What is one significant way that modern microscopes have impacted our understanding of biology?

Multiple Choice

Which of the following is a primary difference between compound microscopes and dissecting microscopes?

• Compound microscopes are used for thin specimens and offer higher magnification, while dissecting microscopes provide 3D viewing of opaque objects with lower magnification.

• Compound microscopes use only one lens, while dissecting microscopes use multiple lenses.

• Dissecting microscopes are used for viewing living cells, while compound microscopes are not.

• Compound microscopes are portable, while dissecting microscopes are stationary.
