is domain bacteria prpkayotes or eukaryotes?
prokaryotes
what domain do cell walls lack peptidogylcan?
domain arches
what kingdom do cell walls have cellulose?
Protista
which kingdom has widespread diversity including many animal like, plant like, and fungi like behaviors
Protista
what kingdom has chiton in the cell walls
fungi
does kingdom plantar have chloroplasts
yes
does kingdom animalia have cell walls and chloroplasts?
no
Linnaeus hierarchical system
kingdom phylum class order family genus species
grouping organisms into categories that represent lines of evolutionary decent not just physical similarities
phylogeny
organisms are arranged into cladograms to show relationships through evolutionary time
cladostics
how many chromosomes do chimps and humans have in common
18 pairs
how much % are humans and chimps genetically similar?
98.77%
what domain has cell walls with peptidogylcan?
domain bacteria
any change in the relative frequency of alleles in a population
evolution
some can be accedently beneficial or harmful
mutations
the ability of an organism to survive and reproduce in its environment
fitness
can beal size on birds influence food accesability?
yes
when a single animal had several hundred offspring
over production
random change in an allele frequency by chance
genetic drift
a small change in a population is called
the founder effect
what drives the population of birds o paradise?
the active choice between strong pretty makes
the process that creates a new species through isolation from others
speciation
animals having different courtship rituals or behaviors that lead to reproduction
behavioral isolation
where 2 or more populations are separated by a river mountain or body of water
geographic isolation
2 or more species reproduce at different times
temporal isolation
about how old is the earth
4.6 billion years
why was the sky pinkish
high levels of hydrogen co2 cyanamide co n2 and h2
how long ago did the earth cool
3.8 billion years ago
why were the oceans brown
high levels of dissolved iron
what did Stanley Miller and Harold eiuries expirement show
how cytosine and uracil ar made
when were the first signs of life
2.2 billion years ago

what keeps the earths core in a melted form?
radioactive decay
are the minerals that make up the crust of the earth?
less dense
what element was absent from earths atmosphere as a free molecule
oxygen
Miller and Urey were able to create these in their experiment
amino acid
this states that eukaryotes arise from from communities of prokaryotes
endosymbiotic theory
