Contact [7]

According to the research, the correct answer is fiber composites. Because cell walls consist of a cross-linked network of long filaments embedded in a stiff surrounding material, they can be called fiber composites.

<h3>What are cell walls?</h3>

It is a network that covers prokaryotic cells and plant cells that is located outside the plasma membrane, helping to form the structure.

In this sense, since it is made up of a network of carbohydrates, phospholipids and structural proteins, and the different cell types of plants can be identified by their characteristics, they can be called fiber composites.

Therefore, we can conclude that cell walls are a network embedded in a matrix composed of carbohydrates and proteins.

Which of the following are NOT functions of the spinal cord?
maksim [4K]

Answer:

Reflexes are not a function of the spinal cord.

Explanation:

The spinal cord is part of the central nervous system and is made up of neurons that go along it (from the end of the brain stem almost to the bottom of the spine).

The spinal cord receives incoming messages from the peripheral nervous system (including the sensory neurons) and pass on messages from the brain to efferent neurons (motor neurons at muscles).

The spinal cord contributes to learning as it passes on the info received from sensory neurons (that there is an obstacle in the path) to the brain and passes on the response from the brain to the muscles (to lift the foot up higher).

The spinal cord is essential for integration as it passes on sensory information  to the brain to determine motor output.

Reflexes are when sensory information is quickly sent straight to motor neurons to move. It does not need to go to the brain (hence does not need to go to the spinal cord) for the reaction as it would be too slow. This is seen when someone who is paraplegic (paralysed at lower torso) can still move their leg in response to the doctor tapping their knee even when they cannot forcibly move their legs.

Therefore reflexes are not a function of the spinal cord.
