Adap And Varations Flashcards
What is it like in the desert
Extreme heat in day
Extreme cold at night
Minimal water and vegetation
What is it like in deep ocean
No light= minimal vegetation
Extreme cold temperatures and pressures
What is it like in Antarctica
Coldest place- -10 to -60
Minimal vegetation
Freezing waters
What does selection pressures means
Factors that contribute to selection which variation will provide individual with increase chance of surviving over others
Linked to event such as natural disaster or introduction of new species
Give an example of stabilising pressure
Tall plants are exposed to wind
Short don’t get enough sunlight
Middle are more likely to be passed down
Give example of directional
Deer species have green body
New predator
Deer has new colour which allows to be camouflaged
Give example of diversifying
Small birds hide in holes
Middle are most at risk
Big less likely to be attacked
