  1. Question 1

    What type of adaptation is this: enzymes in hot-spring bacteria that work at 80 °C?

    • A. structural (body shape or parts)

    Why do many desert plants open their stomata only at night?

    • A. To catch insects
    • B. To keep warm
    • C. To reduce water loss when it is cooler
    • D. Because they photosynthesise at night

    • C. functional (body processes)

  8. Question 8

    Arctic foxes have small ears; fennec foxes in the desert have huge ears. What is the best explanation?

    • A. Big ears increase surface area to lose heat; small ears reduce heat loss

    • B. behavioural (what it does)
    • C. functional (body processes)

  14. Question 14

    Emperor penguins huddle together in winter. What kind of adaptation is this and why does it help?

    • A. functional: it makes them produce venom
    • B. it has no effect on heat loss
    • C. structural: it makes their feathers longer
