Question

which of the following are functions of both light microscopes and dissecting microscopes? 100x objectives are used for viewing organisms dust is removed by vacuum tubes. specimens are illuminated using a light source. organisms and their structures are displayed using computers.

Explanation:

• Light microscopes and dissecting microscopes both need to illuminate specimens to view them. A light source is used for this purpose in both types.
• 100X objectives are not typically used in dissecting microscopes (which have lower magnification).
• Vacuum tubes for dust removal are not a common function of these microscopes.
• Displaying using computers is not a fundamental function that both share in the basic operation (they can be connected to computers but it's not a core shared function like illumination).

Answer:

Specimens are illuminated using a light source.
