Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held

Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential

Introduction This report will investigate the six essential nutrients required in our diet. The report will provide the function of each nutrient and explore why they are vital for the body. Carbohydrates Carbohydrates are the most important nutrient for the body as it is the largest possible source of energy. Carbohydrate supplies the body with energy‚ which allows the brain to function more effectively and allows organs to operate sufficiently. When the body has energy this allows each

ligation mixture)‚ the presence of the white colonies shows the successful transformation of the ligation mixture to the JM101 with ampicillin resistant ability. As the lacZ’ gene was disrupted in the ligation mixture plasmid‚ only non-functional lacZ product can be formed and results in white colony only. In plate 3‚ there is only white colonies can be observed. It shows the successful transformation of pUC18 to JM101 with ampicillin resistant ability. The absence of the x-gal and IPTG inducer leads

Variables: Control- The group with zero salt added. Dependent- Dissolved oxygen reading. Independent- The salt concentration in the water. Introduction: On the surface waters of lakes and oceans‚ plants are mainly unicellular algae‚ and most consumers are microscopic crustaceans and protozoans. Both the producers and consumers

ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the
