An important characteristic that Hemichordates share with Chordates is:
- AVentral tubular nerve cord
- BPharynx with gill slits
- CPharynx without gill slits
- DAbsence of notochord
Solution & Step-by-step Explanation
Both Hemichordates and Chordates possess pharyngeal gill slits. Chordates have a dorsal tubular nerve cord and a notochord, whereas Hemichordates have a ventral nerve cord and a structure called the stomochord (not a true notochord).
