a. Give one advantage and one disadvantage of a light microscope.

Advantage of a Light Microscope: One major advantage of a light microscope is its ability to magnify small objects to a size that can be seen by the human eye. This allows for the detailed study of cells, bacteria, and other microscopic organisms that would otherwise be invisible.

Disadvantage of a Light Microscope: One major disadvantage of a light microscope is its limited resolution. Due to the wavelength of visible light, there is a limit to how much a light microscope can magnify an object while still maintaining a clear image. This means that extremely small objects, such as individual molecules or atoms, cannot be seen using a light microscope.
