4.2- Genetic diversity and adaptation

Question 1

what are the three types of adaptations?

Answer 1

behavioural
physiological
anatomical

Question 2

describe behavioural adaptations

Answer 2

the way an organism acts that increase its chance of survival and reproduction
- e.g. sometimes ‘play dead’ when threatened by a predator

Question 3

describe what is physiological adaptations

Answer 3

processes inside an organism’s body that increase its chance of survival
- e.g. brown bears hibernate over winter -> lower rate of metabolism -> conserve energy

Question 4

what are anatomical adaptations?

Answer 4

structural features that increase chance of survival
- e.g. whales have a thick layer of blubber to keep warm

Answer 5

Evolution is the gradual change in inherited characteristics of a species over a long time
