The answer is graded potential<span>. Its made of various action potentials that depolarise the neuron incrementaly, in short interspersed intervals that do not give time for the neurons to return to resting potential. Therefore, the actions potentials, of varying sizes, grade up in  sum and when they cumulatively reach the threshold level, they invoke an impulse in the nerve</span>

Answer: it contains the instructions needed for an organism to grow, reproduce, develop, and survive.
Explanation:
All of the structure of the DNA molecule work together to grow, reproduce, develop, and survive.
 
        
                    
             
        
        
        
The pyloric sphincter is compose of smooth muscle and is located between the pylorus in the stomach and duodenum of the small intestine. In digestion, it serves as a valve controlling the flow of food thus it prevents the contents of small intestine backing up into the stomach.
