  1. 1[blank_start]diffusion[blank_end] is the process that moves gases across the surface of gaseous exchange very slowly down a concentration gradient.
    1. Adiffusion
  2. 2Which of the following is not a property of a gaseous exchange surface?
    1. Ait must be thin
    2. Bit must have a small surface area
    3. Cit should have a good air and blood supply
    4. Dit must be a moist surface
  3. 3the gaseous exchange surface in animals are called [blank_start]alveoli[blank_end] while that of fish are called [blank_start]gill lamellae.[blank_end]
    1. Agill lamellae.
    2. Balveoli
  4. 4The gases diffused faster when dissolved in a liquid thus the gaseous exchange surface must always be kept [blank_start]moist[blank_end]
    1. Amoist
  5. 5the gaseous exchange surface of a worm is its
    1. Alungs
    2. Bstoma
    3. Ccell membrane
    4. Dskin
  6. 6the [blank_start]thinness[blank_end] of a G.E.S. helps to reduce the distance for gases to travel while its [blank_start]large surface area[blank_end] ensure there is maximum surface absorption.
    1. Athinness
    2. Blarge surface area
  7. 7The [blank_start]gill rakers[blank_end] filter the the water of particles before the water envelopes the G.E.S. OF [blank_start]gill lamellae[blank_end] of the fish.
    1. Agill rakers
    2. Bgill lamellae
  8. 8Identify a property of a gaseous exchange surface that is essential for terrestrial animals but not for aquatic animals
    1. Aa large surface area
    2. Ba moisture layer
    3. Ca good blood supply
    4. Da good air supply
  9. 9The practice of free style diving that is diving on one breathe of air or holding ones breathe under the water for an extended time >2 minutes causes what positive change in a person's lungs
    1. Aincreases moisture production resulting in faster diffusion
    2. Bincreases air supply to the G.E.S. resulting in more air available
    3. Cincreases the surface area resulting in more efficient absorption of oxygen from air
    4. Dincreases the rate of blood flow for faster oxygen transport
  10. 10It is said that the larger an organism gets there is an increase in its surface area to volume ratio
    1. AVerdadero
    2. BFalso
