A snow crystal appears when water vapor in the air converts directly into ice without first becoming liquid water. ... The exact shape of the final snow crystal is determined by the precise path it took through the clouds. But the six arms all took the same path, and so each experienced the same changes at the same times.
        
                    
             
        
        
        
Answer:
Option-A 
Explanation:
Pentose phosphate pathway is the alternative pathway taking place in both eukaryotes and prokaryotes parallel to the glycolysis.
The pentose phosphate pathway forms the electron carriers called NADPH and the ribose-5 phosphate.
The NADPH is formed in large amounts through this pathway which contains a very high amount of energy. NADPH can donate its hydride ions, therefore, it can be involved in the reaction where it can donate energy in the form of hydrogen and electron.
The NADPH is therefore involved in the formation of reducing biosynthetic pathways like fatty acid synthesis, cholesterol synthesis, and bile acid synthesis.
Thus, Option-A is the correct answer.

I believe your answer would be "Cell division"
DNA replication occurs just before the process of cell division which is also known as mitosis. 
Mitosis is when the cell is being divided into two and this is when DNA starts to replicate and it produces more cells and the process goes on and on and no. 
Hope this helps. c:
        
                    
             
        
        
        
Classifying things by observation can best be done by using a  : Taxon
Taxon divided organisms into different groups based on their unique similarities, which is the best way to classify things if you're doing it by observation.
