Answer: To eliminate bacteria that failed to take in the plasmid.
Explanation: 
Research shows that plasmid DNA is only taken in by small percentage of bacteria in a large population.
Therefore, the need of growing transformed bacteria in the presence of ampicillin is very important. The main reason of this process is to kill off or eliminate bacteria that have failed to take in the plasmid, due to their possession of recombinant DNA plasmid pARA-R (an ampicillin resistance gene), that allows them to survive. 
However, after completion of the aforementioned procedure, the bacteria that have been transformed will be able to take in the plasmid.
 
        
                    
             
        
        
        
Answer:
<em>The correct options are A) They move to another environment.</em>
<em>B) They risk dying out.</em>
Explanation:
According to natural selection, only those organisms are able to live and survive in an environment which can adapt to the changes in an environment. Such organisms reproduce and pass on their characteristics to their offsprings.
Organisms which are not able to adapt to changes in an environment either migrate to other places or die as they are not able to survive by the changes being made.
