Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil

Anxiety Lab Report Abstract: The aim of this study is to investigate the relationship between cognitive anxiety‚ somatic anxiety and self confidence in two different situations; non-stressful and stressful. It is to examine the effects on anxiety of a simple golf putting task. The stressor used in this experiment can be described as situational‚ namely the stressor of social comparison‚ the type of stressor that leads many performers to question their own ability which in turn evokes symptoms

that cigarettes release more then 20 carcinogens know to promote lung cancer into your body. (Hecht‚ 2010). When looking at the cilia exposed to cigarette smoke in this lab it is seen that they have been greatly slowed down when compared to the uncontaminated cilia‚ and parts of the cells are covered in tar from the tobacco. For this lab it was hypothesized that smoking will inhibit the ciliary action and lower the quality filter the greater affect will be exhibited by the effected cilia. The prediction
