  1. 1FSH (Follicle Stimulating Hormone) is produced by the...
    1. Apituitary gland
    2. Bovaries
    3. Clungs
  2. 2In which food chain will the greatest proportion of biomass and energy of the plants be passed to humans?
    1. Aplants --> sheep --> human
    2. Bplants --> grasshoppers --> frogs --> trout --> human
    3. Cplants --> human
  3. 3Which of the following adaptations would a plant in a hot, dry climate NOT have?
    1. ADecreased surface area
    2. BLeaves are flat and wide (large surface area) to try and collect as much water as possible
    3. CWidespread roots to absorb more water
    4. DFleshy, thick stem to absorb more water
    5. EThick waxy layer to reduce evaporation, water loss and transpiration
    6. FFewer stomata to reduce evaporation, water loss and transpiration
  4. 4A vaccine prevents infection as it contains dead pathogens which are harmless but still have antigens. White blood cells in your body reproduce rapidly upon re-infection. These antibodies kill pathogens.
    1. AVerdadeiro
    2. BFalso
  5. 5A bird makes a nest with air vents. The bird opens and closes the air vents of the nest at different times of the day.

    Suggest why the bird opens and closes the air vents.

    (SELECT THREE)
    1. AOpening the vents allows CO2 in
    2. BMicro-organisms and eggs need oxygen
    3. COpening allows release of CO2 from respiration of microorganisms
    4. DOpening allows heat to come to the eggs
    5. EClosing retains moisture
    6. FOpening allows the eggs to get used to the sounds of their surroundings
    7. GOpening allows the bird to see her eggs
  6. 6The sex of a megapode bird depends on the temperature at which the egg was kept.

    Suggest why megapode birds control the temperature of their nests.
    1. AThe megapode prefers girls
    2. BMaintains sex balance
  7. 7Which of the following is NOT an adaptation an animal living in hot, dry climates (e.g camel) would have?
    1. ALong eyelashes to keep dust out of their eyes
    2. BNocturnal so they reduce sweat loss as they face the heat of the day for fewer hours
    3. CReduced amount of body fat which reduces insulating layer
    4. DSmall feet so there is a smaller surface to get burned by the hot ground
  8. 8What does a vaccine contain?
    1. AAntigens
    2. BInactive pathogens
    3. CWhite blood cells to fight pathogens
    4. DPlatelets
  9. 9Why would an animal be adapted to have large ears?
    1. AIt lives in cold climates so larger ears would mean a larger surface area to have thick fur on, so the animal could trap more hot air to keep it warm.
    2. BIt lives in hot climates so larger ears would mean a larger surface area : volume ratio so it could lose more heat.
  10. 10Apart from measles, which two other diseases does the MMR vaccine protect against? (SELECT TWO)
    1. ARubella
    2. BMeasles
    3. CEbola
    4. DFlu
    5. EMumps
    6. FMenopause
