FOREWORD: The world as we know it has changed drastically over the years. With the advent of technological and industrial advancement‚ life has become much easier‚ however‚ not without its share of negative consequences. One such consequence is that the quality of the air we breathe has deteriorated considerably- mainly as a result of human activity. Is this an acceptable price to pay for development? INTRODUCTION: This report seeks to identify the main industrial sources of air pollution in

The History of the Electric Guitar The desire to increase the sound of the guitar existed long before the development of electrical amplifiers and speakers. Musical performances in the 19th century were characterized by ever-larger concert settings and ensembles. Musicians needed louder and more powerful instruments‚ which became possible by using new materials and designs. The introduction of steel strings in the 19th century meant not only greater volume‚ but greater tension on instruments

1. water molecules have +0 charged ends and can form weak hydrogen bonds . water is said to be a dipolar molecule. 2. The basic uits of CO2 are monosaccharides ‚ characterized by the number of carbon atoms‚ e.g pentose sugars have 5 carbons 3. Two monossaccharids can link together to form a disaccharide . the bond between them is a glycosidic linkage formed in a condensation reaction 4. Starch is a polysaccharide composed of amylose and amylopectin. Its main function is as a storage

1. Definition of air pollution Air pollution is the introduction of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or cause damage to the natural environment or built environment‚ into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as
