Answer:
1. Chordata
2. Annelida
3. Arthropoda
4. arthropods
5. totipotent cells
6. potentially mobile
7. radially symmetrical adults
Explanation:
Chordata includes organisms with a dorsal nerve cord, notochord and pharyngeal slits.
Annelida is composed of segmented worms, bilaterally symmetrical and coelomate.
Arthropoda is the largest animal phylum which is composed of organisms that possess a segmented body, exoskeleton and paired appendages.
Totipotent cells are cells capable of dividing in order to produce a completely differentiated organism (e.g., zygotic cells).
Animals are organisms generally motile capable of moving in their environment.
Starfish are star-shaped invertebrates with five or more arms, where arms radiate from the central disk.
