The 20 questions

  1. What main advantage does sexual reproduction provide to offspring populations?

    • Genetic identity
    • No mate needed
    • Genetic variation
    • Faster reproduction

  2. Which process acts on variation in offspring when the environment changes?

    • Asexual cloning
    • Cell differentiation
    • Natural selection
    • Selective breeding

  3. Which method do humans use to speed up natural selection for food production?

    • Asexual cloning
    • Genetic cloning
    • Binary fission
    • Selective breeding

  4. How many parent organisms are required for asexual reproduction?

    • Two
    • One
    • Three
    • Four

  5. Why is asexual reproduction more time and energy efficient than sexual reproduction?

    • Requires two parents
    • No mate needed
    • Produces variation
    • No cells needed

  6. When are many identical offspring produced during asexual reproduction?

    • Extreme temperatures
    • Unfavourable conditions
    • Favourable conditions
    • Changing environments

  7. In which host do malarial parasites reproduce asexually?

    • Tsetse fly host
    • Snail host
    • Mosquito host
    • Human host

  8. Which organisms reproduce asexually by spores but also reproduce sexually to give variation?

    • Daffodils
    • Strawberry plants
    • Malarial parasites
    • Many fungi

  9. Strawberry plants spread by which structure?

    • Gametes
    • Seeds
    • Pollen
    • Runners

  10. Daffodils reproduce asexually by which method?

    • Bulb division
    • Spore release
    • Fertilisation
    • Budding

  11. Which is an advantage of asexual reproduction in favourable conditions?

    • Rapid population growth
    • High genetic variation
    • Slow offspring production
    • Increased mutation rate

  12. Which type of reproduction provides a survival advantage if the environment changes?

    • Asexual reproduction
    • Binary fission
    • Vegetative propagation
    • Sexual reproduction

  13. Which process uses variation from sexual reproduction to increase food production?

    • Genetic cloning
    • Selective breeding
    • Asexual propagation
    • Tissue culture

  14. What is a major disadvantage of asexual reproduction?

    • Lack of variation
    • Slow reproduction speed
    • High energy cost
    • Needing two parents

  15. Why is sexual reproduction less time-efficient than asexual reproduction?

    • Producing genetic clones
    • Finding a mate
    • High mutation rate
    • Fast cell division

  16. What determines whether some organisms reproduce sexually or asexually?

    • Parent organism age
    • Daylight hours
    • Random chance
    • Environmental circumstances

  17. What is the main advantage of asexual reproduction in stable environments?

    • Identical offspring
    • Higher mutation rate
    • Slower growth rate
    • Increased genetic variation

  18. In which host do malarial parasites reproduce sexually?

    • Human host
    • Human liver
    • Red blood cell
    • Mosquito host

  19. What advantage do asexual bulbs give plants over sexual seed production?

    • Greater genetic variation
    • Faster reproduction
    • Disease resistance
    • Better seed dispersal

  20. What primary biological mechanism creates genetic diversity during sexual reproduction?

    • Meiosis
    • Binary fission
    • Mitosis
    • Budding
