For this experiment I am investigating how the light intensity as my limiting factor will have in impact on the amount to oxygen produced‚ to should the rate of photosynthesis.Therefore‚ all the controlled variables must remain constant‚ if not there could be an affect on the accuracy of the dependent variable. The CO2 levels are the same for each trial because before placing the sodium hydrogen carbonate i will weigh it with a measuring scale for 1.5 grams. After completing the five measurements

Enzymes are catalytic proteins that selectively speed up chemical reactions without by consumed by the reaction itself (1). Enzyme activity is significantly affected by factors such as temperature‚ substrate concentration‚ enzyme concentration and pH. Enzymes are highly specific and only catalyse one specific chemical reaction‚ speeding up the reaction by lowering the activation energy‚ the energy required to start a chemical reaction (2). At high temperatures and with various mechanical forces or

My results and the graph indicate that as you add the caffeine to the daphnia‚ the eart rate of the daphnia increases for example the daphnia’s heartbeat is 120 without caffeine‚ however when caffeine is added it is increased to 168. My graph shows a positive correlation and the error bars are also very small which shows that the results have a small range which suggests that my results are accurate and reliable. I think that the experiment was conducted well however there may be some ethical issues

Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes
