Answer:
There must have two white genes to become white. 
Explanation:
In order to a mouse to have white fur, both of their genes must be white. In the punnet square, you have a Black (BB) and a white (bb). If they have offspring, all of them have one black (Dominant) and one white (recessive). The black gene overpowers the white gene, so they come out black.
 
        
                    
             
        
        
        
Since Jordan needs to use the high power objective in order to view the specimen under the light microscope. He should use the ocular lens in order to view the high power objective which is placed in the objective lenses. So he needs to use the ocular lens for viewing and the objective lens to magnify and see the specimen clearly on the stage.
