Antibacterial Agents Inhibit the Yield of Saccharomyces cerevesiae Andrea Peña Biology 1401-C Department of Biology‚ The University of Texas-Pan American‚ Edinburg‚ Texas 78539 October 22‚ 2012 Abstract – The problem that led to this experiment was that when antibiotics were mixed with yeast cells‚ the antibiotics decreased the yield of yeast cells. However‚ this is unexpected result because yeast is not a bacteria and therefore antibiotics should have no effect on them. The hypothesis that was

Silicon dioxide (SiO2) is one of the most common oxides on the surface of earth. Like most oxides‚ it adopts a polymeric structure. Оксидите се хемиски соединенија што содржат најмалку еден атом на кислород и еден атом од друг хемиски елемент во својата формула. An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygenatom and one other element[1] in its chemical formula. Metal oxides typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth’s crustconsists

Project – Scientific Method Professor David Anderson Michelle Edwards 06/30/2015 Scenario 1 We are having a potluck luncheon for work at my house and I was chosen to make lasagna. As I was preparing my favorite lasagna recipe‚ I noticed that I’m missing that one important ingredient‚ which is the ricotta cheese and I only have an hour before my guests arrive. First thing that comes to my mind is what do I do? Without realizing I’ve actually began utilizing the scientific method‚ which is

Webster dictionary defines scientific method as the collection of data through observation and experiment‚ and the formulation and testing of hypotheses. Basically‚ the scientific method has five steps‚ in which each step is crucial to finding answers. The Scientific method is used in the Human Service industry to help find solutions to social through Quantitative and Qualitative research which this paper will thoroughly discuss. The first step in the Scientific method is to define the problem. In

knowledge is scientific knowledge‚ and that such knowledge can only come from positive affirmation of theories through strict scientific method. The main thrust of the positivist research tends to follow certain scientific and measurable methods to conduct a research. A positivist approach is one that is considered objective‚ detached and if I may put that way‚ structured by the researcher’s views who test a hypothesis. It is usually associated with quantitative data collection methods and statistical

Lab report June 11‚ 2013 Biology 123 Professor K Title: Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme

investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment

Educational Research and the Scientific Method Phoenix University April 12‚ 2010 Education and the Scientific Method Research can be defined as any compilation of facts‚ evidence of data‚ information and proof of truth for the advancement of knowledge. It can be defined as the pursuit for statistics‚ figures‚ numbers or reports or any methodical investigation to establish concrete facts. Research must begin with a clearly defined goal and not be based on assumptions. The information gathered

General Biology I Spring Semester 2013 Lab Report Name: Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme
