Due in great part to its characteristic of having a fixed number of cells in the adult, Caenorhabditis elegans has become an important model research organism in developmental biology. To which phylum does C. elegans belong?

Platyhelminthes

Annelida

Arthropoda

Nemertea

Nematoda

Phylum Nematoda

Explanation:

Caenorhabditis.elegans is a free-living transparent nematode about 1 mm in length.

C. elegans is a nematode—a member of the phylum Nematoda:

Nematoda.

The roundworms and threadworms, a phylum of smooth-skinned, unsegmented worms with a long cylindrical body shape tapered at the ends; includes free-living and parasitic forms both aquatic and terrestrial.

C. elegans is a non-hazardous, non-infectious, non-pathogenic, non-parasitic organism.  It is small, growing to about 1 mm in length, and lives in the soil—especially rotting vegetation—in many parts of the world, where it survives by feeding on microbes such as bacteria. It is of no economic importance to man.

the  different  of  these  two  are  that  they  differently  handle  their  team.

an  expressive  leader  focuses  on  the  task  at  hand  and  make  sures  that  their  goal  is  achieved.  they  accurately  finish  the  task.  an  instrumental  leader  on  the  other  hand  works  on  the  unity  of  the  group,  they  care  more  about  their  employees.  all  the  while  creating  a  good  environment.
