The answer is A because if you want a reliable source of scientific information you should go to an actual scientist at a scientific conference.
1) they allow for multiple reactions in the cell at once for example the mitochondria producing ATP for respiration and The Rough endoplasmic reticulum and ribosomes for protein synthesis

<h3>
What is sympathetic nervous system ?</h3>
The autonomic system is up two types such as the sympathetic and parasympathetic systems.
Both subsystem work antagonistically but in an integrated manner.
Sympathetic system is highly essential for preparing our body during emergencies for 3 F responses such as fight, fright and flight.
During this response, sympathetic system activates complex pathways for faster breathing, increased heart rate and blood pressure.
Hence, the inter-mediolateral horns of the gray matter of spinal cord is correct answer.
