BIOCHEMICAL IMPORTANCE OF WATER Of all the simple chemicals that are found in abundance on Earth‚ only water is liquid under normal pressure and temperature. When life first appeared on planet Earth‚ water has played an important role in creating the first organic compounds. The organic compounds later‚ formed the first prokaryotic organisms. Life began‚ as the modern theories support‚ in water and developed for three billion years in it before spreading on land. It is no coincidence that the

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

necessity of proteins for life is unequivocal‚ not only do they help to form the structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell and is named according to the substrate they specifically affect. An enzyme works best under optimal conditions pertaining to temperature‚ pH level and salt concentration1

Lab 2 Tensile Test Abstract The aim behind this experiment was to put Mild steel‚ copper and aluminium through a tensile test‚ with Mild steel being tabulated and graphed to show its properties and how they could be used in the real world. Introduction/Theory Tensile testing is one of the most simple and widely used materiel tests available. It is used to characterize the mechanical properties of the material and has direct implications on the design and construction of the end product. This test

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis? One way to increase the knowledge of hazards in the workplace is to conduct

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic
