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

A. They have revealed new information about cell structure and processes.
B. They have made microscopes easier to use.
C. They have allowed scientists to share pictures of the cells being studied.
D. They have made it possible to confirm what scientists already suspected.

Cell Structures under the Microscope. The microscope was improved and modified for better observation of different cells and microscopic organisms. As a result, cell theory was created and modified to be what we know today. The physiological and biological study of cells focuses on cellular structure and function.

Explanation:

I'd say it would be A.

Explanation:

I say it's "A," because the other answer choices, in my opinion doesn't make as much sense "A" does.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
