Section B 1. A) What properties of chromosomes suggested to early geneticists that they might harbor the genetic material? What experiments confirmed these suspicions? Chromosomes was known to possess deoxyribonucleic acid. The genetical material was expected to have the stability but still capable of accepting sudden and permanent changes to adapt to evolution. Experiments that confirmed the suspicions were done by: • Griffith- demonstrated non-virulent strains of bacteria turned virulent when

CHAPTER I INTRODUCTION RESEARCH BACKGROUND This research is about the extraction of keratin protein from chicken feathers using strong fluid extraction process. This extraction procedure utilized a dissolvable as lessening specialists to separate salt linkages, disulphide bond and hydrogen bond of the keratin fiber to break down into protein. Thus, it will likewise diminish the steadiness of keratin strands in the strong structure found in feathers. Proteins are polymer formed by one or

Indoor air pollution exists in various forms, some of the common pollutants ranging from carbon monoxide, nitrogen oxide produced by the gas stoves in households, particulate matter to environmental tobacco smokes (ETS) and many more. For the past few years, there is scientific evidence that prove that the air inside our home or building is more polluted than outdoor air. In addition, the long-time exposure to these indoor pollution has increased the risk in health problems in human for example eye

1 Cadmium is a soft, malleable metal that is found in the earth's crust. Cadmium emissions can originate from several anthropogenic sources from the burning of fossil fuels or trash, smoking cigarettes, pesticides, or manufacturing activities. As it is naturally found in the earth, it obviously can be found naturally. Natural sources of cadmium include the weathering of rocks to volcanoes and forest fires to certain foods (Lenntech, 2011). Health effects of cadmium are wide-ranged. Acute effects

What is the main feature of the topic? The main feature of this topic is the Reversible Addition-Fragmentation chain Transfer (RAFT) polymerization of N-acryloyl-L-phenylalanine (A-Phe-OH) where the carboxylics acid functional group is kept intact. Furthermore this is achieved without the use of a protecting group, such as methyl esters, as seen below. Figure 1: Preservation of Carboxylic Acid Moiety This article further examines the effect of chain transfer agents (CTA), solvents, temperature

Trans fatty acids are part of the macromolecule group lipids. Lipids consist of glycerol and fatty acids. Lipids are long hydrocarbon chains of carbon and hydrogen atoms which are bonded together. Hydrocarbon chains that consist of solely single bonds throughout are called saturated fats. A hydrocarbon chain
