An important characteristic that hemichordates share with chordates is
1 Ventral tubular nerve cord
2 Pharynx with gill slits
3 Pharynx without gill slits
4 Absence of notochord
Explanation:
Hemichordata are soft-bodied, wormlike marine organisms which are often found in U shaped burrows on sandy or muddy sea bottoms and any animal that has a spinal cord is a chordate Both chordates, and hemichordates are deuterostomes with pharyngeal gill slits and most have a dorsal (and sometimeshollow) nerve cord
