-Interneurons are only located in CNS & connect between motor and sensory neurons. They exist only in the central nervous system (brain and spinal cord). They relay messages from sensory neurons to motor neurons and also bring message from various sources, organizing and integrating information.
-Motor neurons (efferent neurons) transmit neural messages from the brain to various areas of the body including muscles, internal organs and glands. They enable bodily movements, internal organs to be activated and glandular secretions to occur. They also Receive and act on messages received from interneurons.

Answer: The correct answer is -
Eubacteria and Archaebacteria.
As per the information in the question, scientist finds a new life form and determines that it contains no nuclei.
This indicates that the new life form is a prokaryote.
Prokaryotes are the organisms that are devoid of nucleus and do not contain any membrane bound subcellular compartments (cell organelles).
Archaebacteria (primitive forms of bacteria) and Eubacteria are the two groups of prokaryotes.
Thus, Eubacteria and Archaebacteria is the right answer.
