1
Q
adaptation definition
A

2
Q
3 types of adaptations
A
- anatomical (physical)
- behavioural
- physiological (inside processes)
3
Q
anatomical adaptations examples
A
- body covering
- camouflage
- teeth
- mimicry
e.g. Marram grass - curled leaves minimise SA
- hairs on inside surface of leaves traps moist air
- stomata sunken pits

Q
behavioural adaptations examples
A
- survival behaviours
- courtship
- seasonal behaviours

- hibernation
5
Q
2 types of behavioural adaptations
A
- innate behaviour (ability is inherited through genes)
- learned behaviour ( learnt from experience or from observing other animals)
6
Q
physiological adaptations examples
A
- poison production
- antibiotic production
- water holding
7
Q
convergent evolution
A
- when unrelated species begin to share similar traits
- due to similar selection pressures
8
Q
analogous structures
A
adapted to perform the same function but have a different genetic origin
