ab: Observing a Chemical Reaction Name: Deja Eason Period: 5th Period Partners: Melingh Patterson‚ Tori Millens Date Performed: 9/2/11 Teacher: Mrs. Medina Abstract: This experiment was all about observing a chemical reaction. During the experiment‚ we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride‚ Aluminum foil‚ and Distilled water. Before the Aluminum

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for

dentifying the classes of Biomolecules The Introduction A Biomolecule is any molecule that is in the human body. There are four major biomolecules‚ they are Carbohydrates‚ Lipids‚ Proteins‚ and Nucleic Acids and they all have different functions and characteristics to classify an organism. Carbohydrates are the most important source of energy for your body‚ this is mainly sugar. Lipids are molecules that contain hydrocarbons and make up the structure and function of living cells. Nucleic acids

When you are close to‚ or are handling‚ blood‚ body fluid‚ body tissues‚ mucous membranes‚ or areas of open skin‚ you must use personal protective equipment‚ depending on the anticipated exposure‚ such as gloves‚ mask and goggles‚ apron‚ gown‚ and shoe covers. Airborne precautions may be needed for germs that are so small they can float in the air and travel long distances. Airborne precautions help keep staff‚ visitors‚ and other patients from breathing in these germs
