At least half of the world’s species of land organisms live in a.. a) tropical rain forest. b) temperate savanna. c) temperate forest. d) tropical desert.

A) Tropical rain forest.

This is one of the myriad reasons that it is vital that we protect and preserve our rain forests.

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:

the answer is 95 degrees
