sea horses camoflouge to its environment
Regulation example
jack rabbits regulate blow flow through vessels in ears to help regulate body temperature
Response to the environment example

Growth and development example
inherited information carried by genes controls the pattern of growth and development of organisms
Energy processing examples
Butterfly gets fuel from nectar and uses this chemical energy to do work
how does mass extinction drive evolution
species fill in new ecological gaps/niches which allow them to move up the food chain
adaptive radiation
When species can branch off and speciate in order to fill these ecological niches that open up because of mass extinction
Multicellular organisms (eukaryotes)
Cooperation between single cells
Cells within aggregates begin to express their genetic information differently giving rise to distinct tissue types
what is the cambrian explosion an example of
example of coevolution
what did the tetrapods have to deal with when they were first on land
dehydration prevention adaptations because of water loss
-vasculaization
-changes in eggs (amniotic)
-seed dispersal
