Introduction In this experiment I aim to find out if caffeine has an effect on the heart rate of daphnia. Daphnia are water fleas that have a sort of heart that we can see in magnification. We can count the number of heart beats in a minute of a regular daphnia and try and get a new one with the same specifications as the old one that may have died. It is also a good idea to get a new one as we want to see how much it affects it from ordinary instead of adding the caffeine one after another

level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate (CA 202 ) as the third membrane and PVDF (FP 100 ) that act as the fourth membrane. In order to identify the characteristic of all four membranes‚ experimental procedures should be done. The variable for this experiment is the membrane maximum inlet

Recommended Option In this report I am going to recommend a business alternative to Digital Ltd‚ based on a CVP analysis of the three business plans the company has provided. Before going to more detail of the recommended option‚ I would like to emphasis on the importance of CVP analysis. As CVP is a ‘systematic method of examining the relationship between changes in activity and changes in total revenue‚ expenses and net profit’ (Drury‚ 2000)‚ it is a very useful tool for managers to consider
