What characteristics of water is most to fish in a lake

D. water is able to hold dissolved oxygen

Explanation:

Dissolved oxygen (DO) can enter water by diffusing across the surface of water from the air, or as a byproduct of photosynthesis by other aquatic organisms like plants and algae. Each aquatic organism, like land-dwellers, has specific oxygen requirements. Fish use DO for the process of respiration, where they obtain oxygen from the surrounding water using their gills. Anoxic conditions, where oxygen levels are low usually result in significant deaths in fish populations.

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.
