Lab Write Up Identifying an Unknown Microbe Gregory Howard 10E The isolation I was given two unknown microbes and asked to identify them. The first step was to isolate each microbe. I did this by using the streak method to apply each microbe to an enrichment culture. The enrichment culture provides conditions to enhance growth of a species. Obataining a pure culture makes it easier to identify and study a particular species. The macconkey agar plate which is used to isolate and differentiate

Trace of the Bolus MOUTH The mouth, also referred to as the oral or buccal cavity, is formed by the cheeks, hard and soft palates, and tongue. Forming the lateral walls of the oral cavity are the cheeks—muscular structures covered externally by skin and internally by non-keratinized stratified squamous epithelium. The anterior portions of the cheeks end at the lips. The lips or labia are fleshly folds surrounding the opening of the mouth. They are covered externally by skin and internally

2.3 Chemistry of water Water is a polar molecule The shape of a water molecule and its polarity make hydrogen bonding possible, A hydrogen bond is a weak attraction between a slightly positive hydrogen atom and a slightly negative atom. (They are partial charging) * Can occur between atoms of different molecule or within the same molecule * A single hydrogen bond is easily broken while multiple hydrogen bonds are collectively quite strong. * Help to maintain the proper structure

evolutionary relationship to species of cleaner shrimp Thor amboinensis to evaluating the promise and molecular taxonomy of individuals comparative to described taxa and DNA led discovery of novel species. Those aspects are rely on a solid taxonomic base, including sufficient sampling of disparity within species and enclosure proves the efficacy of mtDNA CO1 gene sequence based approach in recognizing fish species at a earlier pace.

IncorrectQuestion 1 0 / 1 pts Which of these is an example of homeostasis? Hummingbirds prefer to feed on nectar from red flowers. Homeostasis is the maintenance of the body's internal state within a relatively narrow range. When the dog's body temperature becomes too high, the animal feels hot. He opens his mouth, lets his tongue loll out, and pants until he feels comfortable again. A shark can detect even minute quantities of blood in the water. Venomous coral snakes and harmless

Determine concentration of enzyme stock solution, if unknown, by taking an A280 nm reading of a 1:100 dilution (in water). Use a total volume of 1 ml in the cuvette. • Dilute some of the enzyme stock with buffer A to make a 4 mg/ml solution. • Serially dilute the 4 mg/ml solution with buffer A to make working solutions of 400 µg/ml and 40 µg/ml. • Prepare 30 µl of each working solution for every sample The PI of the lab gives you a tube of enzyme and tells you the following before disappearing

well-established record of safety and efficacy.3 Although acetaminophen overdose is very rare in the context of its broad usage, overdose can be toxic and lead to acute liver failure.3 Preparation of acetaminophen involves treating an amine with an acid anhydride to form an amide.4 In this experiment, p-aminophenol (the amine) is treated with acetic anhydride to form acetaminophen (p-acetamidophenol), the amide. The chemical reaction for acetaminophen is as follows: 4 Procedure Procedure is
