1
Which of the following would an animal breeder use to increase the number of cows that give the most milk?
overproduction
genetic isolation
acquired characteristics
artificial selection
2
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
Yes because the traits of many species can be inferred from a single fossil
No, because fossils break apart after about 65 million years
No, because many species went extinct without leaving fossils behind
3
Endosymbiotic theory provides an explanation for eukaryotic cells. Which observation provides the strongest evidence
Mitochondria do not survive when they are removed from a eukaryotic cell
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
4
In addition to observing living organisms, Darwin studied the preserved remains of ancient organisms called.......
homologies
vestigial structures
fossils
adaptations
5
multicellular diploid (2N) phase of plant life
haploid
gymnosperms
sporophyte
gametes
6
seed leaves that give nourishment to the flowering plant embryo
phloem
ovules
fertilization
cotyledons
7
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
when the climate is stable, a stable environment decrease rate of evolution
after a mass extinction the survivors give rise to species that fill niches
8
Darwin's explanation that every species living or extinct must have descended by reproduction from preexisting species
Acclimation
Descent with modification
Evolution
Adaptation

develop different matting behaviors
reproduce at different time
become geographically seperated
interbreed
23

human effects on biodiversity
how genetic information is inherited
the age of Earth
24
A random change in a small population's allele frequency is known as
fitness
genetic drift
a gene pool
variation
25
