1. What is an animal 'adaptation'?
- A feature or behaviour that has evolved over time to help an animal survive in its environment
- An animal's ability to change colour instantly
- When an animal changes habitat during its lifetime
- When an animal learns a new skill from its parents
2. Camouflage is a common adaptation. Which of these animals uses 'disruptive colouration' β bold patterns that break up its outline rather than blend in?
- Arctic hare (white fur)
- Leaf-tailed gecko (looks like bark)
- Stick insect (looks like a twig)
- Zebra (black and white stripes)
3. What is 'mimicry' as an animal adaptation?
- When a harmless animal copies the appearance of a dangerous animal to fool predators
- When an animal changes colour to match its background
- When an animal copies sounds from its environment
- When young animals copy their parents' behaviour
4. Which adaptation does the Arctic hare use in winter to avoid predators?
- It burrows underground to hide
- It hibernates and avoids predators by sleeping
- It migrates south to escape predators
- Its fur turns white to match the snow
5. What is hibernation and which animals use it as an adaptation?
- A daily rest period taken during the hottest part of the day
- A deep winter sleep where metabolism slows dramatically to survive food scarcity β used by bears, hedgehogs, and dormice
- A long migration to warmer climates during winter
- A period of reduced activity only lasting a few days
6. The giraffe's long neck is a classic example of adaptation. What does it help the giraffe do?
- All of the above
- Reach leaves in tall trees that other animals cannot access, giving them an exclusive food source
- Reach water without kneeling dangerously
- Spot predators from a greater distance
7. What is 'aposematism' in animal adaptation?
- A defensive spray used to deter attackers
- The ability to inflate the body to appear larger
- The ability to produce and use venom
- Warning colouration β bright colours that signal to predators that an animal is toxic or dangerous
8. The Arctic fox has very small ears compared to its desert-dwelling relative, the fennec fox. Why?
- Arctic foxes evolved from a different ancestor than fennec foxes
- Arctic foxes hunt by sound less than fennec foxes
- Small ears lose less heat β large ears would be a disadvantage in extreme cold
- Small ears provide better camouflage in snow
9. What is 'convergent evolution' and give an example?
- When one species gradually becomes another species
- When two related species diverge into different forms
- When two species evolve away from each other
- When unrelated species independently evolve similar adaptations to similar environments or challenges
10. The woodpecker has several adaptations for hammering wood. Which of these is NOT a real woodpecker adaptation?
- A beak lined with rubber-like material to absorb impact
- A shock-absorbing skull with thick spongy bone
- A very long, barbed, sticky tongue that wraps around the brain for storage
- Strong feet with two toes forward and two backward for gripping tree trunks
11. What adaptation do animals like sharks, tuna, and dolphins share that makes them fast swimmers?
- All three adaptations together
- Countershading colouration β dark on top, light below
- Fusiform (torpedo) body shape that minimises water resistance
- Identical shaped tails
12. Why do some deep-sea fish produce their own light (bioluminescence)?
- To attract prey, communicate with mates, or confuse predators in the pitch-black deep ocean
- To photosynthesize like plants
- To scare off large predators with a blinding flash
- To warm the cold water around them
13. The bombardier beetle has one of the most remarkable chemical defences in the animal kingdom. What does it do?
- It electrocutes predators with a generated electrical charge
- It mixes two chemicals in its abdomen that react explosively, firing a boiling toxic spray at predators with a loud bang
- It releases an extremely sticky glue that seals a predator's mouth shut
- It sprays cyanide gas
14. What is 'countershading' in fish and marine animals?
- Being dark on top and lighter below, making the animal harder to see from above and below
- Changing colour to match colourful coral backgrounds
- Having identical patterns on both sides of the body
- Producing bioluminescence to counter darkness
15. Some animals practise 'thanatosis' as a defence mechanism. What is it?
- Making themselves appear much larger
- Playing dead β becoming completely limp and motionless to deter predators
- Secreting toxic chemicals through the skin
- Shedding a body part to escape
16. The electric eel generates electricity. What adaptations make this possible?
- A specialised organ that absorbs static electricity from the water
- Copper-based blood that conducts electricity
- Small crystals in its scales that generate piezoelectric charges
- Special cells in its skin called electrocytes that act like biological batteries, stacked in columns
17. What is 'autotomy' and which animals use it as a defence?
- The ability to automatically camouflage without conscious control
- The ability to change colour automatically in response to background
- The ability to produce toxic chemicals automatically when touched
- The ability to voluntarily shed a body part β like a tail β to escape a predator, which then regrows
18. Migration is a behavioural adaptation. What triggers the migration of wildebeest across the Serengeti?
- Magnetic navigation from birth location
- The movement of rival herds they must follow
- The rising of a specific constellation in the night sky
- The smell of rain and the resulting fresh grass growth
19. Which adaptation allows the migratory monarch butterfly to travel 5,000 km from Canada to Mexico?
- Both B and C β monarchs use both sun compass and magnetic navigation
- Exceptional flying speed that allows rapid travel
- Magnetic sense that detects Earth's magnetic field
- Sun compass navigation combined with a time-compensated internal clock, using the sun's position to navigate
20. What is 'thermoregulation' and how do different animals achieve it?
- A process by which animals lower their core temperature in summer
- Controlling body temperature β endotherms (warm-blooded) generate internal heat; ectotherms (cold-blooded) rely on external heat sources
- The ability to change body colour to regulate temperature
- The ability to survive in both hot and cold environments without any special adaptations
