The next check on this week's work. It covers a different skill from the last one, so this is a fresh check rather than a retake. Enter your Student ID and submit.

1. 1. Scientists use model organisms like C. elegans mainly because they:

   AAre large enough to dissect by handBShare basic biology and grow quicklyCGive results that apply directly to patientsDHave the same organ systems as humans

2. 2. A team's plan for a C. elegans assay leaves the E. coli lawn off the agar plates. The plan fails because that lawn is what:

   ABlocks other microbes from settling on the plateBShows whether the plate was contaminated before useCFeeds the worms for the whole length of the studyDKeeps the agar from drying out during the study
