Straighterline A&P lab question?

Has anyone taken A&P through Straighterline that can answer this question? I am working through A&P2 lab and just started on the first one. They have 5 parts listed to this lab with a couple experiments along with a dissection, but it looks like the only part that gets turned in is a photograph of the dissection. Um, I hope this doesn't make me sound inherently lazy, but if I do not have to turn in these experiments I sure as heck am not spending my time doing them. I am trying to get this done as quickly as possible and do not have time to spend on assignments that are not even being turned in let alone graded. Am I missing something? Did others who have taken this just skip the lab parts that were not being collected?
