Themes in U.S. & World History; Geographic and Environmental Factors An example of physical geographic factors that contributed to the development and expansion of the United States are the Appalachian Mountains and the discovery of the Cumberland Gap. The second geographical factor that significantly contributed to the development and expansion of the United States is the major rivers of the Midwest regions such as‚ “The Mississippi‚ Ohio‚ Missouri‚ Illinois‚ and other rivers knit together

Enzyme Activators and Inhibitors Lucia House AP Biology‚ Block 4 Mr. Trice October 18‚ 2012 Introduction: Metabolism is the totality of all of an organism’s chemical reactions. Chemical reactions occur due to enzymes‚ a substance which acts as a catalyst in driving chemical reactions in order to produce a desired product (Campbell and Reece‚ 2002). A catalyst is usually a protein; however‚ some catalytic molecules counter this generalization. A discovery made in the early nineteen- nineties

Research Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. In the

Potential effects of different factors on development I am going to write about the following factors and how they may affect the development of an individual. · Rubella (Biological) · Cystic fibrosis (Genetic) · Smoking (Lifestyle) · Poor Housing (environmental) · Poverty (Socio-economic) Rubella & CRS Rubella is an infection also known as German measles. It is most common amongst children but may also affect adults. It is passed on through the tiny droplets in the air. If a pregnant woman

To investigate the effect of different caffeine concentration on the heartbeat rate of Daphnia at room temperature. Introduction: Caffeine is found‚ and produced in many plant species to function as a natural pesticide‚ and as an inhibitor of seed germination of other nearby coffee seedlings to give it a better chance of survival. Caffeine is able to paralyze and kill certain insects upon feeding on the plants that produce caffeine. Coffee‚ tea and cocoa are common caffeine-containing

pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase. When a serial dilution was

The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

Environmental Factors Paper This paper will discuss the five environmental factors that influence global and domestic marketing decisions that organizations must make. The five environmental factors are social‚ economic‚ technological‚ competitive‚ and regulatory. The social forces of the environment as defined in Marketing‚ include the demographic characteristics of the population and its values (Kerin & Berkowitz‚ Hartley & Rudelius‚ 2006‚ p. 74). This includes gender differences‚ buying
