Gram-positive bacteria

greek; monas = single unit, latin). “Monas” was used in the early history of microbiology to define single-celled organisms. In 1786 Otto Friedrich Müller, from Copenhagen, classified the bacteria and named the pseudomonads, they came into the group of vibriones (which was defined as group of shaking bacteria). Many years later it was detected that Pseudomonas are motile. They therefore were given the name “Pseudo”, because they appeared to be shaking but in reality they were motile. Because of…

Following the Ways of the Scientific Method The scientists solved the Elkhorn Coral mystery using the scientific method by following each step of the method to come to a conclusion as to what is killing the coral. The followed the steps precisely so that would not make any errors during their trials. They started with the first step of the scientific method, making an observation. Paragraph 7, sentence 1 of “Underwater Whodunit: What’s Killing Florida’s Elkhorn Coral” states, “Hot on the trail…

In order to collect accurate data from an experiment, it is important to evaluate the environment that the lab will be taking pace. While my lab partners and I were doing this, we checked to see if the workspace is clean and clear of an unnecessary or harmful objects, especially food. Then our second step was to gather all the necessary supplies for the experiment. This included, a microscope, three glass microslides, alcohol, caffeine, and water, four pippets, then finally three water fleas.…

Introduction Termites, Isotera, are known to react to the exposure of the chemical substance found in ball point pens. Naturally, termites will follow any trail made up of pen ink. This specific observation was tested and carried out by Sim et al. They “investigated how termites select the direction of movement at an artificially-designed branching node, by making chemical trails on filter paper, drawing lines using a ballpoint pen which contained the chemical substance that induces the termite…

To determine the effect of the proximity of the dam on fish distributions downstream, I will collect data at three locations along the Monongahela River, moving downstream from the dam (Site 1, Site 2, and Site 3 in Figure 1.A). I will repeat this two times on two different days of similar weather patterns for a total of $110 in anticipated costs. At each site, I will collect a variety of variables. For starters, I will collect an indication of water clarity using a secchi disk at each site for…

Three agar slants and three nutrient broths were inoculated with Staphylococcus epidermidis using aseptic techniques for transferring samples from broth, agar, and plate cultures. A sterile inoculating loop was used to transfer a loopful of culture from the culture to the sterile media. The lip of the culture tube and inoculated media tube was flamed before and after transfer. The inoculating loop was reserialized after transfer was complete. An agar deep transfer of S. epidermidis was also done…

electrophoresis, we will observe their rate and direction as the agarose gel is separating the mixture of dyes into their individual components. They will differ in structure, chemical composition, and amount of energy carried by each. Since dye F has a positive charge, and the other dyes A-E are negatively charged with a neutral pH, then we will be able to observe the molecules move to the opposite side on dye…

believe GMO’s are bad for humans, unless you’re sick which I’m not, I see GMO’s as a bad thing. GMO’s or “genetically modified organisms” these could range from animals to plants that have been genetically altered with DNA from plants, animals, bacteria, and viruses. The American Academy of Environmental Medicine (AAEM) advises medical physician’s to recommend non-GMO diets for all patients. Doctors are saying not to wait to take actions, especially if you have little children. GMO’s hit the…

Bacteria are one-celled organisms. When looked at under a microscope, they appear to be balls, rods, or spirals. Contrary to popular belief, most bacteria are actually good for other organisms. Under 1% of bacteria on Earth cause disease, and the bacteria that do can usually be treated with antibiotics (“Bacterial Infections: Medline Plus,” par 1). The common image of bacteria is that they are all horrific organisms that cause disease. While people should most definitely wash their hands to…

lab, students will be taking the pGLO gene, which makes the protein Green Fluorescent Protein (GFP), commonly found in a species of jellyfish, which glow (N.d., p. 32). Theoretically, when the pGLO gene is inserted into the E. coli bacteria, then the E. coli bacteria will also…
