ankoles [38]

Answer:

Central and Peripheral

The nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord.

On the other hand the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body.

The below diagram provides a schematic view of the role of each sub-division  of the Nervous System.

Unlike DNA, RNA
Lisa [10]
<span>The answer is D. pairs uracil with adenosine instead of thymine. Through the process of elimination, both DNA and RNA contain nitrogenous bases.

Thus, the correct choice is D. because RNA pairs uracil with adenosine instead of thymine like DNA.</span>
