Question

Why do adult urochordates (tunicates) lacknotochords, even though larval urochordates have them? Larvae use notochords to induce tissuedifferentiation; in adults, tissue is already differentiated. Larvae use notochords to aid in swimming;adults are sessile and thus no longer need notochords. Larvae use notochords to organize their nervoussystems; adults' nervous systems are fully developed and do notchange. Larvae use notochords to stiffen their bodies;in adults, the notochord is replaced by a column of bone.

Explanation / Answer

I said C but I meant B:Larvae use notochords to aid inswimming; adults are sessile and thus no longer neednotochords.
If you'd read my post I did explain the answer though :( I'msorry for all the trouble
