1
Temporal isolation occurs when two different populations
develop different matting behaviors
reproduce at different time
interbreed
become geographically seperated
2
Darwin's explanation that every species living or extinct must have descended by reproduction from preexisting species
Evolution
Acclimation
Adaptation
Descent with modification
3
Glyptodont fossils & living armadillos, Darwin observed during his voyage are related to which pattern of biodiversity?
all the above
species vary locally
species vary over time
species vary globally
4
When is adaptive radiation most likely to occur, and for what reason?
before a mass extinction, species are competing intensely for resources
when the climate is warmest
after a mass extinction the survivors give rise to species that fill niches
when the climate is stable, a stable environment decrease rate of evolution
5
hollow tube-like water conducting cells with thick walls strengthened by lignin
diploid
phloem
hyphae
tracheid
6
growth of the embryo in response to timing, temperature, and moisture cues in the environment
cotyledons
germination
dormancy
pollination
7
The birds Darwin collected from the Galapagos Islands were all Sparrows
True
False
8
A random change in a small population's allele frequency is known as
variation
a gene pool
genetic drift
fitness
9
plant embryo + food supply + protective covering
xylem
vascular tissue
pollen
seed
10
multicellular diploid (2N) phase of plant life
gymnosperms
gametes
sporophyte
haploid
11
A "Switch" is a part of the DNA that does not code for any protein but rather turns on and off production on them.
False
True
12
According to Malthus, what would occur if the human population grew unchecked?
evolution of a new specues
extinction of humans
development of new traits in humans
disease, war, or famine
13
Each "tick" of a molecular clock is an occurrence of
crossing-over
DNA mutations
mitossis
genetic drift
14
In addition to observing living organisms, Darwin studied the preserved remains of ancient organisms called.......
vestigial structures
homologies
adaptations
fossils
15
The wing of a bat and the wing of a bee or another insect are examples of what type of structures?
analogous structures
unrelated structures
vestigial structures
homologous structures
16
Who is right?
B
A
C
17
Which property describes members of kingdom Animalia, but not the members of the kingdom Plantae?
cell walls made of chitin
autotrophic
heterotrophic
cell walls made of cellulose
18
Do fossils provide a complete record of all the extinct species that lived on Earth? Why or why not?
Yes, because all species left fossils behind
No, because many species went extinct without leaving fossils behind
Yes because the traits of many species can be inferred from a single fossil
No, because fossils break apart after about 65 million years
19
seed leaves that give nourishment to the flowering plant embryo
ovules
phloem
fertilization
cotyledons
20
What are the two types of vascular tissue found in plants?
Vascular and Nonvascular
Vascular Tissue
Xylem and Phloem
Green Algae
21
vascular plants that reproduce using spores
angiosperms
gymnosperms
bryophytes
tracheophytes
22
Endosymbiotic theory provides an explanation for eukaryotic cells. Which observation provides the strongest evidence
Bacteria and algae have been observed to live inside eukaryotic cells
Chloroplasts are found in plant cells, but not animal cells
The cell membranes of prokaryotes and eukaryotes have a similar structure
Mitochondria do not survive when they are removed from a eukaryotic cell
23
Which of the following would an animal breeder use to increase the number of cows that give the most milk?
genetic isolation
overproduction
acquired characteristics
artificial selection
24
Belief that life is too complex to have evolved through natural processes & that an outside possibly divine force must
Creation science
Creationism
Darwinian evolution
Intelligent design
25
Darwin’s theory of evolution offers a scientific explanation for which of the following?
human effects on biodiversity
changes in species over time
the age of Earth
how genetic information is inherited
