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 the same time. However‚ more water leaves a dilute solution (high water concentration) and passes into

with various sucrose concentrations and were placed into beakers of different sucrose solutions. Overall the results showed that the higher percentage of concentration gradient of sucrose‚ the more the artificial cells absorbed. Introduction: The phenomenon being investigated in the lab was how the concentration gradient affects the rate of osmosis in a cell. Osmosis is the passive movement of water from and area of high concentration‚ temperature‚ and pressure. The concentration gradient is the difference

Cockroaches and Hemolymph Concentration in the Body Abstract This lab was conducted to determine the concentration of hemolymph in the body of a cockroach. It was done by making serial dilutions to make a standard graph by injecting a dye into a cockroach and determining the concentration at different times with the use of a spectrophotometer to find the optical density which is measured in absorbance. Results showed that the concentration was not within the pre-experiment research range

worst places to be in were prisons called Concentration Camps. These prisons were very brutal‚ well organized‚ and there were different types of camps. First‚ these Concentration Camps were very brutal. Some examples of brutality are “when a person is captured they were beaten‚ tortured‚ starved‚ murdered by being worked to death‚ and by being put in gas chambers or large furnaces. A result of these actions 100 people died daily at the camps” (The Concentration Camps). The point of these “camps” was
