juice are examples of strong acids having a pH of one and two while ammonia is an example of a base having a pH of 12. Milk and water are considered neutral because they are pretty even in the middle of the pH scale with a six and seven. (A&P I Lab Manual) pH is important to the body because thousands, maybe even millions of chemical reactions occur within the body. For you to live, all these reactions must be somewhat successful. For this to happen certain variables

At room temperature is a colorless gas with an odor similar to gasoline. It is an alkene used to manufacture rubber by addition polymerization. It has two C-C double bonds in its structure which allows the compound to form a wide variety of polymers including ABS. This compound is a toxic gas listed as a human carcinogen. Figure 2. Representation of 1.3-butadiene (mw: 54.09 g/mol) Styrene: A colorless to yellowish liquid that produce polystyrene by homopolymerization. Styrene is a derivative of

3. Results and discussion 3.1. Preparation conditions of molecularly imprinted polymer The preparation process of MIP is quite simple, but a number of factors which affect the polymerization and imprinted effect have to be taken to account. For the synthesis of the MIP, MAA was chosen as the functional monomer because, from the previous experience, this is the best functional monomer in order to establish selective hydrogen bonding interactions with the functional groups of bentazon. Another important

) The experiment may have had errors which allow the results to vary. The experiment was done over a short period of time and it takes a long time to fully experiment and research a topic which will allow the results to vary. A scientific lab has more accurate equipment which will allow the results to be more accurate unlike at home. By controlling the situation so precisely, results may be very

INTRODUCTION Earth is shield by the atmosphere where it is divided into several layer called ozone. Ozone is a molecule of three oxygen atom bound together and it is unstable and highly reactive molecule. Ozone is naturally in stratosphere when highly energetic solar radiation strikes oxygen molecule (O2) and cause the two oxygen atom to split apart in a process called Photolysis. A freed atom collide with another oxygen then it join up forming ozone, O3 . The formation of ozone is explained with

Enzymes are globular proteins folded into a complex 3-dimensional shape that contain a special surface region called the active site where specific substrate can bind structurally and chemically. They act as catalysts, meaning that they are substances which lower the activation energy required for a chemical reaction to occur and therefore increases the rate of the reaction. Activation Energy is the minimum energy barrier needed to be overcome before a reaction can occur by providing an alternative

Our control was the glucose solution which is a monosaccharide, and the experimental group was the sucralose solution which is a polysaccharide. To test our hypothesis, we first connected a carbon dioxide probe to a lab quest mini and connected it to out lap top that had logger pro software running. This probe needs to be connected for at least 5 minutes before any testing can be done. We then collected 5 ml of 1.5 mole sucralose and glucose in separate graduated cylinders

In this experiment I will be using yeast and six different types of berries, (acai berries, blackberries, blueberries, cranberries, strawberries, and raspberries). I am using yeast because yeasts are unicellular, eukaryotic microorganisms. Since yeast is the Fungi kingdom, there are approximately 1500 different species of yeast and many of them have different characteristics. Also yeasts reproduces about every 100 minutes and most do so asexually by mitosis. When compared to bacteria and some other

Introduction The independent research project will consist of multiple experiments that test the reaction rate of the catalase in the enzymes. The experiments will include tests on the following foods: nuts (peanuts and almonds), pineapple, chicken liver, and bananas (ripe and regular). There will be multiple tests on each food in order to gather accurate results. Research Louis Jacques Thénard first discovered hydrogen peroxide in 1818 and suggested that an unknown substance broke it down. Oscar

Interaction of +TIP protein EB1 with BubR1 for proper metaphase chromosome alignment In mitosis accurate segregation of chromosome requires proper attachment of microtubule to kinetochore. Although many proteins are found to be involved in this process, the actual mechanism by which microtubule attach to kinetochore and the stabilization of this interaction is not fully understood. EB1 is a microtubule + end binding protein, which is involved in kinetochore microtubule association and stabilization
