The scientific evidence which lead to the fluid mosaic model 19th Century: The earliest models were very simple‚ as they suggested that lipid soluble substances entered cells faster than water soluble substances; scientists in those days had also figured out that the layers of lipid were layers of fat. However‚ the downfall of the evidence provided was that scientists back in the day were not able to provide information‚ as to how a lipid layer could remain stable in contact with the water surrounding

Cost Volume Profit Analysis and Costing for the 21st Century Abstract Cost value is the analysis of different divisions or business units of a firm on the basis of their opportunity cost and economic rent (“Cost value definition”). The objective of cost value is to determine which division or unit should be kept‚ expanded‚ sold‚ or shut down (“Cost value definition”). Cost analysis is an important component of all economic evaluation techniques‚ especially when it comes to planning and self-assessment

The results shown on the graph show that there is a strong positive correlation between the average rate of conductivity and the surface area: volume ratio. As the surface area of the Agar cube increases‚ the rate of conductivity will steadily increase‚ too. The trend line of the graph shows as an exponential graph because at one point there will be no more conductivity due to too small or too big Agar cubes. A difference can be seen in the average rate of conductivity depending on surface area

It is composed of proteins‚ phospholipids and carbohydrates that are arranged in a fluid mosaic structure. Nucleus; the nucleus is the control centre of the whole cell. The nucleus of living cells contains genetic material that determines the structure and function of the cell it’s controlling. Nucleolus; the nucleolus is in the nucleus
