚ which grow up wealthy‚ saw this process and concluded that loyalty to one company might be not the best for themselves. The difference between the postwar generation and

Thailand: This is a country that has a lot of aspects that could be considered great as a supervisor‚ but other aspects that might make it challenging for them also. There is a large number of high power distance in this society‚ which is part of how this culture views as normal because they accept that if you’re at a below and not above position then you can’t expect to be listened too. What Power Distance explains is that a particular society is willing to accept a certain "inequality" in power
