The agar plate with the –pGLO LB / amp add no bacteria living in it because it wasn’t ampicillin resistant. But on the other hand the +pGLO LB/amp had a colonies of bacteria because when there is the pGLO plasmid it makes the e-coli bacteria ampicillin resistant so that is the reason why there are colonies of bacteria on the agar plate. For the last agar plate left the +pGLO LB/amp/ara this agar plate is the one that genetically transformed this is the one that could glow under the UV light <Fig 3 bottom right>. The reason that it glowed is because of the arabinose gene on the agar plate, that arabinose gene is the gene that triggers the GFP gene to express
In this mixture, there are no enzymes present and therefore no products are formed. The reaction rate was rated 0, just as we anticipated. 2. The 2nd experiment was a mixture of 2 mL H2O2 and 0.1g Manganese dioxide. We can use the same principal we used for the first experiment, Manganese dioxide is not a protein, not an enzyme, it is a catalyst.
Protocol: Hyphal Tip Growth The null hypothesis is that mycalolide B will not have an effect on fungal tip growth and nuclear position. The alternative hypothesis is that mycalolide B will have an effect on fungal tip growth and nuclear position. 1. Take off the tape and remove a slide from petri dish that has an agar cushion that is smooth, flat and no bubbles. 2.
I believe that Odwalla, Inc. is responsible in part and not in wholly because after the regulations and FDA testing at the Dinuba manufacturing plant was reported to had found no evidence of E. coli O157:H7 that was found in its products, the only source led to the growers and suppliers. But I say they are in part because their company name is own every product that they sale and distribute. Even if the E. coli outbreak did not come from their manufacturing facility, the company still has to take responsibility into every product that may have caused any illnesses, in which they did with the E. coli bacterium outbreak. Odwalla did the correct thing in ordering a recall of all of their products containing the unpasteurized apple juice. In a situation like this as a company and a brand name you cannot be selfish, or money hungry, when the safety of innocent individuals is at risk.
In comparison of the descriptive chart and the comparative analysis sheet, 18 out 18 of the tests performed were alike. This data helped me identify this unknown bacteria and understand why it was that bacteria. Enterobacter aerogenes is a facultative anaerobic bacteria that is present in the intestinal tract of humans. This bacteria naturally occurs in soil and freshwater and is present on plants, sewage, and is an opportunistic pathogen present on human skin. Antibiotics can be used to treat the
DLK vs. the United States In order to override privacy concerns without a warrant, law enforcement must be in danger of losing evidence. In the case of DLK vs. the United States, federal agents suspected DLK of growing marijuana plants in his home. Since they had no physical evidence, officers used a thermal scanner to detect any unusual heat patters coming from the home. After scanning and finding a few of those patterns, a judge issued a warrant that resulted in the finding of over 100 marijuana plants. In this case, I believe the government took it too far because there was no warrant allowing officers to scan DLK’s home, there was no danger of losing evidence, and DLK’s fourth amendment rights were violated.
Eosin methylene blue and Mannitol agar plates will also be used to determine pH values. Test Three: Gram Stain – A basic technique which will help to distinguish between a Gram-positive and Gram-negative bacterium. Test Four: Catalase assay – Is to be used to determine whether the unknown bacteria will liberate free O₂ gas. Test Five: Oxidase assay – The cytochrome Oxidase will aid in determining whether the unknown bacteria has an absence of Oxidase or not. Test Six: Glucose assay – Whether an organism can respire or ferment glucose can be tested with this Glucose O/F medium assay.
They damage the gastrointestinal tract, heart and liver. There is no known antidote for African rue poisoning, but treatment recommendations include rest, clean water and high quality feed. (Wargo) The African rue is native to Africa and southern Asia. I haven't found definite answers to validate if these plants cause problems in their native lands. I would think some of the health risk involved with this plant will be the same in its native land.

When Tom puts on the Ring, nothing happens. My first thought about this was that Tom is too powerless for the Ring to work. However that turned out not to be the case since Tom was described as the “master of wood, water and hill”. Later, the book mentions that Tom “is his own master. But he cannot alter the Ring itself, nor break its powers over others.” The importance is in the fact that no human or object has any power over those who are their own masters.
