Acomputer model can simulate the aspects of viral reproduction quite well; however, microscopic observation of actual viral reproduction can improve understanding because actual observations
a. may reveal greater unknown complexities.
b. are easier than a computer model to view.
c. are the same each time.
d. may provide reproduction events in sequence.

I believe the answer is A.

When using an actual microscope, you can catch things that you wouldn't normally see using a computer model.

God Bless.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
