Complex multicellular organisms have a genome similar in scope
and size to their single-celled predecessors. - ANSWER-false
Rarely, hybridization has occurred between polar bears and
grizzlies. The presence of hybrids that can successfully reproduce
suggests that - ANSWER-suggests that the time since divergence
may not be sufficient for complete reproductive isolation to have
occurred.
Root hairs on a root develop _____. - ANSWER-Surface area
Why do we think that male Neanderthals mated with non-African
ancestral Homo sapiens? - ANSWER-Because Neanderthal
nuclear DNA sequences are present in the human gene pool, and
Neanderthal mtDNA sequences are not.

A population that exhibits only one allele at a particular gene is
_________________ for that allele. - ANSWER-fixed
Photorespiration results in: - ANSWER-the consumption of ATP
and the loss of co2
Which of the following could be true if a plant cell is exposed to a
toxin that makes the thylakoid membrane freely permeable to
hydrogen ions? - ANSWER-There would be no ATP available to
drive carbohydrate synthesis in the Calvin cycle.
If water molecules (H2O) suddenly stopped forming hydrogen
bonds with one another, how would water transport in vascular
plants change (if at all)? - ANSWER-It would stop, as water
transport relies on H20 molecules being connected by hydrogen
bonds.
With the advent of tools to incorporate molecular data,
phylogenetic analysis can be used to: - ANSWER-reconstruct the
evolutionary history of a group of organisms over millions of
years.

B) track the spread of a pathogen, such as a fungus or virus, from
place to place.
C) identify the origin of invasive pest species.
D) track shipments of endangered species or their products (such
as elephant ivory or bushmeat).
How does the level of genetic variation in humans typically
compare to other species? - ANSWER-lower than other species
Which product(s) of the Calvin cycle is (are) exported from the
chloroplast for use by the plant cell? - ANSWER-Triose phosphate
To which superkingdom does the organism that causes amoebic
dysentery belong? - ANSWER-amoebozoa
Different species of fruit flies occupy each of the islands in the
Hawaiian island chain, a group of volcanic islands that formed
one after the other. One hypothesis for how the different fruit fly
species formed is that, after each new island was formed, fruit
, 4|Page
flies from existing islands colonized it and subsequently diverged.
If this hypothesis is correct, it would be an example of: -
ANSWER-allopatric speciation by dispersal.
Which of the following is NOT true of protists? - ANSWER-Protists
can be prokaryotes or eukaryotes.
A drawback of the biological species concept is that it cannot be
applied to: - ANSWER-asexual organisms
You have spent time working with a population of beetles. Males
range in size from 2-6 cm in length. You realize that the females
only mate with males that measure less than 3 cm long. If you
measured allele frequencies at a single locus that contributes to
overall length, would you expect this population to be in Hardy
Weinberg equilibrium from one generation to the next? -
ANSWER-no
Which of the following are produced by roots in order to increase
surface area, allowing for greater access to nutrients in the soil? -
ANSWER-root hairs
