Dear Pulitzer Judging Board‚ The book‚ The Color Purple by Alice Walker was superior. This book should have received the Pulitzer Prize because it contains some of the best elements‚ in which this book very unique.

lab shows the use of salivary amylase with strong and weak starch mixtures to break down complex carbohydrates into simpler sugars. This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It is found that benedict’s solution‚ when heated makes a yellow-orange colour to indicate the simple sugars. Iodine is the

the lab experiment six different test were conducted. Each test consists of chemicals to be tested using 3 to 10 drops of the additive in order to observe a change. With any experiment you compose a hypothesis; where you make an educated guess. The hypothesis will primarily be‚ which base chemical will produce the greatest change based on the additive. Experiment 6.1 (Starch) when adding the three drops of Iodine to each tube observe the color change. When performing this test the chemical with the
