support@essaywritingexpert.orgThe biology labs do require some completion of experiments. Some of the experiments call for the use of multi colored beads, however, simple math can be used in place of the beads. If you have any question please review the lab before submitting a bid. It is large but relatively simple. Also, one of the labs require that it is recorded and the video submitted. I already completed the recording all that remains is the answers to the questions.
