    and products does not change with time. Before this experiment‚ we were educated on how osmosis functions. Osmosis is a process which molecules and water take to usually get through a selectively permeable membrane in order to reach equilibrium. It is a passive transport which requires no ATF and water moves from high to low water concentration. When osmosis is completed‚ there should be an equal concentration o water on both sides of the experiment. We have also learned about the iso osmolar point

    in several years‚ they have become a huge part of our lives‚ our indispensables. J.J. Thomson was inspired by some scientists and he provided us the opportunity of having televisions in our lives. Also other scientists improved his thoughts and experiments which leaded to the invention of the television afterwards. It is not that simple of course. Let’s look at the backstage... By the beginning of the 20th century‚ there were some problems that had not been solved. The main problem was; not being

    GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict

    Carbon nanotube 1 Carbon nanotube Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with [1] length-to-diameter ratio of up to 132‚000‚000:1‚ significantly larger than for any other material. These cylindrical carbon molecules have unusual properties‚ which are valuable for nanotechnology‚ electronics‚ optics and other fields of materials science and technology. In particular‚ owing to their extraordinary thermal conductivity

    “Test-Tube Burgers” One summer when taking a trip to a friends country house for a weekend I took on the challenge of being a vegetarian. My friend‚ an only child‚ had been raised a vegetarian by parents who were also vegetarians; never once in his life had he eaten meat. Although the family was tolerant of whatever I did‚ I decided this was an opportunity to try it for myself and see what it would be. At the end of the few days I found it quite easy‚ although in reality I did not consume nearly

    Demonstrating osmosis Introduction The movement of water in and out of a system bounded by a membrane permeable to water‚ but not certain other substances‚ can be inferred by either mass changes or volume changes in that system. It is possible to monitor other changes in physical conditions‚ such as texture. Monitoring mass enables quantification of the changes‚ whereas other changes may only be qualitatively measured.

    measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis‚ I hypothesise that as the solution of the starch in each tube increases‚ the water

    Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around
