SCOPE OF MICROBIOLOGY: What is Microbiology? | � Microbiology is the study of microorganisms� Microorganisms‚ roughly‚ are living things that are too small to be seen with the naked eye� Microorganisms cannot be distinguished phylogenetically from �macroorganisms� (see variety of microorganisms‚ below)� Microbiology is more a collection of techniques: aseptic technique‚ pure culture technique‚ microscopic observation of whole organisms‚ etc.� Microbiologists

TITLE Lab #4 Soil –vs- Water Microbiology INTRODUCTION There are 4 learning goals for this lab: 1. Collect samples and compile data from at least 2 sources (soil; water) of your choice. 2. Identify at least 2 Prokaryotes (bacteria) and 2 Eukaryotes (fungus) in your samples. 3. Research the importance of bacteria and fungus to Earth in a non-medical context. 4. Compile a high-quality‚ 3+ resource (excluding the lab worksheet)‚ MLA-cited in-text laboratory report using the scientific method

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

pleiotropy is the single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits. Mutation in this type of gene will simultaneously affect more than one trait. An example is phenylketonuria‚ a human disease caused by mutation(s) in a single gene that codes for the enzyme‚ phenylalanine hydroxylase. The disease is characterized by mental retardation and reduced hair and skin pigmentation. List and explain other factors that

photochemical change. The light required for a photochemical reaction may come from many sources. Giacomo Ciamician‚ regarded as the "father of organic photochemistry"‚ used sunlight for much of his research at the University of Bologna in the early 1900’s. One of the oldest and most studied photochemical reactions is the photoreduction of benzophenone (diphenyl ketone). It was discovered that solutions of benzophenone are unstable to light when certain solvents

Increasing evidence suggests that the alarming rise in allergic and autoimmune disorders during the past few decades is at least partly attributable to our lack of exposure to microorganisms that once covered our food and us. As nature’s blanket‚ the potentially pathogenic and benign microorganisms associated with the dirt that once covered every aspect of our preindustrial day guaranteed a time-honored co-evolutionary process that established “normal” background levels and kept our bodies from overreacting

Open Reading Frames * (ORFs) are regions with no stop codons. All genes reside in long open reading frames * Note that stop codons in other reading frames have no effect on the gene. * Can be searched in the genome sequence. Valid only for prokaryotes and lower eukaryotes. Protein Sequencing vs. DNA sequencing * We compare protein sequences‚ not DNA‚ because protein is more conserved in evolution than DNA * The organism’s survival depends on the protein being

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be
