Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
        
             
        
        
        
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
•	Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
•	Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
 
        
             
        
        
        
Answer/Explanation:
Using solar energy, photosynthesis uses carbon dioxide and water to produce glucose and oxygen, whereas respiration uses glucose and oxygen to produce energy, releasing carbon dioxide and water.
Therefore, photosynthesis and respiration act as a cycle, using reverse reactants and products. 
Photosynthesis builds food for the cell to use, respiration uses this food to power cellular processes.
