wings or legs will develop on a fruit fly. Correct Answers
homeotic genes
________ is the process by which one species splits into two or
more species. Correct Answers speciation
_________ is an interruption of gene flow between populations
of the same species where the population is divided into
geographically isolated subpopulations Correct Answers
allopatric speciation
_________ is the chronicle of evolution over millions of years
of geologic time engraved in the order in which fossils appear in
rock strata. Correct Answers fossil record
_____________ are regions in which members of a different
species meet and mate, producing at least some hybrid offspring
Correct Answers hybrid zones
,A forest fire wipes out 96% of a population of aardvarks,
leaving only 6 individuals as survivors. What type of genetic
drift is this? Correct Answers bottleneck effect
A lamprey, a shark, a lizard, and a rabbit share all of the
following characteristics except Correct Answers Hinged jaws
A male redwing blackbird will chase predatory birds away from
his breeding territory during nesting season. Which hypothesis
best explains his behavior? Correct Answers He carries a gene
that causes fathers to protect their offspring, which increases
inclusive fitness.
A new organism has been discovered. Tests have revealed that it
is unicellular, is autotrophic, and has a cell wall that contains
peptidoglycan. Based on this evidence, It should be classified as
a(n) Correct Answers bacterium
A species may disappear from a local ecosystem but remain in
others, this loss of a single population is known as extirpation
Correct Answers true
A systematist uses modern technology to compare the relation of
two organisms by observing differences in their genetic
sequences and molecular data. What field of science is this?
Correct Answers molecular biology
A type of reproductive isolation mechanism in which the
differences in the timing of critical reproductive events prevent
members of closely related species from mating and producing
hybrid offspring. Correct Answers temporal isolation
, A uniform dispersion pattern is where individuals in a
population are spaced in an unpredictable way, without a
pattern. Correct Answers false
A______ consists of an ancestral species and all its evolutionary
descendants. Correct Answers clade
According to data on ecological footprints,____ Correct
Answers The ecological footprint of individuals in the United
States is more than twice the world average.
After seeds have sprouted, gardeners often pull up some of the
seedlings so that only a few grow to maturity. How does this
practice help produce the best yield? Correct Answers By
reducing intraspecific competition
Although many chimpanzee populations live in environments
containing oil palm nuts, members of only a few populations use
stones to crack open the nuts. The most likely explanation for
this behavioral difference between populations is that____
Correct Answers The use of stones to crack nuts has arisen and
spread through social learning in only some populations
An ecologist monitoring the number of gorillas in a wildlife
refuge over a five-year period is studying ecology at which
level? Correct Answers population
