spread disease and parasites
Which letter best represents a producer in the community? - ANS B
Which of the following statements is accurate if we view evolution both as a pattern and a
process? - ANS ?
In a Hardy-Weinberg population with two alleles A1 and A2 that are in equilibrium, the frequency
of allele A2 is 0.1. What is the frequency of individuals with A1A1 genotype? - ANS 81
Which of the following results is the most likely outcome of increased gene flow between two
populations? - ANS decreased genetic difference between the two populations
Listed below are four types of animal behavior. Choose the letter of the word or phrase (A-D)
that is most associated with the following example. - ANS operant conditioning
The temporal fenestra in the skulls in fossils of ancestral mammals changed in shape and size
over time. These changes were most likely due to changes in the muscles that closed the jaws.
Which of the following research approaches would be most helpful for understanding the
evolutionary benefits of these changes? - ANS correlating the strength of jaw closure and
the size and hardness of potential prey
Which of the following graphs illustrates the growth over several seasons of a population of
snowshoe hares that were introduced to an appropriate habitat also inhabited by predators in
northern Canada? - ANS Curve up then waves
Which of the following types of sensory signals is brief and can work at night amongst physical
obstructions? - ANS auditory
If x indicates the earliest appearance of fossils of two closely related species, neither of which is
extinct, then their remains may be found in which of these strata? - ANS strata A and B only
Archeological, fossil, and geological data provide information on the Mayan populations and
their environment in Mexico, in the Caribbean state of Yucatán. Based on the figure, what can
you conclude about the history of land use in the southern Yucatán? - ANS As Mayan
population increased, deforestation increased, probably leading to increased soil erosion.
, In the region of the Rocky Mountains, one local variety of Ponderosa pine ( Pinus ponderosa)
predominantly occurs between 5,000 and 8,500 feet in elevation, where it can best tolerate
temperatures and precipitation. Which of the following changes in pine tree range is most likely
to result if future climate change in this region causes the temperature to increase and rainfall to
decrease? - ANS that variety will occur at higher elevations and/or higher latitudes
As temperatures rise due to global climate change, plant species' ranges in the southern
hemisphere may move further southward. Which of the following is a characteristic of plants that
would most likely allow them to avoid extinction by moving southward under climate change? -
ANS those having larger, and initially more contiguous, established populations
Which of the following biomes spans the largest annual mean precipitation range and the
narrowest annual mean temperature range? - ANS Tropical rainforest
An owner of a new restaurant wants to locate near a college campus. Her new Veggie Burger
restaurant can locate within 1 mile of campus or more cheaply 2 miles from the campus. But at
2 miles from campus, the restaurant may draw fewer customers. Which of the following
behaviors relates best to aspects of the restaurant owner's decision, weighing the cost of the
location, the distance from customers, and the profitability of the business? - ANS optimal
foraging model
Which of the following is an example of genetic variation? - ANS siblings with different eye
colors
Which of the following statements best describes the rationale for applying the principle of
maximum parsimony in constructing phylogenetic trees? - ANS B) Similarity due to common
ancestry should be more common than similarity due to convergent evolution.
Which conclusion below is best supported by the data? - ANS The effect of excluding
predators and adding food in the same experiment is greater than the sum of excluding lynx
alone plus adding food when considered individually.
As you study two closely related predatory insect species, the two-spot and the three-spot
avenger beetles, you notice that each species seeks prey at night when present in an area
where the other beetle species is absent. However, where their ranges overlap, the two-spot
avenger beetle hunts at night and the three-spot hunts in the morning. When you bring them
into the laboratory and isolate the two different species, you discover that the offspring of both
species are nocturnal. The observations above indicate that the two species most likely
demonstrate which of following ecological processes? You have discovered an example of
________. - ANS resource partitioning
Which of the following comparisons illustrates differences in phenotypes caused by the
environment? - ANS bodies of "body builders" versus "couch potatoes"
