Water Concentration Lab Report

As stated in the introduction the hypothesis for this experiment was that the solution beginning with the higher concentration of KMnO4 and placed in water with the warmer temperature will diffuse through the artificial membrane quicker than the solutions beginning with the already diluted solutions and placed in water at a cooler temperature. This occurring because all of the solutions are trying to diffuse to where it is less concentrated because they are eager to diffuse down its concentration gradient. Therefore, since the one with the higher concentration has a larger gradient, it will try to diffuse quicker. The solutions with less concentration are already close to equilibrium, so they will not have to work as fast to reach it. The membrane will also be more fluid at the higher temperature, making it easier for the solution to move across it quickly. The results from each experiment supported my hypothesis. As seen in the graphs, both the solution with the 100mM of KMnO4 and the solution placed in the water at 48˚C diffused quicker than any of the other solutions. …show more content…
The large use of drugs is an example of this. Many drugs can imitate different things to trick the cell into letting it inside. Methamphetamine exemplifies this greatly by imitating dopamine. Dopamine transporters are responsible for removing dopamine from the synaptic cleft, but when Meth impersonates dopamine, it tricks the cell and is taken in by the dopamine transporters. Meth then enters the dopamine vesicles, forcing the dopamine out. The surplus of dopamine in the cell forces the transporters to start working in reverse, and through active transport, it pumps the dopamine out of the cell and into the synapse (University of Utah, 2006). According to the Utah Mouse Party stimulation, Meth is highly addictive because it works precisely on the brain’s reward pathway, making the user feel extreme pleasure and
