This is lowering the percentage of transmission as more pigments are leaking out due to the denatured proteins and the lower the transmission (the darker the colour). The hydrophobic tails point into the centre of the membrane.

I decided not to use potato because, although it is cheap and readily available, it tends to break down very quickly, and this is shown in the dark colour it changes into.

Then using the profile graph (appendix) i managed to work out that the highest number of common limpets will be found between 3m and 6m at vertical height above chart datum. I was hoping if anyone would be able to give me any tips as to what to put in the evaluation. From 0c to 20c, theres a slight increase in the average percentage of transmission.

Use a calorimeter to measure the absorbance of each cuvette compared to the absorbance of just plain distilled water and this will give a distinct comparison to show different absorbencies using different temperatures. The hydrophilic heads point towards both inwards towards the cell cytoplasm and outwards towards the aqueous external environment.

This is because when water freezes, it expands and this makes the cell membrane bursts.

All living organisms are surrounded by membranes, so i had a wide choice of sources to choose from.

This is shown in the graph as gradual decrease in transmission. This is suggesting that membrane permeability increases with temperature and therefore more colour leaks out. Also, would anyone be able to tell me what the graph should look like if light absorbance is on the y axis? The graph should look like what your data shows.

    Hiya! Im also doing the beetroot coursework, and im on the evaluating, which has never been my strong point. This permeability will be detected due to a colour change from light to dark purple. Objective the objective of this experiment is to examine how a change in temperature will affect the permeability cell membranes. Repeat the experiment 3 times for each of the different temperatures to ensure that the results are reliable if the results are similar. This is lowering the percentage of transmission as more pigments are leaking out due to the denatured proteins and the lower the transmission (the darker the colour).

    After this takes place, the enzyme remains the same, and repeats this process. There are prizes worth 2,000 to be won in tsrs exclusive competition.

Repeat the experiment 3 times for each of the different temperatures to ensure that the results are reliable if the results are similar. This is because when water freezes, it expands and this makes the cell membrane bursts.

    The cell surface membrane is composed of many components one of which is phospholipids.

    The cell surface membrane is the boundary between the cytoplasm in the cell and the environment, so it has the important job of controlling the movement of substances in and out of the cell. A phospholipid is composed of 2 main parts, a hydrophobic head which is attracted to water and a hydrophobic tail which is repelled by water but mixes readily with fat. Then using the profile graph (appendix) i managed to work out that the highest number of common limpets will be found between 3m and 6m at vertical height above chart datum. The overall trend seems to be that as the temperature increases, the average percentage of transmission decreases.
