Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

peroxidase. The three conditions tested were the effect of peroxidase concentration on the rate of the experiment‚ the effect of pH of the rate of peroxidase activity‚ and the effect of temperature on the rate of peroxidase activity. During the lab‚ the lab group tested 7 test tubes‚ including 1 blank‚ with different amounts of pH 5 buffer‚ H2O2‚ Peroxidase‚ and Guaiacol. After the certain amount of mL per substance was mixed‚ the absorbance readings for the effect of peroxidase concentration were

Introduction The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Purpose The objectives of the lab were to help give us a better

Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently

Social African slavery in the American colonies first began in the 1670’s and 1680’s‚ particularly in the Chesapeake region. However‚ it wasn’t until the 1700’s that slavery became a full blown business.
