Roles of microbes in DNA research Activities of microorganisms are very important to almost every sector of concern to mankind. From a perusal of the foregoing topics‚ one can find applications (uses) of microorganisms to agriculture‚ forestry‚ food‚ industry‚ medicine‚ and environment. The scope and significance of microbiology has enlarged manifold‚ particularly when importance of environment was realised globally and the word environment was used in a much wider sense in terms of totality to

The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so

INTRODUCTION As for the visual documentation of a living or dead specimen‚ digital photography has largely replaced traditional illustrations of the living specimen as the standard method of recording the colour and anatomy of the specimen in the field today. Earlier traditional illustration (coloured and black and white) are still considered scientifically important because they can stress fine anatomical features that are often obscured by liquid. Even today‚ these earlier traditional illustrations

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

things‚ that if the force of the egg doesn’t have something to fall into‚ like cotton or balloons‚ then it will break‚ because the force needs to be shared or it takes over the egg. With that‚ I understood a basis of how the device should be. This lab is designed to be very innovative with making devices so that nature can be defied. An egg that is supposed to break on contact from seven meters up will be safe and won’t break. The egg drop showcases endless laws of physics‚ and it also encourages

Introduction There are two groups of reflexes in the human body‚ with two ways to categorize each of them. Reflexes can either be inborn and connected through the nervous system‚ or they can be learned through practice. Another way to explain a reflexive category would be autonomic reflexes or somatic reflexes. Autonomic reflexes are those which are unaware to us and act on visceral organs of the body‚ whereas somatic reflexes involve skeletal muscle stimulation. Both types of reflexes are put into

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
