what are the four requirements for evolution
variation
inheritance
selection
time
(VIST)
what does a phylogenetic tree show?
the evolutionary relationships between species through identifying shared physical and genetic features
what are the three domains of life?
eukarya
bacteria
archaea
explain the endosymbiosis theory
this theory explains why eukaryotes are structurally so different from prokaryotes because the mitochondria and chloroplasts in eukaryotes came from bacteria that were englufed.
what were the two types of bacteria that were engulfed in endosymbiosis? which was engulfed first?
Proteobacteria (first)
Cyanobacteria (second)
do eukaryotic or prokaryotic cells have a nuclear envelope?
eukaryotic
do eukaryotic or prokaryotic cells have a thicker membrane?
prokaryotic
do eukaryotic or prokaryotic cells have organelles bound by membranes?
eukaryotic
are eukaryotic or prokaryotic cells have the potential to be multicellular?
eukaryotic
which out of eukaryotic and prokaryotic have circular chromosomes and no nucleus?
prokaryotic
