Mr. Clark Honors Bio Period 3 10-19-13 Eukaryotic Cell vs. Prokaryotic Cell Eukaryotic cells do have a nucleus but Prokaryotic cells do not. Prokaryotic cells usually only have one chromosomes when Eukaryotic cell have more than one. Eukaryotic cells have mitochondria but Prokaryotic cells do not. Prokaryotic cells are usually unicellular and Eukaryotic cells are usually multicellular. Also Eukaryotic cells are larger than Prokaryotic cells. Both Eukaryotic and Prokaryotic cell have vacuoles

Biology- Change in pH Aim: To investigate the affect that change in pH levels has on a particular enzyme‚ in this case amylase. Hypothesis: In this investigation I expect as the pH reaches the optimum level‚ the rate of reaction will be fastest‚ compared to other pH levels. It is also suspected that after the enzyme has reached optimum level the enzyme activity will decrease. Through further study of the optimum level of amylase I found that the enzyme usually has an optima pH of 8. It is known
