H R Diagram Main Sequence Stars Absolute
527 wordsThe Hertzsprung-Russell Diagram or, the H-R Diagram for short, is a graph which plots stars according to their temperature and absolute magnitude. This graph reveals a pattern, which in fact is quite interesting. The H-R Diagram is named for the two astronomers, Ear Hertzsprung and Henry Russell, who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. One key purpos...

Amount Of Energy Oxygen Atoms
1,983 wordsPlanning In this investigation I will be burning alcohols to heat up a beaker of water. I will be burning five alcohols, methanol, ethanol, propanol, butanol and pentanol. The aim is to find out how much energy is produced when burning these alcohols. An alcohol is a series of organic homologous compounds, with the general formula Cn H n + 1 OH´ . Alcohols react with oxygen in the air to form water and carbon dioxide. The reaction that is involved in burning alcohols is exothermic because ...

Rate Of Reaction Bunsen Burner
2,301 wordsFor this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...

Carbon Atoms Specific Heat
4,299 wordsI am going to investigate the difference in enthalpy of combustion for a number of alcohols, the enthalpy of combustion being the enthalpy change when one mole of any substance is completely burnt in oxygen under the stated conditions. I will be attempting to find how the number of carbon atoms the alcohol contains effects the enthalpy change that occurs during the combustion of the alcohol. Method I plan to measure the enthalpy change by burning the alcohol, using a spirit burner, I will then u...

This model will have two particular simplifying features, in that it will focus exclusively on the demand side of the economy, and it will not include either government activity or the foreign sector. ? In order to construct this model, we will assume that all prices and wages are fixed within the economy, and that there are ...

Lab Manual E Coli
1,139 wordsGene Regulation Using the Lac Operon Abstract Gene regulation in cells has been studied extensively in both eukaryotic and prokaryotic organisms. Gene control is employed as a way of saving the cell energy by only producing those enzymes it needs. In eukaryotes, genes are regulated so as maintain levels of cell specificity. In this experiment, the restriction of the production of the -galactosidase enzyme in the prokaryote Escherichia coli can be achieved by employing the lac operon. This operon...
