From what I understand, I believe it is Thaliacea. This perspective comes from the fact that, unlike Appendicularia, Thaliacea possesses both a tail and a notochord during its adult phase.

Greetings! The question asks which among the listed groups consists of planktonic adults with a persistent tail and chordate into adulthood. The answer is B). Thaliacea. The rationale behind this choice lies in their nature as free-floating organisms throughout their entire lifespan, akin to bacteria. Hope this is helpful!

Consider an animal cell in which motor proteins in the kinetochores normally pull the chromosomes along the kinetochore microtub
enyata [1788]

The proper response is "yes, yes, no" or "B, B, A".

Clarification:

In this hypothetical situation, an inhibitor obstructs the function of motor proteins in the kinetochore while still allowing the kinetochore to stay attached to the spindle. The animal cells treated with this inhibitor can elongate during mitosis, leading to the separation of sister chromatids, but the chromosomes will remain still instead of moving to the poles of the cell. The only action the inhibitor affects is the motor protein function, which is responsible for the movement of chromosomes to the poles during cell mitosis.
