    and widespread in the environment. In this lab‚ we undertook to determine the differences in the agars being used and the different colony count observed. After taking four different samples of microbes from the environment and swabbed them in two different plates one with nutrient agar and the other with sabouaud dextrose agar. After the microbes had incubated for 48 hours no results were discovered from the swabs we had taken from the environment. This lab further investigates the different swabs

In conclusion‚ although there were sources of error‚ the hypothesis was proven correct by the efficiency of the procedures and the accuracy of the results obtained. Introduction In chemistry‚ titration is a common laboratory technique that is used to determine the concentration of a substance in a solution. It is performed by neutralizing the solution with the same volume of either an acid or base with a known concentration. (“Titration.” American Heritage Science Dictionary

    Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

    varying temperatures are targeted towards being at 10ºC‚ 20ºC‚ 30ºC‚ 40ºC‚ and 50ºC. It is highly improbable that each trial for each of the 5 different temperatures will be the exact temperature that was targeted‚ so it’s just important that you end up having a temperature fairly close to the targeted temperatures so that the rates of reactions that you do receive are as correct as possible. The rates of reaction will be obtained using an apparatus that will guide the carbon dioxide gas being produced

    combination will result in a unique ratio‚ thus allowing us to compare unknown samples and discover their identity. The Rf value is essentially the rate the dotted sample will move in accordance to the solvent rising up the chromatography strip via capillary action. As the solvent gets sucked up to the solvent front‚ the sample dissolved into the paper will “grab” onto the moving solvent. Polarity plays a huge role on the ratio‚ as it affects the substance’s ability to migrate with the solvent. A higher

    Abstract There are many methods employed to precipitate proteins out of solution. In this experiment we manipulated many physical and chemical variables in order to achieve purification of a protein via precipitation. In the first part of the experiment we purified the protein casein by modifying it’s pH. In the second part of the experiment we manipulated the ionic strength of albumin in egg whites‚ in a process called salting out. By manipulating these chemical properties we were able to

    Adriana Rempson Mrs. Steeger AP Biology-7 10 October 2012 Transpiration in Plants Abstract: Our group wanted to see how transpiration would happen in plants when they were in different environments. The different environments we used were humidity and room environments. We measured transpiration using the whole plant method. Our results showed that the plants in a humid environment had greater transpiration rates than the plants in the room environment. Introduction: Pants absorb and
