    Q.

    Diffusion occurs only in gases

    answer choices

    True

    False

    Q.

    How do the particles move in diffusion?

    answer choices

    From a region of low concentration to a region of high concentration

    From a region of high concentration to a region of low concentration

    From a region of low concentration to a region of low concentration

    From a region of high concentration to a region of high concentration

  • Question 3

    Q.

    How does the body remove carbon dioxide from the cells?

    answer choices

    The body cells converts carbon dioxide into carbon monoxide

    The body cells don't expel the waste, they store them for future use

    The body cells expel the carbon dioxide through the use of the nucleus

    The carbon dioide diffuses out of the body cells and into the bloodstream due to differences in the concentration gradient

  • Question 4

    Q.

    The movement of particles is __________, resulting in the particles being spread throughout the container

    answer choices

    Structured

    In a straight line

    Random

    In curved, way motions

    Q.

    What does a 'region with high concentration' mean?

    answer choices

    An area with a SMALL number of particles

    An area with a LARGE number of particles

    An area with an UNEVEN number of particles

    An area with no particles

  • Question 6

    Q.

    The picture below is an example of _________________.

    answer choices

    osmosis

    isotonic

    diffusion

    active transport

  • Question 7

    Report an issue
    Q.

    How long does diffusion last?

    answer choices

    Until the concentration of particles in the system is equal

    Until a region in the system has a smaller concentration of particles than the other

    Until a region in the system has a greater concentration of particles than the other

    Until the particles disappear from the system

  • Question 8

    Q. How does the concentration gradient affect diffusion?
    answer choices
    The greater the concentration difference the faster the rate
    The smaller the concentration difference the faster the rate
    The greater the concentration the slower the rate
  • Question 9
    20 seconds
    Report an issue
    Q. How does surface area affect the rate of diffusion?
    answer choices
    Greater the surface area the slower the rate 
    Greater the surface area the faster the rate
    Smaller the surface area the faster the rate
    Surface area does not affect diffusion
  • Question 10
    30 seconds
    Report an issue
    Q.

    How does increasing temperature affect the rate of diffusion?

    answer choices

    molecules move in orderly manner

    Gives molecules more energy increasing the rate

    Takes energy away from molecules slowing down the rate

    collision of molecules slows down

  • Question 11
    45 seconds
    Report an issue
    Q. Why is diffusion important?
    answer choices
    Molecules need to be moved out of cells
    Cells need a constant supply of some molecules whilst getting rid of others
    There is no other way of transporting things in or out of a cell
    It requires energy which is always being produced and needs to be used up
  • Question 12

    Report an issue
    Q.

    Where is there a low concentration of dye?

    answer choices

    at the bottom of cup

    in the color

    at the top of cup

    no concenteraion gradient

  • Question 13
    45 seconds

    Q. The faster an object moves, the ________ kinetic energy it has. 
    answer choices
    more
    less
    none of the above
    all of the above 
  • Question 14

    Q.

    There are 24 molecules inside this cell. AFTER diffusion, how many molecules would be inside and how many would be outside?

    answer choices

    There would be 12 inside and 12 outside

    There would be 0 inside and 24 outside

    The cell will stay the same with 24 inside

    There will be 20 inside and 4 outside

  • Question 15

    Report an issue
    Q.

    Why does the tea move out of the tea bag and into the water?

    answer choices

    The warm water forces it out of the tea bag

    There is equal concentration of water and tea

    There is a higher concentration of tea in the bag and less in the water

    There is a lower concentration of tea in the bag and more in the water

  • Question 16

    Q.

    _________ particle size allows for a larger surface area to be exposed for the reaction.

    answer choices

    larger

    smaller

    Q.

    Why do large multicellular organisms need transport systems while simple unicellular organisms do not?

    answer choices

    Large organisms have a much smaller surface area to volume ratio compared to smaller ones.

    Diffusion does not work in large multicellular organisms.

    Unicellular organisms have a much smaller surface area to volume ratio than multicellular organisms.
