A scientist needs to study blood cells for medical research. Why might a computer model benefit the scientist?
O A. The blood cell is too large to study, and the model is smaller.
B. The model would enable the scientist to see what the flow of
blood cells would look like when slowed down.
C. The model can be adjusted until the scientist gets the desired
results.
D. Using the model will give more accurate study results.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
