    1. AVerdadero
    2. BFalso
33. 33Examples of Antarctic animal adaptation are: salty blood (stops them freezing in water), slow growth, low metabolic rate (low energy use), blood at low temperature so holds more oxygen, more oxygen means more growth, a layer of fat (blubber), super cooling to lower body temperature to freezing point.
