Most of the endoplasmic reticulum is concentrated in the cell body region of a neuron.
Endoplasmic reticulum (ER) is a membrane-enclosed cell organelle which is present all over the cytoplasm of every eukaryotic cell.
Electron microscope studies reveal that endoplasmic reticulum is present throughout the cytoplasm in neurons including the cell body, dendrites as well as axon.
However, it also shows that ER is largely concentrated in the cell body of a neuron.
A neuron or nerve cell is made up of three important regions viz. cell body, dendrites as well as axon. The cell body consists of cytoplasm with distinctive cell organelles as well as definite granular bodies which are known as Nissl's granules.

Answer:
Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.
Ethyl alcohol and carbon dioxide are the end products of Alcoholic fermentation.<span />
Animals that only survived in certain climates have fossils that are in the opposite of the range of temperatures needed for their survival. Also The plants have fossils in two different climate regions that indicates that the region was once in a different location. Such as the fossil of a plant called glossopteris. And deep scratches in rock found in South Africa that are usually created by the movement of glaciers.
Answer:
B. carbon only bonds with other carbon atoms
Explanation:
A carbon bonds well with itself and make a stable compound because it only bonds with other carbon atoms.
