AOS 2 - Adaptation Examples Flashcards
A fluctuating core temperature
Physiological - Allows survival of extreme temps.
A slower metabolic rate
Physiological - Slow metabolic rate = Less heat produced = Body temp stays cooler
A lower breathing rate
Physiological - Slower breathing = less water loss = doesn’t dehydrate. Breathing hot air in cause’s dehydration.
Blood with a water content higher than the blood of other mammals
Physiological - The higher blood water content prevents dehydration - Go long times without water
Oval-shaped red blood cells that remain functional even after significant amounts of water have been lost
Structural/Physiological - Allow oxygen still to be transported around the body even when there is little blood water content
Extremely dry faeces
Physiological - Conserve water
An ability to drink large volumes of water
Behavioural/Physiological/Structural - Can go fro long periods of time without water
Lying down for long periods during the day
Behavioural - Conserve energy and therefore not become even hotter
Urinating so that the urine runs down its legs.
Behavioural - Allows for evaporation to cool itself down.
Squatting close to other animals
Behavioural
- Keep Warm at night
- Reduces surface area to keep cool during day
Moving during the day so that it is always facing directly at the sun
Behavioural - Less surface area exposed to the sun
A large roundish body with fat concentrated in the hump and extremely thin legs
Structural - The hump allows for storage of fat for energy, as well as an insulator.
Countercurrent exchange system
Physiological - Maintains the correct blood temp.
Elevation of their leaves slightly above the hot sand
- Not touching hot sand
- Conserves water - less transpiration
Thick dense root fibres
Allow for great absorption of water. Also allows for roots to absorb the water in the air.
