What is true about the structure or function of the plasma membrane? A: The bilayer structure forms a solid boundary that separates the cell from its environment.

B: Large molecules often cross the plasma membrane while inside vesicles.

C: Hydrophobic molecules keep the cell from getting too much water.

D: It is made entirely of integral proteins.

B: Large molecules often cross the plasma membrane while inside vesicles.

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.
