the process of change by which an organism or species becomes better suited to its enviroment
whale -These adaptations enable a baleen whale to conserve oxygen while underwater. Baleen whales, like other mammals, have a slower heart rate while diving. When diving, blood is shunted away from tissues tolerant of low oxygen levels toward theheart, lungs, and brain, where oxygen is needed most.
polar bear -small ear ,strong legs for swimming and running ,thick layer of blubber fats ,thick layers of white fur
kangaroo - Kangaroos from these areas have behavioural andstructural adaptations that enable them to survive the harsh conditions. Kangaroos from desert and semi-arid environments have adapted to drier conditions and have several features that help them deal with the lack of water.
herbivorus mammals -Herbivore adaptations to plant defense have been likened to "offensive traits" and consist of those traits that allow for increased feeding and use of a host. Plants, on the other hand, protect their resources for use in growth and reproduction, by limiting the ability of herbivores to eat them.
