Questions and Answers

Which environment has a higher heat capacity?

  • Both have the same heat capacity
  • Living in water (correct)
  • It is not mentioned in the text
  • Living on land

    • Which statement about gas exchange is accurate for aquatic animals?

  • Less oxygen available, higher density and viscosity make it more energy-consuming to move water over a respiratory surface (correct)
  • It is not mentioned in the text
  • More oxygen available, lower density and viscosity make it easier to eliminate CO2
