Figure 1 shows the average amount of absorbance for each tube‚ containing different levels of pH. Tube 2 had an acidic pH level‚ Tube 3 had a neutral pH level‚ and Tube 4 had a basic pH level. It is indicated that the absorbance rates were the highest for the neutral pH level‚ with a final absorbance rate of 0.166. This was followed by a basic pH (0.106). The acidic pH level had the least amount of absorbance with a final absorbance rate of 0.069. This reinforces the idea that the ALP enzyme worked

In Graph 1‚ each line of color represents a different level of pH added to the solution. When pH 9 was added‚ it produced the highest rate of reaction (the most oxygen was produced)‚ whereas when the more acidic pH 5 was added‚ the rate of reaction was much slower‚ and less efficient. The higher the oxygen evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal

1: EQ1 – What economic reasons caused Europeans to colonize North America? There were four key European countries that colonized North America. Read about these countries below and then contrast their economic reasons for colonizing on a graphic organizer. Several European countries followed the trip made by Columbus in search of new trade routes to Asia. They ended up colonizing North America for different economic reasons. Spain colonized America because they were searching for gold and silver

to determine the molarity of NaOH‚ we rinsed a burette with about 5ml of water and another 5ml of NaOH to prepare it for the experiment. We then measured exactly 25ml of the prepared KHP from the previous part into a 250ml Erlenmeyer flask and added 2 drops of the indicator‚ phenolphthalein. Next we filled the burette with the approximately 0.1 M NaOH so that our initial volume will be 0.0mls. We then started our titration by carefully pouring a little amount of the base into the prepared 25ml of
