13. Scientists compared fossil remains of a species that lived 5,000 years ago with members of the same species living today. Scientists concluded that this species had changed very little
over the entire time period. Which statement best accounts for this lack of change?
A. The environment changed significantly and those offspring without favorable
characteristics died.
B. The environment changed significantly, but the species had no natural enemies for a
long period of time.
C. The environment did not change significantly and those offspring expressing new
characteristics survived their natural enemies.
D. The environment did not change significantly and those offspring expressing new
characteristics did not survive.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
