Caenorhabditis elegans provides a model for connecting genomics and development because (select all that apply):

Cell divisions are invariant allowing developmental tracking and genetic events that disrupt the normal fate.
The adults and eggs are transparent allowing visualization of developmental activities.
The normal cell lineage of every cell is known permitting identification of misplaced cells due to altered genetic events.
The adult forms are composed of millions of cells providing lots of opportunities to follow development.
