Introduction: The technique used in this experiment is recrystallization. Recrystallization is an often-used method for purifying solids. Recrystallization works by taking advantage of the different solubility properties of compounds‚ and allows impurities to be removed from crude solids. Performing a recrystallization is usually a straightforward task. First‚ you add a small amount of solvent to the impure compound in a flask‚ and heat the contents until all the material has dissolved. Then‚ you

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

comparatively long time in the mitotic phase‚ whereas those cells comprising slow-growing tissues would spend most of their lives in interphase. Non-dividing cells remain in interphase and never enter the mitotic phase. (Lab Manual 64) Interphase is the synthesis of biological molecules including DNA and duplicated DNA with associated proteins. These comprise the chromatin that begin to condense toward the end of this phase‚ but are not yet visible. The nucleoplasm has a uniform grainy appearance.

The Determination of the Concentration of Hard Water Ions by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts

For this lab‚ the expected outcomes are that when the heart rate and blood pressure are measured‚ both will increase when the heart has to pump against gravity‚ after exercise the heart rate will increase then return to normal‚ and as the subject inhales‚ it will be lower than when they exhale. Methods For this lab report‚ the laboratory manual (2009) was used for all labs. While completing lab five‚ electrodes were hooked up to the subject. After calibration for this lab‚
