I am taking a chemistry class and we have been asked to write a chemistry paper for the final assignment. When I started thinking about a topic the wheels started to turn. I than found myself asking the question, what is chemistry exactly? Chemistry is the scientific study of interactions of a chemical substance that are constituted of atoms or the subatomic particles that include protons, electrons, and neutrons. Atoms combine the produce molecules or crystals. Chemistry is often called "the central

Pollution is the introduction of contaminants into the natural environment that cause adverse change.[1] Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Today, it is becoming a serious crime to pollute the air and water. -------------------------------------------------

Structure and Function The word protein was first coined in 1838 to emphasize the importance of this class of molecules. The word is derived from the Greek word proteios which means "of the first rank". This chapter will provide a brief background into the structure of proteins and how this structure can determine the function and activity of proteins. It is not intended to substitute for the more detailed information provided in a biochemistry or cell biology course. Proteins are the major

Clara Skepple Miranda Wilby, Sarah Cavanagh Thursday, March 3 2016 Observing Diffusion and Osmosis INTRODUCTION: Related Theory: The cell membrane is the outermost boundary of the cell, made up of proteins and lipids. This membrane holds the cell together and establishes the movement of materials that go into and out of the cell. This is a selectively permeable membrane: a barrier that allows some molecules to pass through, but prevents other molecules from penetrating (1). Passive transport is

Smart Urinary Biosensor (Biomedical Engineering) Introduction With the increasing cost in providing healthcare to patients with chronic conditions, new strategies need to be developed to provide monitoring and support in a more distributed, noninvasive and remote atmosphere. Smart urinary biosensors permit the internal biologically-controlled mega-network controlled by the central nervous system communicates with an external body sensor using a wireless communication technology (Thomas

Food Web Diagram Brandy Meilhon SCI 230 Week 9 Create a diagram in which you illustrate the energy flow among organisms of a food chain in a particular ecosystem. Select an ecosystem, such as a temperate forest, desert biome, or the Everglades. For the ecosystem, I chose The Great Barrier Reef, Australia. Determine the interdependency of life in your ecosystem by examining its organisms. Include the following: List the organisms that can be found in your ecosystem. 1. Dolphin

is a very useful method to analyze chiral substances. The magnitude and direction of rotation of the plane of lineraly polarized light by a chiral compound is a specific physical property of the compound that can be used to characterize it. Most biomolecules are chiral and hence rotate polarized light. In this experiment you will study the optical rotation of a series of mixed monosaccharide solutions and determine the relative concentrations of them. The instrument used to study optical rotation

Metabolic Syndrome and Cardiovascular Disease According to Mayoclinic.org ‘Metabolic syndrome’ (also called dysmetabolic syndrome or syndrome X) is defined as ‘a cluster of conditions — increased blood pressure, a high blood sugar level, excess body fat around the waist and abnormal cholesterol levels — that occur together, increasing your risk of heart disease, stroke and diabetes.1’ Metabolic syndrome is becoming increasingly common and is now recognised as a major causal factor in cardiovascular

Protein misfolding – hidden enemy of the brain Protein has always been a fundamental and irreplaceable biomolecule that builds up life. The studying of protein, proteomics, not only allow humans be aware of ourselves and the biosphere around us but also set the foundation for scientists to approach solutions for many human’s health problems. Among those many health issues, diseases that are associated with central nervous system raise the most concern. Many of these nervous disorders, surprisingly
