Answer:
The phylum Hemichordata is the one that could form an evolutionary connection between the chordates and non-chordates.
Explanation:
To the phylum Hemichordata belongs a genus that scientists believe could explain how the chordates could evolve from the non-chordates. This genus is Balanoglossus, of the class Enteropneusta.
Balanoglossus is similar to a worm, whose habitat is the seabed, and like other hemicordates it has a stomach, a structure that forms part of its digestive system and fulfills the functions of a spine.

Answer:
It would block the generation of action potential in the motor neurons
Explanation:
Tetrodotoxin (TTX) is a toxic compound found in the Pufferfish which could affect the neuronal signalling in the humans.
The tetrodotoxin binds to the sodium channels present in the motor neurons in the soma region of the neuron where the binding of the tetrodotoxin to the sodium channels inhibits the inward flow of the sodium ions. The reduction in the influx of sodium ions does not change the depolarization of the cell membrane and hence action potential is not generated in the motor neuron.
Thus, It would block the generation of the action potential in the motor neurons is the correct answer.
