of distilled water will be measured using a graduated cylinder. The 50g of catalase and the 50ml of distilled water will be put into a blender and blended until liquefied. The catalase solution will then be introduced to a Buchner funnel filtration system to separate the catalase extract from any solid particles left over from the blending process. This step will be repeated until all of the catalases have been blended and filtered. Next‚ 5 ml of hydrogen peroxide will be measured out using a graduated

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

Once broken‚ the "enzyme" must drop the toothpicks directly back into the same pile of unbroken toothpicks. 6. Choose one person to record the amount of broken toothpicks‚ the time (10 second intervals of 120)‚ and a person to count the toothpicks during the reactions. 7. Repeat steps 1-6 except the "enzyme’s" index

Researchers have debated what the most effective method is for preventing catheter acquired urinary tract infections (CAUTI). Many researchers compared cleaning the meatal surface around the catheter using soap and water with cleaning the meatal surface with antiseptic solutions. The research studies discuss when an indwelling urinary catheter is in place which of these two methods is most successful for preventing CAUTI and which of the two is not recommended. The end goal of this study is to determine

Experiment 42: Ferrocene Preparation Introduction: The purpose of the lab is to prepare ferrocene from ferrous chloride and cyclopentadiene. Ferrocene‚ an organometallic‚ is a combination of two cyclopentadienide ions with a ferrous cation‚ such that the six pi electrons binds every carbon equally to the metal forming a sandwich type structure. Ferrocene has the properties of both an activated benzene (undergoes electrophilic substitution reactions) and a ferrous ion (oxidation reaction). Glyme

Being able to control and maintain appropriate amounts of glucose in the bloodstream is vital to the functioning of many systems within the body. Without adequate amounts of glucose‚ skeletal muscles cannot function properly‚ vision becomes disturbed‚ headaches and moodiness can occur‚ and the brain has a difficult time functioning properly. On the other hand‚ excessive amounts of glucose within the bloodstream can cause nerve damage‚ blindness‚ cardiovascular issues in the lower extremities‚ and
