The fill in the blank can be filled with Density of bone.

Osteoporosis is a porous condition of bone which is characterized by reduced bone density and quality. This is caused due to hormonal changes, deficiency in the bone proteins, low calcium or vitamin D.

The person with osteoporosis is prone to fractures as the bones become thin and fragile.

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.
