Investigating a Crime Scene Denise Swank Bryant & Stratton College Criminal Justice: Research Paper Mr. Frank Chmarak December 2011 Investigating a Crime Scene On TV shows like "CSI‚" viewers get to watch as investigators find and collect evidence at the scene of a crime‚ making blood appear as if by magic and swabbing every mouth in the vicinity. Many of us believe we have a pretty good grip on the process‚ and rumor has it criminals are getting a jump on the good guys by using the

When converted to pepsin‚ the enzyme is used to break down large or undigested protein they has been absorbed by the small intestine. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7)‚ and pepsin is no longer effective.

The effects of human activity on ecosystems and biodiversity Agricultural Practice Biodiversity is a measure of the diversity among organisms in different ecosystems. "Diversity" in this definition includes diversity within a species and among species‚ and among ecosystems.’ Monoculture is when a farmer produces or grows one single crop over a wide area. The advantages to the farmer of monoculture are‚ “the reduced plant competition for nutrients‚ space and solar radiation‚ control of unprofitable

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

FUNCTIONS OF ENZYMES Enzymes are extremely important to the human body and its ability to function. An enzyme itself is a protein made by the body’s cells to act as catalyst‚ speeding up chemical reactions in the cell. It does this by taking the reactants‚ or the elements or compounds that enter into the chemical reaction‚ in this situation referred to as substrates‚ and breaking apart their bonds so that new ones can form. The three types of enzymes are digestive enzymes‚ food enzymes‚ and metabolic

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get
