We calibrated three different molarities of copper (II) nitrate. We tested for the %Transmittance of 1M, 0. 1M, and 0. 01M and plotted the data collected on a calibration curve based on concentration and absorbance. We used nitric acid to dissolve a penny to produce …
* The origin of eukaryotes is important to understand the origin of modern complex cells. There are three main separate theories that hypothesize the origins: the three-domain system, eocyte theory, and endosymbiosis. Each one have there own merits and evidence supporting. These theories suggest the …
