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

Imagine a class where one can have fun and learn a much needed skill--that class is English Composition I. I have met my goal of becoming a better writer during this class. I did it by evaluating myself and learning from my mistakes. During my time in English Composition I‚ I have improved my writing through the advertisement analysis‚ the comparative analysis‚ plus the narrative‚ and the argumentative essays. The first essay I wrote was an advertisement analysis. I chose three aspects that helped

Determining the Limiting Reactant and Percent Yield in a Precipitation Reaction Objectives: Observe the reaction between solutions of sodium carbonate and calcium chloride. Determine which of the reactants is the limiting reactant and which is the excess reactant. Determine the theoretical mass of precipitate that should form. Compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. Materials: Balance 0.70 M sodium carbonate solution‚ Na2CO3(aq)

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

(dialysis tubing). The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration in the attempt to reach homeostasis in different circumstances. Introduction: The main purpose of this lab was to observe diffusion and osmosis. This is demonstrated using dialysis tubing and a combination of monosaccharaides‚ disaccharides‚ water (H20)‚ and sodium chlorine

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Opiate addiction comes in many different forms of abuse with many different kinds of people. There are three types of characterized reasons which can keep a person adducted to the opiate like the physical dependency‚ psychological dependency and the social context of the dependency. First of all‚ opiate addiction occurs after long-term use of the opiate and that person becomes physically dependent on it. Dependence on the opiates drug alleviates physical pain and allows those suffering from

Down with the Top Ten Percent Many colleges try to have a racially diversified environment by using affirmative action. Some colleges used the point system which would give an edge to minorities over Caucasians. The supreme court of Texas prohibited colleges to use affirmative action. When affirmative action was prohibited‚ minority enrollments at colleges decrease. To racially diversify colleges‚ Legislature passed the top ten percent rule. The top ten percent rule states any high school
