Abstract The experiment was carried out to investigate at which point the potato has reached its isotonic environment. From the results‚ when the concentration increase to 0.3M‚ the mass of the potato slices decreased by -3.26%. We can conclude we see that as we increased the sucrose concentration it was a decrease in the percent change. Introduction All cells have membranes that are selectively permeable. In other words‚ they allow certain things in and certain substances are not allowed to

area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are very tiny and can only be seen with a microscope‚ so you are going to use sticks of potato tissue in solutions that have different concentrations of dissolved substances to observe the effects of osmosis on living tissue. There are three basic relative concentrations of solutions. An isotonic solution has a concentration of dissolved particles

From 1882‚ Van Gogh painted around ten works with nine of them being lithography while one being etching. Further to that‚ the painting of Potato Eaters was formerly intended for the marketplace‚ but later‚ Van Gogh created a lithograph of the same painting so that it may reach a larger audience (Li et al. 1177). In the same manner‚ Van Gogh was able to bring transformations in his styles as

The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay was performed. Using forceps a small paper disk was dipped into the second beaker containing the potato catalase for exactly 5 seconds. It was next dried on a paper towel for 5 seconds‚ and finally placed at the
