To send information from the brain or spinal cord to muscles and glands - is the purpose of motor neuron
Explanation:
As part of the central nervous system (CNS), the motor neurons connect the brain and spinal cord to all the muscles and glands present all over the body and innervates them.
Their main function is to transmit nerve impulses from the CNS to the muscles, both skeletal and smooth, and directly controls the movements of the muscles of the body.
A motor neuron is a typical nerve cell with multipolar body. It can be upper of lower motor neuron.
Right from snapping of fingers to movements of hamstrings, all muscular movements functions due to impulse carried by the motor neurons.
Degeneration of the motor neurons leads to neurodegenerative diseases like spinal muscular atrophy or amyotrophic lateral sclerosis.
Explanation:
option B it is diffrentatuon of cell
I think the correct answer would be the third option. Cell membranes are present in both plant and animal cells. Both cells are eukaryotic cells so that they both contain membrane-bound organelles like the mitochondria, nucleus, lysosomes and the endoplasmic reticulum. Also, Both cells have the same processes for reproduction including mitosis and meiosis. For plant cells, additional structures can be found namely the chloroplasts, vacuoles and the cell wall. Another difference of the two would be the size. Animal cells are smaller than plant cells. Animal cells would have sizes ranging from 10 to 30 micrometers while the plant cells would be 10 to 100 micrometers.
Answer: I would think A but get a second opinion to be 100% sure, okay.
If the question were why can’t a mutated RAS gene stop uncontrolled cellular division/cancer I could easily answer the question. So if you also need that answered I could just saying.
