Answer:
Water is transported from one area to another area that has little water.
Water is collected and salt allowed to settle at the bottom.
Explanation:
Desalination of water is a process of the removal of salts and minerals from the water. This process is used for the production of water suitable for human consumption or irrigation.
Natural desalination occurs trough the hydrologic cycle when seawater evaporates. On the other hand, manipulated desalinization is an energy expensive alternative to natural desalination.

Explanation:
Answer:
The gene for beta-galactosidase turns off.
Explanation:
The gene that codifies the beta-galactosidase enzyme is part of the <em>lac</em> operon, which also contains two other genes that produce enzymes involved in the metabolization of lactose.
Between glucose and lactose, the bacteria will preferentially use glucose as an energy source. On the other hand, lactose is a dimer, and thus a series of enzymes are needed to process lactose before its use as an energy source.
If there is no lactose present, the genes contained inside this operon are turned off (the operon is repressed).
