Answer:
more individuals are produced each generation that can survive. phenotypic variation exists among individuals and variation is heritable. those individuals with heritable trails better suited to the environment will survive. 
 
        
             
        
        
        
Predation- Predation is a biological interaction where a predator (a hunting animal) kills and eats its prey (the organism that is attacked).
Commensalism—A relationship where one species obtains food or shelter from the other species.
Mutualism—A relationship where both species benefit from the relationship.
        
                    
             
        
        
        
Answer:
When an E.coli cell is infected by multiple phages,they will take either lytic or lysogenic pathway.
Explanation:
When lambda phage bacteriophage infects an E.coli,it can either undergo lytic cell growth and lyse the host cell or enter lysogenic pathway.
The operator region of lac operon in E.coli contain single repressor binding site whereas the lambda operators  and
 and  each contains 3 repressor binding sites (
  each contains 3 repressor binding sites ( and
 and  )  that are differently occupied under different conditions.
)  that are differently occupied under different conditions.
The differential affinity of lambda repressor for the three binding sites in these operators play an important role in the maintenance of lysogenic state of lambda prophage in E.coli.
The lytic development occurs in cells infected with lambda phage that carry   gene.
 gene.
In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.
