The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

DNA almost immediately transformed the American Criminal Justice System. Law Enforcement‚ District Attorneys‚ Defense Attorneys‚ Criminal Court and Family Court all work with DNA on a daily basis. DNA that can be utilized in a criminal investigation may be collected from a crime scene in many different forms: skin tissue‚ hair‚ blood‚ semen‚ saliva‚ vaginal fluid‚ anything that may be collected from a human that may contain cells can be utilized and tested for DNA. DNA testing is the most

certain environmental factors affect the enzyme activity rate. For the first experiment‚ where we tested the increase in concentration of enzyme with the substrate‚ we found that higher concentration of enzyme increases the rate of reaction of the enzyme. This is because more enzyme molecules are present‚ which allow more substrate molecules to get into the active sites of the enzyme (Sattler W& Esterbauer H). When calculating the absorbance of different enzyme concentration‚ it was noticeable that

Groyne Investigation FINAL Report‚ Alice Cearns ABSTRACT The purpose of the investigation is to analyse the effect a groyne has on a beach’s formation and sand deposition‚ and the seasonal impact the ocean has on its shoreline. South Cottesloe beach contains native plants‚ from berry saltbushes to red-eyed wattles; it has accumulated sea wrack and rocky surfaces especially south of the groyne‚ and sand dunes running down to the swash zone. With fences running parallel to the water line‚ this

A detective is a police officer‚ whose duty is to detect criminals‚ by in-depth investigation of cases. When attempting to solve a crime‚ detectives conduct a criminal investigation that seeks all the facts about a crime to help determine the truth: what happened and who is responsible. This involves making a preliminary and final investigation. A detective’s task is to gather‚ organize‚ and use information about social behavior. To effectively complete that task a detective should possess
