2011 Plants and Nitrogen Lab Report Introduction: Plants need ammonia‚ a combination of nitrogen and hydrogen‚ or nitrate‚ a form of inorganic nitrogen to grow. Most nitrogen is found in the atmosphere. However‚ plants and animals cannot directly absorb the nitrogen found in the atmosphere. Instead nitrogen gas is captured from the air by species of bacteria that lie in the water‚ soil‚ or grow on the roots of some plants. These bacteria convert the nitrogen into a form usable by plants. The

2 Should Wild Animals Be Pets At Home? Many people have questioned whether they would ever consider to buy a wildlife animal as a pet. Although owning a wildlife animal would seem out of this world‚ it’s not worth risking the lives of these poor animals who are meant to be out in the wild. Wildlife animals are not as domesticated as dogs. They have wildlife instincts even when they are in captivity; this is very dangerous for us humans who would own one of these exotic animals. By owning a wildlife

The Effect of pH on the Rate of Enzyme Catalysis of Catalase Objectives: The objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme. More specifically‚ the objective was to perform an experiment in order to test the effect of pH on the function of the enzyme catalase. Introduction: Enzymes are proteins that act as catalysts for reactions. This simply means that enzymes lower the activation energy required

My Winter Break Phil Fatigato 1-12-11 My winter break went by very fast. I was disappointed to come back to school already. But I did enjoy my break! I did many fun things over break. I hung out with friends‚ went downtown and partied for New Years Eve‚ and snowboarded at Cascade Mountains and Alpine with friends. First thing I did over break was hang out with friends. We went Christmas shopping together. We also went to the movies‚ out to lunch‚ and drove around. It was fun to

Abstract Enzyme catalysis was observed in order to analyze how changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly‚ decreases‚ and levels off or completely stops‚ and can be further affected by environmental factors

the president came on T.V. and announced that there were no more rules‚ if it became legal to do whatever you want‚ would you break those rules? What if the general opinion was that you should follow the old rule? Would you still break those rules? Opinions can make all the difference when it comes to how well a society runs. I feel that rules don’t determine a society’s actions and lifestyle‚ opinions do. “‘—and then‚ the beast might try to come in. You remember how he crawled—’ The semicircle

Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The

The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices is hydrogen peroxide and phenol oxalate ester. The hydrogen peroxide is kept in a thin‚ small glass vial in the middle of the stick‚ and the second chemical phenol oxalate ester is in the main body of the light stick. Bending the light stick in the middle causes the small glass vial of hydrogen
