Answer:
D. By blocking fish migration.
Explanation:
The pictured waterfalls are artificial.
The construction of the wall to raise water level for the falls to be created cuts the contact between marine organisms.
The fish on the other end of the fall cannot freely migrate to the other side.
This is because the falls are too dangerous for them and can lead to their death.
This means that the pictured method of power generation is not environmental friendly.
The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material. The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus. Instead, their DNA floats around inside the cell.

The organelles of the cells are located in the cytoplasm where the different chemical reactions happen.
</span>Mitochondria is the power house of the cell and uses ATP to produce biological energy which is used for the cell functions. And Golgi bodies are the organelles responsible for packing, modifying and transportation of proteins and enzymes from the ER. Cell membrane is the covering outermost layer of an animal cell.<span>
