Place 10 drops of Copper (II) sulfate‚ Cu SO4 into well A5 of the 24-well plate. 6. Take the metal solids from your LabPaq; there should be one piece each of magnesium‚ zinc‚ and iron plus two pieces of lead. Note: Magnesium and lead oxidize very easily and an almost invisible oxidation layer may coat the metal. To insure good reactions you should scrape the surface

Background examination for the Dominant Thumb Experiment: • Upon reading the literature that the researcher found by googling‚ "Thumb Dominance‚" they discovered that almost every human being has a dominant thumb whether it be the right thumb or the left thumb on top after naturally clasping their hands together. However‚ if the individual tries to force their clasped hands to let the other thumb become dominant it ’s most often described as feeling awkward or abnormal. In 1999‚ a scientist by the

highest number of cells in mitosis we did an experiment where we found out cells that are closer to the root tip are more likely to be doing mitosis than the cells that are further away from the root tip. Through the experiment‚ we looked at the zone of cell division‚ which is

The role of mitosis relates directly to the development of Kaposi Sarcoma. In order for cancer cells to begin to form‚ they must have something go wrong inside of the cell or something that makes things work incorrectly. In the article “Do we know what causes Kaposi Sarcoma?” on cancer.org‚ it states “In KS‚ the cells that line blood and lymphatic vessels (called endothelial cells) are infected with KSHV. The virus brings genes into the cells that can cause the cells to divide too much and to live
