Mitosis Under Microscope Lab Report A. The purpose of the investigation is to determine the time an onion cell spends in each part of the cell cycle. B. The significance of this investigation is to help us understand and know how long cells are undergoing mitosis. My personal interest is to know the phases of mitosis in cells in order to someday help find cures for cancer. C. The cell cycle is a chronological set of events‚ culminating in cell growth and division into two daughter cells. Some

Copper Cycle Summary During the copper cycle lab‚ my partners and I performed a series of reactions on copper powder and observed the changes it underwent. For the first step‚ we mixed nitric acid and copper powder‚ and noticed that a yellowish brown gas emerged‚ along with effervescence. The red solid disappeared and became a blue liquid. We know that we produced copper nitrate‚ nitrate gas‚ and water because the only two blue solutions in “A New Language” are copper sulfate and copper nitrate
