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

afflicted‚ yet in the movie‚ it is just a playful story about some fictional characters. "One pill makes you larger‚ and one pill makes you small." The interpretation used in the passage‚ is that Alice was using some sort of drugs. She was hallucinating‚ of growing and shrinking rather than doing so. "And the ones that mother gives you don’t do anything at all"‚ suggests that when you are "prescribed" a pill‚ you are meant to have that drug. If the drugs come from someone

the five pill bugs found their way to the leafy environment. However‚ most of their time was spent in the section of soil. For the second part of the experiment where we tested each of the pill bugs separately‚ we found that the bugs spent most or all of their time in the soil environment‚ therefore‚ composing the answer to the question of their most favored environment. The chart in image two contains the data found in the first part of the experiment. After allowing the pill bugs to roam freely

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

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

The materials used for this lab were filter papers‚ a choice chamber‚ eight pill bugs‚ water‚ and tin foil. The first step of the process is to trace and cut the filter paper so it fits neatly within each side of the choice chamber. Then‚ put water each filter paper and place the damp filter paper into the choice chamber. The damped filter paper causes the pill bugs to not be able to crawl under the paper and therefore disrupting the results. Four pill bugs should be placed on either side and one

A Pill Bugs Preference to a Rough and Smooth Environment The experiment that I decided to look into‚ was finding out if an Armadillidium vulgar‚ also known as a pill bug‚ would have a preference to the two types of environments that I had decided to experiment with. The two types of habitats that I choose were saran wrap which is smooth and sandpaper that is rough. How I set up this test was I had a choice chamber with a barrier in the middle that had a little door cut out of the bottom center
