5 Evidences of Evolution

Which cells are more efficient at obtaining nutrients?

• Small Cells
• Medium Size Cells
• Large Cells
• X-Large Cells

This image shows how materials move into various sized cells in a given amount of time.... why does one square cell have more pink coloring than the others? 

• The surface area was too larger to get through
• The volume of the other cells was too large for the dye to get through
• There was not enough surface area for the dye to get through
• The volume was too low for the dye to stay in the square
