Please complete a pre-lab analysis report according to the guidelines I uploaded. The first three are the files needed for this lab, and the next two are the pre-lab sample and pre-lab requirements. The last one is the last pre-lab I wrote. Based on these files, please browse and complete the pre-lab carefully. More importantly, if you have something you uncertain or do not understand, please consult with me in time. In this way, the quality of the final work can be better guaranteed. You can call me Jason. Glad to cooperate with you.
