Ascientist wants to examine living cells lining the respiratory tract to determine how the cells use tiny hairs to move dirt and mucus away from the lungs. which one of the following instruments would be best, and why?
a. a light microscope, because it allows observations of whole, live cells
b. a transmission electron microscope, because it has high resolving power
c. a transmission electron microscope because it is capable of very high magnification
d. a scanning electron microscope, because it can reveal structures on cell surfaces
e. a scanning electron microscope, because it can be used to observe whole cells without slicing them

A light microscope, because it allows observation of whole, live cells

Explanation: The electron microscopes (transmission and scanning) cannot and should not be used with living cells because the electrons utilized will destroy the living cell. It is important to highlight the differences between the three types of microscopes listed above.  The transmission electron microscope uses electrons to create an image through the sample which can be magnified and focused onto a device than can then produce an image. The scanning electron microscope uses electrons to provide an image by scanning the sample. The light microscope is the normal microscope that is used in all laboratories. As stated in the name, light microscopes use light and magnifying lenses to view the sample. The light and lenses allow the sample to not be affected if it is a living sample.  

answer; i believe the correct answer is (data); /// good luck
