The effect of temperature on the permeability of cell membranes Introduction For my coursework‚ I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane‚ also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm. The membrane is called a bilayer as it has a double layer of phospholipids. Within the cell membrane

There is a great deal of evidence to support that evolution did indeed happen. Evolution is the changes in a population over time‚ it’s explained through descent with modification and natural selection. The findings from earlier thinkers all back this evidence up. Charles Darwin used evidence he found from research and studying the work of other scientists who studied fossils to support his claim that modern organisms are the descendants of ancestral species that were different from those of today

Food prices in South Africa have increased by over 10% within the last year. This has a negative effect on the people with a lower income and who need to spend more of their total income on food. The cost of the standard South African food basket‚ which is expressed as a share of the average monthly income for the poorest 30% of the population has increased from 32.4% in October of 2010 to 36.4% in October 2011. Some of the determinants of the increased food prices occurred due to higher administered

17th‚ October 2010 Margarita SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the
