Unknown Report Emily Juhl Section – 3 April 15‚ 2013 Unknown #8 Family: Enterobacteriaceae Genus: Serratia Species: Marcescens Abstract Microorganisms are constantly finding ways to resists to antibiotics. For this reason‚ it is important to test and observe unknown organisms in the lab to continually improve the health and well being of society. The objective of this report was to first isolate a single colony of an unknown culture on a LB agar plate. From

Name: Nikia Martinez Class: Biology 240L L3-1201 Assignment: Electrocardiography Lab Report Due: April 3rd 2012 Professor: Dr. B. Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

University of Phoenix Material Roderick Tabigne Respiratory System Lab – Week Six Introduction The respiratory system consists of the upper respiratory tract (the nasal cavity‚ pharynx‚ larynx‚ trachea‚ and bronchi) and the lower respiratory tract (the lungs). As you learn about the various diseases that affect the respiratory system‚ it is important for you to understand the structures that can be affected by disease. Complete this lab to become familiar with a healthy system and to identify diseases

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

Bioinformatics Lab Report Hypothetical Phylogenetic Tree: Using a cladistic approach‚ we constructed a hypothetical phylogenetic tree of many different plant taxa by comparing their morphologies. We first decided to sort the various types of plants into groups based on morphological features. After sorting these plants into five different groups we began to determine how the plants differed from eachother in the group and what features set them apart. From this we started to create

Lab Report Enzymes (must be typed) Name: Amanda Gallegos Date: 2/15/15 Section: BIOL 101GL What is the Hypothesis of this experiment? (3 points) -The highest temperature will affect the reaction rate of enzymes. What is the dependent variable? (1 point) -Change of rate/product/color/absorbency. What is the independent variable? (1 pt) -The temperature. Explain in detail the procedure that you followed (including amount of substrate‚ enzyme etc‚ and the whole procedure including incubation times)

the percent yield by dividing the expected yield‚ the amount of product that should be produced based on your stoichiometric calculations‚ by the actual yield‚ the amount of product that is experimentally obtained from a chemical reaction. In this lab‚ I have determined the reaction for mixing two reactants together; I measured out 0.005 moles of each reactant‚ lead (II) nitrate and potassium chromate. I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants

objects‚ and the petri dish is a nonliving object. There are many different types of antibiotics; however‚ they all have one thing in common: the ability to inhibit and abolish the growth of microorganisms by destroying their cell wall. According to Microbiology Online‚ antibiotics are the most effective bacterial inhibitor because they take advantage of the difference between bacterial cell’s structure and the host’s cell’s structure. Nevertheless‚ ever since the Alexander Fleming’s discovery of Penicillin

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)
