Okay well the signal or the movement coming through the neuron(and its axon) is about the ions. The ion is a charged like particle, such as Na+ (If you remember that). Na+ is a sodium ion. So most of those ions I was talking about before just simply flow in or out of the cell. I hope this helps! <3
The spinal cord contains ascending and descending nerve fibres that send information between the CNS and the periphery. This illustrates the conduction function of the spinal cord.
The bony components of the vertebral column serve to shield the spinal cord, which is a component of the central nervous system (CNS) and which spans from the head to the tail of the body. It is protected by the three membranes that make up the central nervous system, which are the pia mater, the arachnoid, and the dura mater.
The spinal cord contains the descending and ascending nerve fibres. The spinal cord is an important component of both the central nervous system and the peripheral nervous system. It is connected to the rest of the nervous system by a network of 31 pairs of spinal nerves, which are responsible for carrying sensory information. These nerves go up the spinal cord or through the medulla oblongata to reach the subcortical nuclei, where they form synaptic connections.

The cell wall gives cells shape, enables plant growth, prevents bursting from water pressure, keeps out water and pathogens, stores carbohydrates and sends signals to cells. The flexible cell wall surrounds plant cell membranes.
Plant cell walls perform many functions. Their main task is to support proper plant growth. This is accomplished by the cell wall creating a skeleton-like frame that enables plants to grow vertically and develop a rigid stem. Cell walls vary considerably in thickness and organization, which accounts for the wide range of plant shapes and sizes on the planet. They consist of two layers ‰ÛÓ a primary cell wall, which supports the cell as it matures, and a rigid secondary cell wall that appears after the primary wall stops growing. The primary cell wall is thinner and more flexible than the secondary wall. Internally, the primary and secondary walls have a similar physical composition. Over the course of a plant's life, they perform complementary functions to keep the plant healthy and vibrant.
Answer:
A.) used for energy in animals and plants
Explanation:
(B) is a characteristic of a nucleic acid. DNA, an example of one, contains genetic information.
(C) is a characteristic of a protein. Proteins are made from amino acids.
(D) are examples of a lipid. Lipids are commonly known as fats.
Option A should be the correct answer.
Hope this helps.
