The 20 questions

  1. What are the three main types of biological adaptations?

    • structural, behavioural, functional
    • active, passive, neutral
    • inherited, acquired, learned
    • physical, chemical, mental

  2. A bird migrates south in winter. What type of adaptation is this?

    • physiological
    • functional
    • behavioural
    • structural

  3. Organisms living in very extreme conditions are called what?

    • extremophiles
    • decomposers
    • consumers
    • producers

  4. Which organisms are prime examples of extremophiles?

    • freshwater trout
    • temperate oak trees
    • deep-sea bacteria
    • common garden snails

  5. What do adaptations primarily enable organisms to do?

    • stop all mutation
    • survive normal conditions
    • change their habitat
    • increase body size

  6. A feature that helps survival in the normal environment is what?

    • a biotic factor
    • an adaptation
    • a mutation
    • a classification group

  7. Which of these is classified as a functional adaptation?

    • mimicking leaf shapes
    • migrating in winter
    • secreting toxic venom
    • having thick fur

  8. Which physical feature is an example of a structural adaptation?

    • hibernating in winter
    • producing venom
    • thick fur coat
    • migrating south

  9. A desert plant has a waxy coating to reduce water loss. Which type of adaptation is this?

    • functional
    • behavioural
    • biotic
    • structural

  10. A nocturnal animal hunts at night to avoid competition. Which type of adaptation is this?

    • behavioural
    • physiological
    • functional
    • structural

  11. A bacterium at a deep-sea vent has enzymes that work at very high temperatures. Which type of adaptation is this?

    • structural
    • biotic
    • behavioural
    • functional

  12. Which action represents a behavioural adaptation?

    • flocking together
    • having camouflage
    • producing poison
    • having sharp claws

  13. Why are adaptations essential for species survival?

    • preventing all disease
    • accelerating growth rate
    • ensuring environmental fit
    • eliminating predators

  14. A camel stores fat in its hump. Which type of adaptation is this?

    • abiotic
    • biotic
    • structural
    • behavioural

  15. What structural adaptation helps fish move efficiently through water?

    • streamlined body shape
    • thick scaly skin
    • large flat fins
    • gills for breathing

  16. Why must enzymes in extremophiles be specially adapted?

    • extreme conditions
    • low pressure environments
    • neutral pH levels
    • constant room temperature

  17. How do advantageous adaptations typically arise in populations?

    • mutation and selection
    • conscious animal choice
    • rapid clonal splitting
    • direct environmental stress

  18. How do structural and behavioural adaptations differ?

    • genetic versus learned
    • physical versus action
    • internal versus external
    • fast versus slow

  19. What do extreme environmental conditions challenge in organisms?

    • cell division
    • genetic mutation
    • enzyme function
    • active transport

  20. Which adaptation strategy best helps an animal survive in a very cold environment?

    • large ears
    • thin fur
    • thick blubber
    • high sweating
