Answer:True 
Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :
1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing 
2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing. 
 
        
             
        
        
        
Well they can begin as cosmic rays colliding with water molecules to create clouds. Hope this helps :)
        
                    
             
        
        
        
Because it is the evolution ary process that the caterpillars is designed to go through according to this species.
        
             
        
        
        
A) taking in extra water can result in cramps so it is not A
B)you should do warm up,So that the body would be ready to handle the sudden increase in body speed,So it is not B
C)working through any pain,is good at some reason but not on all the experience so its not C
D)you need to plan on taking proteins,Proteins helps in strengthening in bones and helps in the supply of oxygen to the cells(for eg tennis players eat a banana before,middle and after the game or gym workers take protein bars to work out more)
