Mass number = protons + neutrons
If you have the # of protons and the mass #, subtract the number of protons from the mass number to get the number of neutrons.
If you have the number of neutrons and the mass number, subtract the number of neutrons from the mass number to get the number of protons.
        
                    
             
        
        
        
Answer:
Receiving sensory information and carrying commands to the muscles.
Explanation:
The spinal cord serves as the transmission conduit  for the passage of action potential as sensory information through the sensory/afferent neurons to the dorsal roots of the spinal cord.The information  synapse with the inter neurons,branching off to the brain and emerged as the  response through the motor/efferent neurons to the effectors(muscles).
This pathways is called reflex arc. Thus most of the involuntary action of the body is conducted through the spinal cord
 
        
                    
             
        
        
        
They are known as evolutionary biologists. Strictly speaking, anthropology is split up into a number of disciplines - physical (sometimes known as biological) anthropology is the study of evolution as it relates to human beings. Further to this, scientists who study evolution in the fossil record are known as evolutionary palaeobiologists or simply palaeobiologists.
