A scientist uses a computer to make a model of DNA, the genetic material that determines inherited characterstics in living things. DNA is found inside the cells of all living things. The model looked like the figure below. Which of the following is a reason that a scientist would want to use a model to study DNA?

elements make up everything, and they combine to make compounds.

the answer is c

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
