Answer 2

For a specimen of an active motile microorganism, the most effective microscope for visualization would be the phase contrast microscope.

• The phase contrast microscopy is a technique designed to make images of live, colorless, and transparent microbes visible by enhancing the contrast.
• Most light microscope requires that microbes are killed and stained before they can be visible.
• The phase contrast technique uses optical mechanism such that any slight variation in the phase of the organism leads to a change in amplitude and can be seen in the contrast of its image under the microscope.

In summary, the phase contrast microscope would be the most effective microscope to use when a live microbe specimen is in question due to the fact that it would use a phase change to create an enhanced image without having to kill or stain the microbe.
