ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

salt solution is 6.3grams and the 15% salt solution is 6.8 grams. My hypothesis was that the carrot would shrink and be very small and gooey‚ but it was wrong. The controlled variable in this lab is the carrot and time‚ the manipulated variable is the salt solution‚ and the resulting variable in this lab is what happens to the carrot. Materials and Methods: . Salt solution ( 0-15%) . 4 Carrot pieces from same Carrot( Cut carrot in half if needed) . 4 Beakers . Water . Triple beam balance

Benjamin Kleveland 502 October 26‚ 2014 Lab 7 Report Lights Distance and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical

Labs and Diagnostics Colonoscopy This test allows direct visualization of the small bowel‚ rectum‚ and colon. It is recommended for patients who have experienced fecal occult blood or obvious blood in the stool. It is also recommended for patients who have experienced a change in bowel habits or are experiencing abdominal pain. In patients who have had colorectal cancer‚ polyposis‚ or inflammatory bowel disease it is used to observe for continued progression of their condition. During the procedure

couple of key things about lab safety and procedure during this experiment. While working with the hot plates‚ I learned to pay a lot of attention to whether or not the hot plate was plugged in or turned on‚ as well as whether or not the wax was getting too hot. Measuring each substance into the cup was an important experience because it taught me to be deliberate and careful when measuring so as to not waste materials‚ making sure we did not have to start over. While this lab is a good starting point

Lab: Investigating Soils Observations/Data Record the observations and/or data you collected here. Describe the color‚ feel‚ and appearance of each soil sample. Sample 1: Play ground sand: khaki colored‚ feels rough‚ has more sand than rocks. Sample 2: Potting soil: black/brown-ish colored‚ feels some what soft‚ has little pieces of bark (woody stem‚ branches‚ and roots of plants.) Sample 3: Backyard soil: Orange-red‚ feels lumpy‚ muddy look alike. What is the texture of each soil sample
