So in order to form a new organism, two gametes -- the sex cells, sperm and egg -- must fuse, further mixing the genes to produce more genetic diversity. Asexual reproduction is one organism dividing into two organisms without shuffling its genes, so the offspring has the same version of genes as did the parent.
 
        
             
        
        
        
 The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities. He used similar fossils from different continents to back up his theory of continental drift. However, at that time, many scientists that had observed similarities in fossils in places like South America and Africa believed there were similar fossils in different continents because of a land bridge that were formed by two continents.
Many science communities believe that land bridges allowed migration of many different species and even people to one place to another by large bodies of water frozen by low temperature known as ice age. 
 
        
                    
             
        
        
        
Answer:
The correct answer is A When dTTP is bound to the specificity site, more dCDP is produced 
Explanation:
Ribonucleotide reductase catalyzes the conversion of ribonucleotide to deoxyribonucleotide.
                   When dTTP is bound to the specificity site at that time dCDP is produced.The So formed dCDP is converted to dUDP by the help of dCDP deaminase.The dUDP is then converted to dUTP by phosphorylation.
                Finally the dUTP is converted to dTTP by the catalytic activity of thymidylate synthase with the presence of N5 N10 methylene tetrahydrofolate.
         Thus equal amount of deoxyribonucleoside triphosphates  are maitained by the cell.
 
        
             
        
        
        
IT WOULD BE 15 CAUSE 10+5 IS 15 AND ITS THE SAME AMOUNT GOING IN AS OUT AND 15 IS GOING OUT SO 15 IS GOING IN.
