B16.6 Adaptations And Extremophils Flashcards
What is an extremophile ?
An organisms that lives in an extreme environment
What are thermophiles?
Organisms that live in extreme temperature
How are polar bears adapted to their cold environment ?
Smalls ears which reduces surface area
Thick fur and blubber that traps heat
How are penguins adapted to their environment ?
Huddling
- shivering generates heat
- also reduces surface area
What is a structural adaptation ?
An adaptations of body shape or body structure
How is a camel adapted to its environment ?
- Hump which shifts body fat away from torso and stores energy
- Wide, flat feet
Reduces eight pushing down into the sand - Long eyelashes to keep sand out of eyes
- Wide feet which prevent it from sinking into the sand
What are behavioural adaptations ?
Adaptations to behaviour or lifestyle due to environment
What are some examples of structural adaptations ?
Thick fur- providing insulation to reduce heat loss
Wide flat feet- reduce weight pushing into sand
Furry feat- reduces heat loss from feet
What are Halophiles ?
Extreme slat
What are some examples of Halophiles ?
Some Archae bacteria can drug hide in very high salt conditions
Why is high salt dangerous ?
Normally dangerous because the solution is very Hypotonic meaning water will leave the cells causing dehydration
