Abstract
In this article, the writer discusses the crime of arson. The writer examines how such a crime can be detected. The paper first examines the chemistry of a fire in detail and then looks at how fires spread. The writer discusses how to differentiate arson from an accidental fire, by detecting the presence of accelerants.
From the Paper
"The crime of arson is the willful burning of someone else's property and the crime is more dangerous to human life than murder because statistically, murderers usually do not kill again but arsonists will continue to set fires until they are caught. Arson investigations are highly complex processes and unless conducted immediately valuable evidence may be lost forever. To determine whether a fire is accidental or a case of arson, it is necessary to understand the basics of the chemistry and behavior of fires. Fire is ... "

Abstract
In this article, the writer examines the general structure of enzymes. The writer discusses how enzymes act to speed up chemical reactions. The writer details the six major groups of enzymes: oxidases, lysases, ligases, isomerases, transferases and hydrolases.
From the Paper
"Enzymes are special proteins which act to speed up chemical reactions because many chemical reactions required for cells to function normally would not take place at the temperature and pH found in the body. The protein part of the enzyme without any co-factors or prosthetic groups attached is known as the apo-enzyme. Not all enzymes have co-factors or prosthetic groups. Co-factors are small inorganic or organic molecules which are required for enzymatic activity of the apo-enzyme such as the copper loosely bound to lysine oxidase ... "

From the Paper
"An antibody is a protein produced by lymphocytes of the immune system in response to the presence of a foreign antigen in the system. It usually binds to the foreign antigen and causes it to precipitate from the circulation. Antibodies can be purified in the laboratory and conjugated chemically bonded to a variety of substances including a fluorescent dye such as fluoresce-in. This conjugated antibody can then be applied to sections of tissue that have been lightly fixed or frozen so that the location ... "

Abstract
This paper answers a number of questions on general biology dealing with glycolysis, Krebs cycle, electron transport phosphorylation, respiration, mitosis, meiosis, crossing over, independent assortment and random fertilization.
From the Paper
"Cellular respiration is the process of oxidizing food molecules such as glucose to carbon dioxide and water. Kimball Energy is released in the form of ATP which is used for all the energy consuming processes of the cell. There are two stages to the process, glycolysis which is the breakdown of glucose from the diet to pyruvic acid and the complete oxidation of pyruvic acid to carbon dioxide and water. In eukaryotes glycolysis takes place ... "

Abstract
In this article, the writer offers a definition of the process of osmosis. The writer answers specific questions on the effect on cells of osmotic pressure. The writer then discusses the transport of large molecules into cells. In this paper, the writer examines thermodynamics and enzymes. The writer alos presents technical information in this regard.
From the Paper
"Osmosis is the process of diffusion of water molecules across a membrane. The contents of cells are basically solutions of many different solutes and the more concentrated this solution is the more solute molecules there are in a given volume and the less water molecules. Water molecules can diffuse freely across a membrane but only down a concentration gradient so water always diffuses from a dilute solution to a more concentrated solution. Osmosis can be quantified using water potential so it is possible to calculate ... "

»
Click here to show/hide summary
Abstract
This essay looks at how snow is formed. The writer discusses the factors which determine the structure of snowflakes. In this article the writer examines what makes snow melt. The writer also looks at the efficiency of different salts for melting snow. In addition, the writer discusses briefly the impact of snow on society.
From the Paper
"Snowflake Factors which affect snowflake formation include temperature, air, currents, humidity, which affect the size and shape of snowflakes and dirt and pollutants mixed in water which affect the crystal weight and durability in snow. Dirt particles make the snowflakes heavier which causes cracks and breaks in the crystals and make the snow melt more easily. In general snowflakes which are six-sided hexagonal shapes and are formed in high clouds, needles or ... "

Abstract
In this article the writer discusses prostate cancer. The writer also examines some of the biochemical research that is being carried out to try and determine the causes of this type of cancer. The paper looks at the oxidative stress on cells and the effects of androgen. The writer discusses NSAID-associated gene protein and some of the multi-drug resistance associated proteins.
From the Paper
"Prostate cancer is a disease of aging brought about by changes in cellular biochemistry which result in an imbalance in the pro oxidant-antioxidant balance and in the cellular response to androgen which this brings about. Many advanced cases of prostate cancer become resistant to chemotherapy making the prognosis for those men dismal. It has been shown ... "

From the Paper
"Friedrich August Kekule was born in Damstadt, Germany and attended the Gymnasium in his home town excelling at languages and drawing. He went on the University of Giessen planning to study architecture but after attending a lecture by Liebig of condenser fame, Kekule became fascinated with chemistry. He spent a year at home pondering a decision and decided to pursue an education in chemistry. Kekule studied in Paris under Dumas substitution theory and Gerhardt type theory then returned to Giessen to ... "

Abstract
This is a report on an experiment in chemistry on the law of definite proportions. It looks at the decomposition of potassium chlorate to potassium chloride with heating.
From the Paper
"The law of definite proportion states that different samples of a pure compound always contain the same elements in the same proportions by mass. For example, sodium chloride always contains sodium and chlorine by mass. In this experiment a sample of potassium chlorate was thermally decomposed to determine the mass percent of oxygen in the compound. A crucible containing g MnO catalyst was weighed and g KClO was added and the crucible and contents reweighed. A thermometer was placed in the crucible and..."
