While there are many criteria to describe the difference between two species, the biological definition of a species is based on being part of: A. a population of animals living in one place B. a group of animals that behave similarly C. an interbreeding population of animals D. a population of animals capable of hybridizing E. animals that looks alike

Think about the ways we define/identify a species. What would the least precise way to determine a living species (so not extinct)? O groups of organisms that look alike O groups of organisms that are geographically separated for a significant period of time such that they become distinct genetically separate populations with different genetic markers groups of potentially interbreeding populations with are reproductively isolated from others
Which of the following is NOT a limitation of the current biological species concept? O Some scientists say that we should use DNA similarities to determine species. O It is difficult to apply to asexually reproducing organisms. O It is difficult to apply to species that are extinct. Some organisms can breed in captivity but would not breed in nature. Some organisms are obviously separate species but are sometimes able to mate and
There are a lot of pros and cons to using the biological concept. It is only one out of several types of concepts used to define a species. What would be the main criterion used for determining / differentiating between species? gene flow O niche differences O geographical isolation
Which statement about the relationship between phenotypic and genetic attributes is correct? O a Usually phenotypically similar organisms are not genetically similar. O b Organisms with very similar morphology also have very similar genes. Genetically similar organisms can appear profoundly different morphologically. O d Analogous qualities among two species are similar due to shared ancestry.
A scientist is studying two different species of fish. The table below shows various observa- tions that the scientist could have seen in the two different species of fish. Observation Number A B с 1 D 2 3 4 observation 1 observation 2 observation 3 Genetic Similarity observation 4 high low low high Function of Structure different same Which observation number would best support the claim that the two species have structural similarities, specifically as a result of convergent evolution? different same Form of Structure same different same different
f you determine that 2 similar organisms are unable to interbreed, and you therefore classify each as a different species, which species concept are you using? The ecological species concept The morphological species concept The phylogenetic species concept The biological species concept
Bird guides once listed the Myrtle warbler and Audubon's warbler as distinct species, but applying the biological species concept, recent books show them as eastern and western forms of a single species, the yellow-rumped warbler. Experts must have found that the two kinds of warblers: Question 10 options: live in the same area. successfully interbreed in nature. look enough alike to be considered one species. are reproductively isolated from each other. are allopatric.
When taxonomists recognize subspecies, they are identifying: populations with restricted enough gene flow to develop some population-specific traits, but that can still interbreed with members of other such populations. None of the other answer options is correct. populations that are reproductively isolated from one another. populations with extremely restricted gene flow due to allopatric isolation. O populations that will inevitably become separate species as reproductive isolation is nearly complete.
For which of these groups is the biological species concept not useful for determining species? Mark all that apply. O Separate recognized species that form hybrids (many plant species) Nonsexual groups Extinct groups (fossils) O Species with many remote, isolated populations (vernal pools) O Two sympatric species that do not form hybrids O An introduced species that forms a hydrid with a native species
Which of the statements are true regarding hybridization? Select all that apply. Hybridization involves the transfer of genetic material between members of similar species. Natural selection sometimes acts against progeny that result from hybridization. Hybridization occurs in plants more often than in animals. Hybridization can result in fertile offspring. Hybridization cannot result in the formation of new species.
n which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive data
