Why have improvements in microscopes over time resulted in revisions in the cell theory?

they have revealed new information about cell structure and processes.

they have made microscopes easier to use.

they have allowed scientists to share pictures of the cells being studied.

they have made it possible to confirm what scientists already suspected.

Answer;

They have revealed new information about cell structure and processes.

Explanation;

-Invention of the Microscope enhanced by a great deal the development of the cell theory as it allowed the scientists to discover that everything was made up of cells, and what cells do to come up with that theory.

-Continuous improvements in microscopes over time has enhanced new discoveries on the composition of the cell and cellular processes or functions, which has consequently led to revisions of the earlier cell theory.

Explanation:

thymine. in rna, thymine is replace by uracil

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
