Cells tend to be small, with sizes ranging between 1 and 100 mm. These small sizes help to ensure that cells have a favorable surface-area-to-volume ratio. Choose the statement that explains why a favorable surface-area-to-volume ratio is advantageous.
Higher surface-area-to-volume ratios improve the efficiency of transporting materials in and out of cells.
Lower surface-area-to-volume ratios improve the efficiency of transporting materials in and our of cells.
Higher surface-area-to-volume ratios speed up the flow of cytoplasm within cells.
Higher surface-area-to-volume ratios slow down the flow of cytoplasm within cells.
The Endosymbiotic Theory suggests that eukaryotic cells evolved when an ancient cell engulfed another, forming a permanent symbiotic relationship. Choose the evidence that best justifies this claim.
