Answer:
True
Explanation:
 In  phase-contrast objective and a phase contrast optical systems is equipped with Light microscope  .
Phase contrast microscope is used to differentiate unstained structures in a cell  that differ in refractive indices and thickness. Thus it is usefull for examining  living unstained organisms.
Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.
Hoping this might help!!!
 
        
             
        
        
        
Answer:
D. All of the above
Explanation:
Just as when we grow and need more food and energy so does a cell. when a cell is growing there is more of it that can be utilized putting more stress on the DNA to code whatever it needs. The bigger the cell is the denser and thicker the cell membrane gets making it harder for materials to work its way in and out of the cell.
