4. Which of the following is not one of the
conditions required for natural selection?
A.
B.
C.
D.
Variability for a trait
Trait must be heritable
Trait must be genetically dominant
Trait must lead to differential reproduction
While natural selection only acts upon
expressed traits (acts upon phenotype),
both dominant and recessive traits face
natural selection pressure. Recessive traits
face natural selection pressure on
individuals that are homozygous recessive
(express the recessive trait).
It is true that because the recessive allele
can be “hidden”, harmful traits still present
in the gene pool are more likely to be
recessive.
5. Which of the following is a limit to
adaptation?
A. Favorable trait must exist in the gene pool.
B. Having a high reproductive rate.
C. Mutations that lead to an adaptation cannot
be random.
D. Adaptations that are compromises lead to
extinction.
6. Natural selection which eliminates individuals
at both ends of the spectrum of variation is called
A.
B.
C.
D.
Directional selection.
Stabilizing selection
Diversifying selection.
Bimodal selection.
If natural selection pressure favors the average,
and acts against BOTH extremes the distribution
will narrow. Stabilizing Selection.
7. If natural selection favors one extreme of the
distribution, and acts against the other it is called
A.Stabilizing Selection
B.Disruptive or Diversifying Selection
C. Directional Selection
D. Genetic Drift
8. Interactions between two species that
result in ongoing evolutionary changes in
each species is called
A.
B.
C.
D.
Convergent evolution.
Coevolution.
Directional evolution.
Symbiotic evolution.
9. Which of the following is an example of
convergent evolution?
A. Flowers evolving colors and fragrances that attract
bees.
B. Giraffes evolving longer necks to reach higher
branches.
C. A newt species adapts to have high to have high
levels of toxin while a garter snake that preys upon it
adapts to be able to tolerate a high level of toxin.
D. Whales and fish having streamlined shapes.
In convergent evolution, trait is not shared by more closely
related species. The trait evolved independently in more
distantly related species because the of similarities in natural
selection pressure.
10. Which of the following would most
likely lead to speciation?
A.
B.
C.
D.
Geographic isolation.
Coevolution.
Stabilizing natural selection.
A mutualistic relationship.
11. A shift in a gene pool (a change in the
frequency of gene/how common a gene is) that is
do to random chance ….

C. is called adaptation
D. gene pools cannot change due to random
chance
12. Genetic drift is more likely to occur ___
A. in a species with a high reproduction rate
B. in a species with a slow reproduction rate
C. in a large population
D. in a small population
13. When two species that compete over a food source
or habitat adapt over time to utilize the resource in a
way that reduces/avoids direct competition it is called
A. Competitive exclusion
B. Interference competition
C. Resilience
D.Resource petitioning
14. Which of the following would most likely
cause an adaptive radiation to occur?
A.
B.
C.
D.
The introduction of an invasive species.
A mass extinction event.
Human population growth.
Long-term stability in the climate.
15. Which of the following is not part of
the niche of a species?
A. What trophic level it is (step on the food
chain)
B. The nutrient requirements of the species
C. The range of temperature the species can
tolerate
D. The potential medical benefits of the species.
16. Specialist species have a _______ and
have and advantage in a _______________.
A. broad niche; stable environment
B. narrow niche; stable environment
C. broad niche; rapidly changing environment
D. narrow niche; rapidly changing environment
17. Endemic species are:
A. species that serve as early warnings that a
community or ecosystem is being damaged.
B. species that play a critical role in an
ecosystem.
C. a type of native species found nowhere else
on earth.
D. species that spread disease.
18. Exploitation competition occurs when:
A. There is an overlap of niches.
B. One species limits another species’ access to
a resource.
C. One species uses a resource more efficiently
than another.
D. Seniors cheat to win spirit competitions.
19. Typical trends in succession is for diversity
to __________with time, and for plant size to
___________with time.
A. decrease, decrease
B. decrease, increase
C. Increase, increase
D. Increase, decrease
20. The trees in a mature/climax community in a
temperate deciduous forest biome ______________
than trees earlier in the process of succession.
A. are faster growing
B. have higher light requirements
C. are better competitors
D. both A and C
21. Inertia (or persistence) is the ability of
a ecosystem to :
A. recover after a disturbance.
B. survive minor ecological disturbances
C. develop into a mature/climax community
D. to expand it’s range.
22. Rainforests have a high level of biodiversity, but
have very poor soil (because the conditions for life
are so ideal that those nutrients get used up quickly
and are stored in the large amount of biomass in a
rainforest). Rainforests have ...
A.High inertia/persistence and low resilience
B.Low inertia/persistence and high resilience
C.Both low inertia/ persistence and low resilience
D.Both high inertia/ persistence and high resilience
The high biodiversity creates many available niches- so that a
rainforest has more inertia to withstand minor ecological
disruptions.
However, with very poor soil, a rainforest is not resilient and
generally can not rebound well from major ecological
disruptions.
23. The top two causes of loss of biodiversity are
A.
B.
C.
D.
Habitat loss and pollution.
Habitat loss and invasive species.
Invasive species and pollution.
Hippos and elephants.

new environments.

of an extinction-prone species:
A. Low on the food chain
B. Low reproductive rate
C. Specialist
D. Endemic
26. What is the primary reason top consumers
more vulnerable to extinction?
A. Because they are usually prized for their furs.
B. Because they compete directly with humans for food.
