The correct answer is - cell must make a copy of every chromosome.
Explanation:
Mitosis is the cell cycle where cells form two identical daughter cells. It is essential to the daughter cells have a copy of every chromosome, and therefore, It copying the chromosomes during mitosis and separating the chromosome copies to provide a new cell with a complete set of chromosomes.
In the Interphase phase, the DNA breaks up evenly so that each new daughter cell has the same amount of DNA that helps in providing a complete set of chromosomes.
 
        
             
        
        
        
Answer:
 If larger seed became available, directional selection will act in favor of bigger beak finch.
Explanation:
In the case that more large seeds were to become available, then directional selection will start to influence in the beak size, favoring those individuals with bigger beaks. Those individuals with shorter beaks will start to disappear as these animals won't be able to eat the larger seed. 
Directional selection <em>increases the proportion of individuals with an extreme phenotypic trait,</em> in this case, large beaks. 
This selection presents more frequently in those cases in which <em>interactions between living organisms and the environment</em> modify in the same direction.
