    an egalitarian society. Secondly‚ other countries have benefited their society by passing women’s suffrage. Lastly‚ women are just as hard-working as men and deserve as much as men do. To start off‚ I without a doubt believe that women should be able to vote as Australia or we would not be known as an egalitarian society. Egalitarian means to treat everyone equally regardless of their gender‚ social class‚ nationality‚ education‚ family‚ appearance or job. Why should we call ourselves an egalitarian

    After age 79‚ Texas law requires that drivers renew their licenses in person and take an eye test. At 85‚ drivers have to renew every two years. They do not have to take written or driving tests. Texas DPS regulations say drivers’ license office representatives "are trained to evaluate an applicant’s physical appearance and conduct a basic medical evaluation on every individual who applies for a drivers’ license." After he was renewed‚ the Pickles daughters parked their father’s car at one

    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

    Aim: To investigate how effect of Detergent 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

    1. The cell membrane structure is vital to the life of the cell. The cell membrane is shaped as having a phosphate head at the very outer surface‚ and two fatty acid tails hanging from it. The membrane is double‚ so at the tip of the fatty acid tails‚ there are two more fatty acid tails attached to another phosphate head. This is what it looks like: <br> <br>The reason the cell membrane is shaped like this is mainly to control the water flow in and out of the cell. Water is very important to

    Investigate factors affecting cell membrane permeability in beetroot. Research Question: How does variation in temperature affect the permeability of cell membranes? Background Information: In this investigation I will want to identify how variations in temperature effect the permeability through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC

    electrically excitable membrane changes its electric potential. In other words‚ how is the cell membrane excited? At the surface of the cell membrane‚ there are three classes of gated channels exist‚ chemically gated or ligand-gated channels‚ voltage-gated channels‚ and mechanically gated channels. Originally‚ at the resting membrane potential‚ most of the gated channels are closed. However‚ when these gated channels open‚ the movement of ions across the membrane will changes the membrane potential. In the

    Plan:- Independent Variable- 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
