Silveira Date of Submission: September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

is because the fire fighters played a significant role during and after 9/11 in aiding the people and directing them to safety. They also spent many days desperately searching through the rubble for any survivors. It is these actions that classify the men as “real life” heroes‚ and with the aid of film codes the viewer will understand this and respond with feelings of pride and respect for the firemen at the scene of 9/11. Symbolic codes include how the heroes become victims of terrorism; they

Balance Sheet The biggest change in Abbott’s balance sheet can be seen in the composition of its asset accounts. In 2006‚ % of the firm’s assets were current‚ while 69% were of the long-term variety. In 2010‚ however‚ the portion of current assets increased by 7%. This increase in current assets is most visible in cash and short-term investments (4% in 2006 to 9% in 2010) and corresponds with a higher level of uncertainty in today’s economy.
