Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

NAME: PRAJWAL BHARADWAJ Ampicillin‚ Vancomycin‚ and Tetracycline Effectiveness on Gram Positive and Gram Negative Bacteria. INTRODUCTION: Bacteria are microbial organisms which are present in various environments. Many bacteria are good and help humans synthesize materials and assist in biological processes‚ such as digestion. However‚ some bacteria can cause harmful diseases. When harmful bacteria infects the body‚ people take antibiotics in order to suppress bacteria. Different antibiotics have

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

Our main goal was to test organisms’ resistance and susceptibility to bacteria‚ and whether the cell wall of bacteria exposed the membrane to pathogen or protect it from pathogens. I thought P. aeruginosa was gram-positive and therefore it would be susceptible. That was my hypothesis.We divided antiseptic agar plate into quadrants and divided antibiotics agar plate into six areas. We wrote the organisms’ name‚ date‚ and the temperature on the bottom of the agar plates. For antiseptic‚ our group used

Crystallization: Lab Report Theory/Introduction The purpose of this lab is to understand the concept of purification through crystallization. Crystallization is the process of purifying a substance‚ with the most adequate solvent. The process of crystallization came to be based on the principle of solubility. First‚ we must choose a solvent. The solvent is crucial to crystallization because it’s what will allow impurities to dissolve. Therefore‚ when selecting a solvent it is important that it

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic
