Movement into and out of cells — practice question

The graph displays the impact of a larger side length for agar cubes on their surface area and volume. Which row gives the correct identification of line 1 and line 2, and of how increasing side length affects the surface area : volume ratio of the cubes?

  • Aline 1: surface area, line 2: volume, surface area : volume ratio decreases
  • Bline 1: surface area, line 2: volume, surface area : volume ratio increases
  • Cline 1: volume, line 2: surface area, surface area : volume ratio decreases
  • Dline 1: volume, line 2: surface area, surface area : volume ratio increases
