Answer:
By the removal of salts.
Explanation:
The desalination process is used to remove salts from the ocean or sea water. This method can be used to provide drinking water for the people of Middle East. This method is used in the middle east because there is scarcity of water due to desert area and these countries are located near the sea so they can use the sea water for drinking purpose with the helps of desalination process. Saudi Arabia, the United Arab Emirates, Kuwait, and Bahrain are the countries which are used this method.
Answer:
Replicating DNA is fragile, and can break during the duplication process. In fact, broken chromosomes are often the source of DNA rearrangements and can change the genetic program of a cell. These changes can trigger a growth advantage in a single cell in your body, and when that cell continues to divide, tumors arise. Fortunately, our cells have defense mechanisms to shield us from these damaging events.
Sexual reproduction plays an important role in variation such that; production of unique gametes during meiosis, and the random combination of male and female gametes upon fertilization provides a large amount of variation (option A).
<h3>What is sexual reproduction?</h3>
Sexual reproduction is the process whereby a new organism is created by combining the genetic material of two organisms.
During sexual reproduction, organisms produce gametes through a process called meiosis.
This meiosis allows genetic diversity in the unique gametes produced, which causes random combination of male and female gametes upon fertilization provides a large amount of variation.
