Which of these is an environmental effect of building dams? a. increased water temperature upstream b. increased fertility downstream c. weed growth upstream d. sediment builds up downstream

Your answer would be B Increased fertility downstream

Explanation:

Because if we didn't have dams the world would be flooded with water and and animals would uncontrolled acidprilconstillance.

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:

regents of the university of california v. bakke, 438 u.s. 265 (1978), was a landmark decision by the supreme court of the united states. it upheld affirmative action, allowing race to be one of several factors in college admission policy.
