Simpson ’s Diversity Index is a measure of diversity. In ecology‚ it is often used to quantify the biodiversity of a habitat. It takes into account the number of species present‚ as well as the abundance of each species.( Simpsons Diversity Index‚ August 2012. http://www.countrysideinfo.co.uk/simpsons.htm )

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

Ecology Of Crime There are many patterns in the crime rate that seem to be linked to temporal and ecological factors. Crimes usually happen more often‚ and‚ or more less according to the day‚ season‚ climate‚ temperature‚ population density‚ and region. For example‚ a person is more likely to be assaulted at midnight when the temperature exceeds 90 degrees than when to temperature is 10 degrees below zero. Therefore‚ a criminal is more likely to commit a crime when the time of day‚ season‚ and

Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

BUSINESS AND ECOLOGY Businesses damage the environment when they take natural resources from the Earth and dispose of waste. All of this is done within the natural environment‚ a kind of ecological system or “ecosystem.” THE DIMENSION OF ECOLOGICAL PROBLEM Ecological Problems: These are the some of the environmental issues we face today: 1. Non-stop illegal mining. 2. Air pollution contaminates the air‚ despoils vegetation and crops‚ corrodes construction materials‚ and threatens our lives
