Question

what did the invention of the microscope allow scientists to do?
□ examine cells
□ view the macroscopic world
□ study space
□ observe ocean depths

Explanation:

Microscopes are used to magnify small - scale objects. Cells are too small to be seen with the naked eye and can be examined using a microscope. The macroscopic world can be seen without a microscope, space study requires telescopes and other space - related instruments, and observing ocean depths requires submersibles and sonar etc., not microscopes.

Answer:

examine cells
