the effect of the organic solvents on the cell membrane of the beetroot Objective: To investigate the effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to leak out by

temperature on beetroot This experiment is designed to investigate the effect of varying temperature (centigrade) on beetroot and its cells. My earlier experiment suggest that as temperature increases the integrity of the beetroot cell membrane will be destroyed and a subsequent release of beetroot pigment will be released into its surrounding milieu(in this case distilled water). In the experiment I will examine if my hypothesis (above) is correct. In order to conduct this experiment I would choose

Concentration (cont.) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases‚ the solution will become less clear‚ plus mass increases. The increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than the water potential inside the beetroot cell. I predict that

ORGANIC MATTER AND INORGANIC MATTE Organic matter is that which is living or has been alive‚ e.g. wood or coal. Inorganic matter is that which is not living and never has been alive‚ e.g. water or iron. Inorganic substances can be built up into organic compounds by living organisms. All living matter is made up of small units called cells. Some organisms‚ such as bacteria‚ consist of one single cell; others‚ like human beings‚ consist of many hundreds of millions of cells‚ all functioning together

Temperature is what I will be changing in the experiment. I want to find out what effect temperature has on the permeability of a cell membrane. Controlling other Variables- I will use measures to ensure that everything stays the same in my test to gain the best and most reliable results possible - Same volume of water that I put the beetroot into after heating. - The beetroot I use will be the same size each time‚ I will ensure this using a cork borer. - The beetroot will be heated for the same time for

Thriving Under Pressure ““I want to see how far I can go‚ I want to see what I can accomplish‚ I want to see what I can do‚ what I can be‚ what I can have. I want to see. I don’t want to see what I think I can do‚ I don’t want to see what I think is possible‚ I want to see what my life would look like if I didn’t count the cards‚ and if I was willing to go further than anyone else is willing to do if I had the mentality‚ so I woke up‚ and here I am.” The way athletes deal with pressure

Solution: This case talks about the disparity of the American political parties against the ownership of port operation by the state owned Dubai company. The republicans and Democrats being the opposition party were disfavoring the sale of some terminal port operation to DP World an Arab state company. Even though
