A. RNA polymerase simultaneously transcribes both strands of DNA

Chapter 16 mentioned that less than 3 percent of the water on Earth is freshwater. There are

organisms that have adjusted to the salinity of the oceans, but humans are not among them. Therefore, scientists are working on various desalination procedures—methods of removing the salt from ocean water. These desalination procedures are quite expensive and require advanced technology. Aside from the cost, what do you see as other potential drawbacks of performing desalination on a large scale?
