The diagram depicts two agar cylinders. Both cylinders are put into a dye solution at the same time. The time needed for the dye to diffuse to the centre of each cylinder is measured. Which statement explains why the dye reaches the centre of one agar cylinder more quickly than the other agar cylinder?
- AThe dye reaches the centre of X in a shorter time than the dye reaches the centre of Y because X has a larger surface area to volume ratio.
- BThe dye reaches the centre of X in a shorter time than the dye reaches the centre of Y because X has a larger surface area.
- CThe dye reaches the centre of Y in a shorter time than the dye reaches the centre of X because the dye has a shorter distance to diffuse to the centre.
- DThe dye reaches the centre of Y in a shorter time than the dye reaches the centre of X because Y has a smaller volume.
