Permeable Membrane Semi Permeable
856 wordsStudying the Effect of Various Glucose Concentrations on Osmosis in a Potato Osmosis is the process in which water particles move from an area of high water concentration to an area of low water concentration through a semi-permeable membrane until the concentrations are equal. Osmosis has the same basic theory as diffusion. Particles are moving from an area where they are in great concentration to an area where they are in low concentration until the concentrations are the same. Osmosis is this...

Permeable Membrane Semi Permeable
1,935 wordsI chose to experiment with the effects of salinity changes on the polychaete, Nereis succinct. Along with the other members of the group, Patty and Jeremy, I was curious to see whether the worms would engage in adaptive behavior when placed in a tank of water of foreign salinity, or whether they would simply continue changing osmotically until they reached equilibrium with the environment. The first step in our experiment was to simply observe the worms and get a "feel" for the ways in which the...

Permeable Membrane Semi Permeable
781 wordsOsmosis is the flow of water through a semi permeable membrane that blocks the transport of salts or other solutes through it. It is also defined as the net movement of water from an area of high concentration to a region of low concentration. Osmosis is a fundamental effect in all biological systems. When two water volumes are separated by a semi permeable membrane water will flow from the side of low solute concentration to the side of high solute concentration. If external pressure is applied...

Fatty Acids Petri Dish
4,956 wordsPlan The initial variable to be considered will be the effect that caffeine and temperature has on the heart beat and if it has a direct or indirect effect on the daphnia's lifespan. If there is enough time to consider a second variable however, the effects of a temperature or alcohol on the daphnia's body system will also be considered alongside the initial variable of caffeine. These will then be slotted into the same graph which will show us how the figure correspond to the results. In order ...

Permeable Membrane Semi Permeable
274 wordsOsmosis, in botany and chemistry, the flow of one constituent of a solution through a membrane while the other constituents are blocked and unable to pass through the membrane. Experimentation is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow. In a classic demonstration of osmosis, a vertical tube containing a ...
