The Identification of Bacillus Badius [pic] Hannah Melanchuk Dr. Robert Suran May 1 2013 Microbiology Abstract Over a three week time span I was able to successfully identify an unknown microorganism by combining the results of several tests. The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart‚ I proceeded to inoculate a Starch plate. In week 2‚ I

To demonstrate dialysis tubing we used water‚ starch and iodine. When starch and iodine react together they form a dark brown color.

Pathophysiology. Thyroid hormones assume a vital role in the normal functioning of the body. Insufficiency in secretion from their source to respond to body needs in the body risks infection of hypothyroidism. They are secreted by the thyroid glands which are located in a close-range to the trachea between the cricoid cartilage and suprasternal notch where they possess two joined lobes by an isthmus. In addition‚ the thyroid hormones are inconclusive of triodothyronine (T3) and thyroxine (T4) that

In this experiment‚ the following type of reaction is considered: aA + bB → cC + dD (1) The rate law is: Rate = k[A]x[B]y (2) The reaction that occurs between the iodine ion and bromate ion will be studied‚ which is as follows: 6I-(aq) + BrO3-(aq) + 6H+(aq) > 3I2(aq) + Br-(aq) + 3H2O(1) (3) Then‚ the rate of the reaction is concluded to be: Rate =

The trace mineral iodine found primarily in seafood‚ seaweed‚ plants grown in iodine-rich soil and iodized salt is essential for the production of thyroid hormones. Before the 1920s‚ it wasn’t unusual for people to develop hypothyroidism because they consumed too little of this mineral. But the addition of iodine to table salt has virtually eliminated this problem in the United States. In other parts of the world‚ however‚ as many as 200 million people may have iodine deficiencies.

First we put 500 ml of amylase from 0.2% solution (provided by Michael Bunch) into an experimental tube. We then put 3 drops of Iodine into a test plate (the color is brown). While

4 elements that had not been discovered yet and it contained the atomic mass of the elements. DISADVANTAGES: * When Dmitri put the elements in order of atomic mass‚ he had trouble getting iodine because iodine was similar properties to chlorine and bromine. But iodine had a low atomic mass. So iodine could not be in his rows. This caused Dmitri to break his own rule; he made for the periodic table.
