-
legless condition in several groups of extant reptiles result of
several instances of legless condition arising independently
-
sceintific discipline with naming organisms
taxonomy
-
verious taxonomic levels of heirarchial classification differq
inclusiveness
-
bionomial scientific name
panthera leo
-
phylogenetic tree that is rooted is
at whose base is located the common ancestor of all taxa
-
sequence from most to least comprehensive
b k p c o f g s
-
most specific
genus musca
-
greatest degree of structural homology
D and F
(e)
-
common ancestor of two species is most analogous to which anatomical tree part
node where two twigs diverge
-
criticism of classification scheme is most likely from adherent of phylocode method of classification?
the only biologically valid classification of potato varieties is one that accuartely reflects their genetic and evolutionary relatedness
-
homoplasy
legless conditon found in various types of extant lizards
-
best exaplnation for discrepancy
common ancestry
-
best classification system is that which closely
reflects evolutionary history
-
best examples of homologous strucutres?
bat wing and human hand
-
morphological similarities of two species are due to
possession of analogous structures
-
entirely of peptidoglycan
cell wall
-
requires ATP to function, and permits some species to respond to taxes
flagellum
-
not present in bacteria, enables cell to resist defenses of host
capsule
-
enables to germinate after exposure to harsh conditions
endospore
-
-
endotoxin in gram-negative
cell wall
-
connects cytoplasm of two bacteria
sex pilus
-
copy of chromosome along with a small amount of dehydrated cytolasm within a tough wall
endospore
-
prokaryotic reproduction correct statement
mutation is a primary source of variation in prokaryote populations
-
prokaryotes
divide by binary fission, without mitosis or meiosis
-
experimental populations of cells over 8yr perid
microevolution
-
least reasonable in terms of promoting bacterial survival over evolutionary time in low-glucose enviro
increased reliance on glycolytic enzymes
-
what can be infered
the highest rate of genetic change occured during the first quarter of the experiment
-
vertical axis refers to darwinian fitness, most accurate is
number of generations per unit time
-
new variation solely spontaneous mutations most effective process
binary fision
-
what should be true of 3 colis generation time
generation time should be slower than in the typical environment
-
snail-like coiled porous test (shell of calcium carbonate
foraminiferans
-
least likely to contribute to ability of single-celled foraminiferan to grow to diameter of several centimeters
calcium carbonate test contributes to extra mass
-
what makes certain red algae appear red
they possess pigments that reflect and transmit red light
-
largest seaweeds belong to
brown algae
-
chloroplast of land plants derived to which sequence
cyanobacteria - green algae - land plants
-
chloroplasts of all derived from ancestral red algae ecept
green algae
-
marine multicellular and lives at a depth reached only by blue light
red algae
-
green algae often differ from land plants in that some green algae
are unicellular
-
which taxon of eukaryotoic organisms is thought to be directly ancestral to plant kingdom
green algae
-
archaeplastidae eventually designated a kingdom, and if the land plants are excluded what will be true
it will be paraphyletic
-
best evidence for not classifying the slime molds as fungi comes from
dna sequences
-
pair of alternatives highlighted by life cycle of cellular slime molds dictyostelium
unicellular / multicellular
-
pairs a protist with one of its characteristics
apicomplexans - parasitic
-
false about protists
primary organism that transmits malaria to humans by its bit is the tsetse fly
-
-
unicellular eukaryote has siliceous glasslike shell and autotrophic nutrition
diatoms
-
mushrooms and toadstools
basidiomycota
-
largest to smallest
mycelium, basidiocarp, gill, basidium, basidiospore
-
mushroom with gills have meioticaly produced spores located in
basidia
-
distinguishes ascospores from conidia
ascospores have undergone genetic recombination during their production, conidia have not
-
fungal movement
cytoplasmic streaming in hyphae
-
structures both penicillium and aspergillus produce asexual spores
conidiophores
-
most porbable location of oldest portion of mycelium
c
-
location nearest basidiocarps
a
-
mycelium currently absorbing the most nutrients per unit surface
a
-
lowest concentration of fungal enzymes
d
-
highest concentration of free basidiospores in an air sample
d
-
growth pattern most similar to that of mycelium produced in fairy ring
skin mycoses
-
most likely to be buried at location c
tree stump
-
chemicals secreted by soil fungi that inhibit growth of bacteria
antibiotics
-
lichens are symbiotic assocations of fungi and
- cyanobacteria and green algae
- E
-
least affiliation with all others
lichens
-
fungal strucutre that is usually associated with asexual reproduction
conidiophore
-
largest to smallest
ascomycete, ascocarp, ascus, ascospore
