Which of the following correctly ranks these three categories from least dense to most dense? A. Earths crust, human beings, earths atmosphere

B. Human beings, Earth’s crust, earths atmosphere

C. Earths atmosphere, human beings, earths crust

C

Explanation: Earth's atmosphere isn't very dense because it is made of air, which floats. Human beings are denser then air since they are solid, but not as dense as Earth's crust, which is rocky and the densest out of the three.

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:

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
