Questions and Answers

Why is SA:V an important concept in science and engineering?

  • It determines the weight of an object relative to its size
  • It measures the density of an object or collection of objects
  • It calculates the total area of an object
  • It explains the relation between structure and function in processes occurring through the surface and the volume (correct)

    • How does SA:V relate to the diffusion of small molecules like oxygen and carbon dioxide?

  • SA:V has no relation to the diffusion of small molecules
  • SA:V only affects the diffusion of large molecules
  • The larger the SA:V, the faster the diffusion of small molecules (correct)
  • The smaller the SA:V, the faster the diffusion of small molecules

    • What does SA:V stand for?

  • Volume-to-surface ratio
  • Size-to-volume ratio
  • Surface-area-to-volume ratio (correct)
  • Surface-to-area ratio
