BIOLOGY 1407 - FINAL EXAM REVIEW
QUESTIONS AND ANSWERS
What theory was Darwin the first to propose? - Correct Answers -natural selection is a
mechanism for evolution
Which of the following MUST exist in a population before natural selection can act upon
that population ? - Correct Answers -genetic variation among individuals
The role that humans play in artificial selection is to ... - Correct Answers -choose which
organisms reproduce
Of the following anatomical structure, which is homologous to the bones in the wing of a
bird ? - Correct Answers -bones in the flipper of a whale
What must be true of any organ described as vestigial ? - Correct Answers -it must be
homologous to some feature in an ancestor
Structures as different as human arms, bat wings, and dolphin flippers contain many of
the same bones, which develop from similar embryonic tissues. These structural
similarities are an example of _____. - Correct Answers -homology due to divergent
evolution
Which of the following evidence most strongly supports the common origin of all life on
Earth ? All organisms _____ - Correct Answers -use essentially the same genetic code
Three populations of crickets look very similar, but the males have courtship songs that
sound different. What function would this difference in song likely serve if the
populations came in contact? - Correct Answers -a behavioral reproductive isolating
mechanism
Where is the pelagic realm ? - Correct Answers -the sea
The production of sterile mules by interbreeding between female horses (mares) and
male donkeys (jacks) is an example of _____. - Correct Answers -reduced hybrid fertility
Light clams (that resemble stones) and dark clams (that resemble shadows) are both
less likely to be spotted and eaten by predators than their gray (intermediate)
counterparts. What type of selection does this display? - Correct Answers -disruptive
selection
, ______ is the complete loss of a species in one area - Correct Answers -extirpation
What is an example of a protected area ? - Correct Answers -nature reserve
Which trophic level gains the most energy ? - Correct Answers -producers
A symbiotic relationship in which both species benefit from one another is known as
________ - Correct Answers -mutualism
A decreased response to a stimulus over time is know as _________ - Correct Answers
-habitualism
Which is an inmate behavior ? - Correct Answers -fixed action pattern
What typically gives a population a "carrying capacity" ? - Correct Answers -limiting
factors
What is the most rapid cause of the loss of biodiversity ? - Correct Answers -habitat loss
_________ turns ammonia (NH4+) into nitrite (NO2-) and then nitrate (NO3-) - Correct
Answers -nitrification

- Correct Answers -hinged jaw
Which of following groupings includes the largest numbers of species ? - Correct
Answers -invertebrates
Which of the following animal groups does not have tissues derived from mesoderm ? -
Correct Answers –cnidarians
What are the members of the SAR supergroup, and what clade are they in? - Correct
Answers -Stramenopiles, Alveolates, and Rhizarians clade Harosa
Which prokaryotes are pathogenic? Which are not? - Correct Answers -Pathogenic
(disease causing): streptococcus and staphylococcus, Non-pathogenic: lactobacillus
and Escherichia coli.
What does an endospore do? - Correct Answers -Allows the bacterium to produce a
dormant and highly resistant cell to preserve the cell's genetic material in times of
extreme stress.
