Correct Response: C. Photovoltaic cells have arisen in part as a result of research in the area of electrochemistry, which studies chemical reactions involved in producing electricity. A is incorrect because computer chips do not correspond to research involving the chemical analysis of DNA. Rather, they would correspond to research involving electron transfer in silicon or other metals. B is incorrect because pest-resistant corn species do not correspond to research in the area of chemical equilibrium. Rather, they would correspond to research in the area of genetic engineering. D is incorrect because synthetic fertilizers do not correspond to chemistry research in the area of molecular modeling. Rather, they would correspond to organic chemistry research.
