20 points if you answer Katie wants to learn how various amqunts of sunlight affect plant growth. Identify the Dependent Variable in her experiment
A Same plant, same soil and same amount of water
b. Various amounts of sunlight
C Plant growth

A Same plant, same soil and same amount of water

b. Various amounts of sunlight

C Plant growth​

There will be some differences in the plants. Some of the plants will grow well. Too much sunlight will cause some to die. Too less sunlight will cause them to die too.

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:

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
