Microbiology-2460 Lab-003 March 31‚2008 Lab Report-Escherichia coli Abstract The purpose for this lab report was to identify and inform of an unknown bacteria that has been causing a patient to have lower abdominal and pelvic pain. To obtain the identification of this unknown bacterium‚ several biochemical tests needed to be performed in order to prescribe the correct medication to treat and cure the symptoms. Introduction In a lab today‚ I am to identify an unknown bacterium that is

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

Energy Lab On November 13th‚ we did a lab to learn about energy. The definition of Kinetic Energy is energy of movement. The definition of Gravitational Potential Energy is energy in an object due to its positioning. The question that we had to answer was whether of not we could calculate the Gravitational Potential Energy and Kinetic Energy of various objects in different locations. To do this lab we had to first weigh the given objects. For this time‚ we weighed : a marble‚ a bouncy ball‚

LAB 12 Introduction In this lab you will use the Wireshark packet analyzer to capture and display the control information and data stored in packets transmitted over a network. Wireshark collects network traffic data and creates files that display packet header information in a layered format like that used by the Internet model. These layers can be expanded to view details that may prove helpful in determining the source of problems that your network might be experiencing. Creating filters that

LabMr.P/Pd. 63/17/14 Osmosis and Diffusion Lab Osmosis is a process where molecules pass through a semi permeable membrane from a less concentrated solution into a more concentrated one‚ equalizing the concentrations on each side of the membrane. Diffusion is the spreading of something more widely.During the osmosis and diffusion lab I tested what happens to a fresh egg when osmosis and diffusion across membranes. The eggs were placed in vinegar‚ distilled water‚ and then lastly syrup. The

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

Yak Lab Natural selection is the process by which favorable heritable traits become more common in successive generations of a population of reproducing organisms‚ and unfavorable heritable traits become less common. Natural selection acts on the phenotype‚ or the observable characteristics of an organism‚ such that individuals with favorable phenotypes are more likely to survive and reproduce than those with less favorable phenotypes. If all the offspring that organisms can produce were to survive

iron powder. Para-aminophenol crystallises out from the mother liquid which is subsequently centrifuged. Para-aminophenyl crystal is then reacted with acetic anhydride to produce pure paracetamol. The reactions are summarised as shown below: Lab scale manufacture Paracetamol can be easily prepared in the laboratory using phenol. Phenol reacts with sodium nitrate and separate para nitro phenol from outho nitro phenol. Then para nitro phenol is converted into para amino phenol using sodium
