In costa rica, a heavy downpour provides water that quickly evaporates or is absorbed and released by the dense vegetation of the tropical rain forest. this is an example of a cycle using condensation, precipitation, and gravitational water. evaporation, gravitational flow, and adiabatic cooling. condensation, evaporation, transpiration, and green water. precipitation, gravitational flow, and convection.

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
