Scientist believe that the formation of organic polymers, like RNA and DNA, had to move from the watery environment of the seas to solid surfaces or evaporating tidal pools because
A. dehydration is necessary for the formation of large organic polymers, too much water competes with dehydration. B. hydrolysis is necessary for the formation of large organic polymers, dehydration competes with polymerization. C. tidal pools would provide a concentrated area where more small organic molecules could aggregate. D. Kusky discovered 1.43 billion year old fossils in shallow water and tidal pools. E. sugars dissolve in water, ribose is a sugar and is necessary for the polymerization of DNA and RNA therefore being out of the water would speed up the polymerization reactions.
