What could be the reason that some birds hide their eggs on high trees on a certain island while others hide them between rocks on another island?

Different places, different predators, different environmental occurrences, which means the bird have to change their ways in order to protect their young.

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.

explanation:

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition
