Most education systems rely on examinations to encourage children to study‚ but as a result children suffer from too much stress and they never learn to be creative. Therefore‚ examinations should be abolished. Do you agree? If any student were asked whether he would like examinations to be abolished or not‚ nine out of ten would readily answer “Yes.” It is true that most students cringe from tests‚ but it is a fact that exams are an indispensable tool for education. Tests not only help students

Title: Microorganisms are everywhere. Tara Brady Dt201 Objectives: In this experiment‚ my aim is to prove that microorganisms are present everywhere and that nowhere in our everyday lives is free from bacteria. I expect this to be the case as even germicide soaps do not kill all bacteria present on our skin; likewise household cleaning products are incapable of killing all microorganisms present. I am doing his experiment to verify the concept that microorganisms are everywhere and I most certainly

literally microscopic organisms‚ which can only be seen properly with the aid of a microscope. These include bacteria‚ microscopic fungi (moulds) and protoctists. Although viruses‚ which are even smaller than bacteria‚ are generally considered to be non- living entities‚ they might also be included here as they are important disease-causing agents. Micro-organisms are the most numerous organisms in any ecosystem. There are about 159‚000 known species‚ although this is thought to be less than 5% of the total

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is

A Survey of Eukaryotic Cells and Microorganisms HISTORY OF EUKARYOTES: 1. Evidence indicates that the first Eukaryotic cells first appeared on the earth approximately 2 billion years ago. Fossilized cells appear in shale sediments from China‚ Russia and Australia the date from 850-950 million years ago. 2. Biologists have discovered evidence to suggest that the eukaryotic cell evolved from prokaryotic organisms by a process of intracellular symbiosis. 3. Some of the organelles that

prevention of the transfer of amino acid for growing peptide chains which leads to the inhibition of the formation of bacterial protein. (Michigan State University‚ 2011). Chloramphenicol is a broad-spectrum antibiotic. (Hitner et al.‚ 2016). Bacterial microorganisms become resistant by the inactivation of chloramphenicol through the enzyme acetyltransferases. (Rang et al.‚ 2016). Chloramphenicol resistance are very common in Staphylococcus spp. such as Staphylococcus aureus (S. aureus) and Staphylococcus

Colonisation is when microorganisms become a part of the normal internal flora. These mircoorganisms are not harmful to the human‚ but when they reproduce and multiply they join the natural flora of the body and they all live together. Infection is when a pathogen (infection causing microorganism) invades the body and start to reproduce in any tissue of the human. Examples of infection include the common cold‚ skin infections (warts) and gastroenteritis. Disease refers to a disruption in the sturture

Introduction: Microbes‚ also called microorganisms‚ are minutes living things that individually are usually too small to be seen with the unaided eye. The group includes bacteria‚ fungi (yeast and molds)‚ protozoa and microscopic algae. It also includes viruses‚ those noncellular entities sometimes regarded as straddling the border between life and nonlife. People tend to related these microbes only with major disease such as AIDS‚ uncomfortable infections‚ or such common inconveniences as spoiled
