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

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

However‚ through the growth of the city‚ the expansion of the government‚ and the emergence of consumption and leisure throughout the economy‚ the city was able to recover to make the city stronger than ever. The book‚ “The Bronx is Burning” by Jonathan Mahler‚ clearly exemplifies and goes into much detail about the trials and tribulations that the New York City people were going through at the time. It delves into politics‚ the economy‚ sports‚ health and public safety in a time of

William Faulkner’s work “Barn Burning” is a great example of how authors can connect his writing with the reader. I observed that Faulkner gives us the duty to figure out each situation along the story. He introduces a problem‚ provide the details‚ but doesn’t conclude with a resolution. To me‚ it sounds as if he wants us to draw our own outcome. For instance‚ when Sartoris betrays his dad‚ Mr. Snopes gets killed‚ but we don’t know for sure what happens after it. In order to satisfy our ending‚

Lab #5 Chemical Reactions & Balancing Equations Objectives Observe and classify several chemical and physical changes. Give evidence for the occurrence of a chemical reaction. Write a balanced equation for a chemical reaction. Identify a reaction as a combination‚ decomposition‚ replacement‚ or combustion reaction. Background Physical properties can be observed without changing the chemical composition of the substance. Common physical properties that can be measured without changing the chemical

Purpose Name Due Date Clothespin Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally‚ muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the

Determining whether the God you praise and worship is choleric because of your presence by the sins you’ve created is a never ending battle in the 17th-18th centuries. Upon the Burning of Our House is a poem‚ with nine stanzas‚ written by Anne Bradstreet explaining her understanding and able to live and learn from sin with God. Sinners in the Hands of an Angry God is a work‚ written as a sermon‚ by Jonathan Edwards who preaches to all the non-Puritan sinners‚ that if they don’t convert and take blame
