Question

Hemichordates do not resemble chordates with respect to

• A. Notochord
• B. Absence of dorsal tubular nerve
• C. Presence of pharyngeal gill slits
• D. None of the above

Answer 1

The correct option is A Notochord

Hemichordata are any of the group of worm-like marine invertebrates closely related to the chordates. This name was first proposed because the buccal diverticulum, which is a tubular outgrowth from the mouth cavity forward into the proboscis, or snout, resembles a rudimentary notochord (but still unclear about notochord's presence).
