Brooke Strowd AP Biology Ms. Butler 28 January 2013 I. Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit

The Causes of the Rising Divorce Rate There were once the moments that take their breath away‚ leaving their hearts pounding and throat thickening; there were once the ones whose name they secretly write down on their diaries and whose footsteps they can carefully distinguish from others’.

1.1 Explain the sequence and rate of each aspect of development from birth to 19 years All infants‚ children and young people follow a basic pattern in development. The rate they develop will vary from child to child. This is because all children are individuals‚ however knowing what to expect and roughly what age to expect it (milestones) can help us recognize development issues (early recognition is essential). Development is broken down into five section although they are separate‚ they all interconnect

different amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more mass than others. Solution A had 0.6 molarity

What is the rule of 72? Well… here’s the equation: Years to double = 72 / Interest rate DO NOT reread this equation. The rule of 72 is a hard rule to explain. I will do my best to try to explain it. The answer to ‘rule of 72’ gives us a number of years. This number of years tells us how long it takes to double our money. Let’s say you have 100 dollar. The ‘rule of 72’ helps us figure out how long it will take to have 200 dollars. Scenario 1: You have invested your 100 dollars in a 3%

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation

Heart Rate Anticipatory Response: Anticipatory heart rate is the rate that the heart reaches before the start of exercise. Your heart rate usually picks up as a result of the anticipatory heart-rate response‚ this happens before exercise. When thinking about exercising before actually starting‚ the nerves that release the chemicals that adjust your heart rate increase the heart rate. The body expects exercise and therefore prepares for the activity‚ increasing the amount of oxygen being delivered
