3. How did the invention of the light microscope
lead to the development and refinement of cell
theory over time?
A. Cells could now be seen in very low light so
that studies of reproduction could take place at
night.
B. Light microscopes allowed for the visualization
of internal cell parts at magnifications over
1,000 times.
C. As microscopes became more powerful,
scientists could see additional structures and
functions within the cell.
D. Scientists kept what they saw through the lens
of the light microscope to themselves to be sure
they got all the credit for the discovery.

Which series lists the correct order of steps of binary fission from first to last? sex pilus connects two cells ® plasmid dna is transferred ® complementary dna strands are created ® cells separate live cells bind to degraded cells ® dna is transported across the membrane ® dna is incorporated into recipient's dna virus infects bacterial cell, new viruses are made ® dna is assembled in new virus ® new virus infects another bacterial cell and transfers dna dna is copied ® dna molecules attach to cell membrane ® cell membrane elongates and pinches off ® two identical cells are produced
