Your science class has taken swabs throughout the school. The image shows the
petri dish containing a bacterial culture that developed from a swab of one computer keyboard in the classroom. You would like to make a detailed observation of the internal structures of the bacteria in your culture. You know
that In order to see just their shape, it is necessary to use a magnification of
about 400x to 1000x. Based on this, develop a logical argument for using a transmission electron microscope.

A. The TEM magnifies 1,500,000X and produces a 3D image.
B. The TEM produces a 2D image of whatever specimen you are viewing.
C. The TEM magnifies up to 200,000X and you can see great detail, including the internal structure of cells.
D. In order to keep the students safe, the bacteria must be dead before viewing with any microscope.
