As per the mechanism, the waves can be distinguished as electromagnetic and mechanical waves. Electromagnetic waves are those fluctuations that have no mechanism to progress whereas mechanical waves demand a mechanism for their communication. Electromagnetic waves progress in a vacuum whereas mechanical waves don't have.
 
        
             
        
        
        
Answer:
The correct answer is the endocrine system. 
Explanation:
The sympathetic division of the autonomic nervous system and the endocrine system are the two prime systems that take part in the stress response.  
At the time of acute or chronic stress, the endocrine system first makes the hypothalamus to discharge CRH or corticotropin-releasing hormone into the bloodstream. The release of CRH further makes the anterior pituitary to discharge ACTH or adrenocorticotropic hormone into the blood. This further stimulates the adrenal cortex to discharge cortisol, that is, one of the glucocorticoid hormone into the bloodstream.  
The cortisol finally makes the organs and tissues present within the body to effectively cope up with the initial stress stimulus.  
 
        
             
        
        
        
Food was cooked, quickly frozen, and then dehydrated in a special vacuum chamber. Freeze-dried food didn't need to be refrigerated and would last a long time. To make most freeze-dried foods, astronauts squeeze water into the food packages and then eat the food after it absorbs the water.
