Can a bright field microscope be used to view living specimens?

Why some times we us blue and red with the illumination system of an optical microscope?
Blue and red filters in the illumination system of an optical microscope are used to enhance contrast and improve visibility of certain structures or specimens. Blue light is often used to highlight structures that absorb light best in the blue spectrum, while red light can help to reduce glare and improve contrast for certain specimens. The choice of filter color depends on the properties of the specimen being observed.
How is whooping cough treated?

What is the Rarest gun in the US?
There are several firearms that were the only one of its type made. As such, they would be tied for the "Most rare" category. My personal choice for the most rare (and weird) would be a revolver- the .307 Schneelock. It fired a triangular bullet. Only one specimen known to exist- and no, not a joke- that really IS the name.
