1. ADAPT and SURVIVE

2. The Camel
Can store a lot of water and a thirsty camel can drink 100 litres of water in 10 minutes.
Tolerant to big changes in body temperature to remove need for sweating and thus reduce water loss
Further reduces water loss by producing minimal volumes of urine
Each two-toed foot spreads on the ground, spreading the load and stopping the camel sinking into soft sand
All fat is stored in the hump, there is no layer of body fat. This helps it to lose body heat.

3. The Camel
The hump shrinks when the camel uses it for food. Because of this fat store, a camel can go for 1-2 weeks without food
Large body surface area to maximise loss of body heat
Ears are fur-lined which helps to keep out sand
Their nostrils can close to keep out sand. Twitching their nose helps to cool the incoming air
They have 34 sharp teeth and a hard mouth lining for eating prickly thorn bushes

4. The Camel
Camels have bushy eyelashes and a layer of skin under the eyelid that helps to protect their eyes
Leathery patches of skin on the knees and chest prevent camels from getting burnt when lying on hot sand
Sandy colour blends into surroundings to give good camouflage

5. The Cactus
Leaves have evolved into small spines to reduce water loss through evaporation
Small surface area compared to its’ size (1000 x less than normal plants) which also reduces water loss
Stems and spines have a waxy layer to reduce water loss
Swollen stem in which to store water in order to survive dry conditions
Spines stop herbivores eating them

6. The Cactus
Cacti use their stems to produce food by photosynthesis. The stems of cacti therefore contain large numbers of chloroplasts
Shallow but very extensive roots ensure water is absorbed quickly over a large area when it rains
Some cacti have very long roots to reach water stored far beneath the surface

7. The Polar Bear
Large size and compact shape (i.e rounded), including small ears to keep surface area to a minimum reduces heat loss
Thick layer of blubber for insulation and to survive hard times when food is scarce
Thick hairy coat – snow slips off stiff outer hairs. Fine woolly hairs under them trap warm air which is a good insulator

8. The Polar Bear
Greasy fur which sheds water after swimming to prevent cooling due to evaporation
White fur to match surroundings for camouflage
Strong swimmer to catch food in the water and strong runner to run down prey on land
They can paddle in water with front legs and steer with back legs

9. The Polar Bear
Large feet with hairy soles which both insulate and grip (spread the weight on the snow and ice)
Small ears and eyes to conserve heat
Good sense of smell for hunting
Long pointed nose warms cold air on its way to the lungs
