One of his written piece has the same name as its biggest event‚ “The Highest Tide” – the story of one summer that changes Miles O’Malley’s perspective of life. In chapter 29‚ the biggest event begins to happen here‚ Miles and Phelps go to downtown to see if the tide is really rising. He gives an indifferent description about this event which shows that he does not astonish with it because he

Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the

Lab Section LA: 06/20/2012 Introduction pH is the measurement of the concentration of hydrogen ions in a certain solution. Solutions or substances that have a higher concentration of hydrogen ions are considered acidic on the pH scale. Therefore‚ a solution with low concentration of hydrogen ions is basic on the pH scale. The pH scale is a universal means

effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we measured was 3.0‚ which was collected
