Questions and Answers

What is the surface-area-to-volume ratio used to explain in science and engineering?

  • Water loss by animals
  • Thermoregulation in organisms
  • Diffusion of small molecules like oxygen and carbon dioxide (correct)
  • Bacterial morphogenesis

    • How does the surface-area-to-volume ratio affect the diffusion or heat conduction rate?

  • SA:V is only relevant for biological structures
  • Lower SA:V leads to faster diffusion or heat conduction
  • Higher SA:V leads to faster diffusion or heat conduction (correct)
  • SA:V has no impact on diffusion or heat conduction rate

    • What does a small size imply in terms of surface area to volume ratio?

  • Small size implies a large ratio of surface area to volume, maximizing nutrient uptake (correct)
  • Small size implies a small ratio of surface area to volume, minimizing nutrient uptake
  • Small size implies a balanced ratio of surface area to volume
  • Small size implies no impact on nutrient uptake
