Why do adult urochordates (tunicates) lack notochords, even though larval urochordates have them? Larvae use notochords to _____
kirza4 [7]

Answer: Option A

Explanation:

A tunicate is marine invertebrate animal  which is a part of chordates. They have notochords and dorsal nerve chord. The subphylum of the organism is called as Urochordata.

The adult urochordates lack notochord but the larval stage of the urochordates have notochord. This is because it helps in swimming of the organism which is required only at the larval stage.

The adult stage of the tunicates is sessile and they do not swim so they do not require notochord.
