classification test Flashcards
what is radiometric dating
uses radioactive isotopes to find the EXACT age
what is relative dating
uses layers of the earth to estimate order of appearance/disappearence in fossils
what is graduilsm (a rate of evolution)
slow, steady evolution
what is punctuated equilibrium (a rate of evolution)
long periods of genetic equiliobrium followed by rapid bursts of revolutionary change
what arre the patterns of macroevolution
divergent, convengent, adaptive radiation, coevolution
what is adaptive radiation
one species evolves into several quickly
what are the conditions of early earth
no free oxygen, extreme hot, asteroids/comets, volcanoes
what are the first compounds found
unicellular prokaryotes (anaerobic)
describe the miller and urey experiment
they recreated the conditions of early earth to test for organic compounds
what did miller and urey find
amino acids and sugar
how was the atmosphere filled
photosynthetic prokaryotes filled the atmoshpere
what kind of classificatiuon did linnaeus use
traditional classification
what was linnaeus’s system based on
anatomical similaritys and differences
what is the term linnaeus used
taxa
what is the order of taxa for classification
kingdom, phyllum, class, order, family, genus, species
what is binomial nomenclature used for
a system for naming organisms
how is the first word of a name written
capitilized in italics
what taxa is the first word
genus
what taxa is the second word
species
how is the second word written
lowercase in italics
what are derived characteristics
what traits arise before each organism
describe domain bacteria
prokaryotes, unicellular, asexual, cell wall with peptidoglycan, MOST COMMON (some helpful/some harmful)
what kingdom is bacteria
eubacteria
describe domain archea
prokaryotic, unicellular, asexual, NO peptidoglycan, LIVE IN EXTREME ENVIORMENTS
