Answer:
B
Explanation:
B is the most likely consequence because of the following facts we are told:
- After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees
 - Adult apple maggots will only mate on the type of tree on which they were born.
 
This provides a geographical isolation (because they are feeding and laying eggs on separate trees) and reproductive isolation (because they will only mate on the type of tree on which they are born).
These two factors increase the chances that apple maggots feeding on apple trees will only encounter those who have mated on the same tree, and continue to mate this way. Over time, the populations (i.e. apple tree vs hawthorn tree) will intermix less and less. This will mean the genetic pool will become distinct, and natural selection will be acting differently (different habitats and different genes), encouraging speciation. 
 
        
                    
             
        
        
        
Answer:
Increase aldosterone and decrease ADH
Explanation:
Aldosterone causes reabsorption of sodium ions while Antidiuretic hormone (ADH) causes reabsorption of water. Aldosterone also causes water reabsorption due to increased osmotic pressure by reabsorbing sodium ions. But for water reabsorption, Aldosterone has to work along with ADH to increase permeability for water. If we increase Aldosterone and decrease ADH, the sodium ions will be reabsorbed while water cannot be reabsorbed due to decreased permeability of DCT and collecting tubules for water.
