2. Cone of light
3. Fluorescent microscope
4. Knoll and Ruska
5. Photographic plate

A. UV
B. Electron microscope
C. Phase contrast microscope
D. Scanning electron microscope
E. Treponema pallidum

Answer 1

1.c ,2.e,3.b,4.d,5.uv

Answer 2

1 -E because Treponema pallidum appear as brightly illuminated
objects against a dark background.
2-C because phase contrast microscope allows the viewing of unstained specimens by using the light passing through the annular stop and forms a cone of light.
3 -A because the UV light that reflects the image of the sample stains to the fluorescence to create an image that can be viewed in fluorescence microscope.
4-B because knoll and Ruska invented electron microscope.
5-D because photographic plate are used and filmed in scanning electron microscope.
