The ratio of the volume of typical eukaryotic :prokaryotic cells is 1000:1
Explanation;
-Eukaryotic cells are generally much larger than prokaryotic ones and this difference in volume has several implications. One advantage is that bigger cells can afford to have more things stored in the cytoplasm such as organelles. This means it is not as costly to a eukaryotic cell to have structures taking up space. In a prokaryote, space is at a premium and anything not being used is pretty rapidly degraded.
-If the diameter of a typical eukaryotic cell is approximately ten times the diameter of a typical prokaryote, then it means the linear scale factor or the ratio of the lengths (diameter) is 10:1.
-The volume scale factor or the ratio of the volumes is got by getting the cube of the ratio of the length (diameter). Thus;
Capillaries are one cell thick and so this makes them very thin. capillaries are also arranged in networks known as capillary beds, and thus multiple capillaries are spread over a large area.
I believe B) I think because if there are more animals nothing is going to change but the supplys like food and shelter may decrease but that's not an option
