I’m not sure that your choices are because it says select all that apply but I would tell the mother to stop giving the baby cows milk. The baby needs more iron which is in breast milk or formula if not she can become anemic and cows milk is not easy to digest for babies.
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.
