all about adaptations
Show Answers:

  1. How is a koala bear adapted to survive in an eucalyptus forest?
    They can eucalyptus leaves that are very poisonous to other animals. therefore they have a good supply of food and are more likely to survive.
  2. How does binocular vision help a bear catch a fish?
    Binocular vision helps the bear have a better judgement of distance and size.
  3. A polar bear is adapted to what kind of environment?
    The Arctic
  4. Why can some plants survive in extreme colds without freezing?
    They have antifreeze proteins in their cells
  5. Why don't penguins lose body heat through their flippers?
    They have a counter-current heat exchange. Warm blood entering the flippers flows past cold blood leaving. This warms the leaving blood and cools the entering blood, reducing heat loss.
  6. Suggest how a wasp is adapted to avoid being eaten
    They don't fly away but stand up to predators, their warning colouration tells them they can sting so predators back down.
  7. How does the pattern of zebras help them with predators?
    Predators such as lions, when they attack, are unable to tell where one zebra ends and another begins so are partially confused.
  8. Why would a lizard not survive in a cold environment?
    Reptile cannot regulate their body temperatures like mammals can. They need to warm up in the sun and cool off in the shade.

    • Migration
    • Curling up
