  1. 1True or False: separation of a species or population so that they no longer interbreed and evolve into two separate species is called "speciation"
    1. AVerdadero
    2. BFalso
  2. 2True or False: "Speciation" is when one species divides or gives rise to a new species
    1. AVerdadero
    2. BFalso
  3. 3Define species:
    1. Aformation of a new species
    2. Bform of reproductive isolation in which two populations are separated by geographic barriers such as rivers, mountains, or bodies of water, leading to the formation of two separate subspecies
    3. Cform of reproductive isolation in which two populations develop differences in courtship rituals or other behaviors that prevent them from breeding
    4. Da group of similar organisms that can breed and produce fertile offspring
  4. 4What does the diagram represent?Imagen de la pregunta 4
    1. AReproductive isolation
    2. BBehavioral isolation
    3. CTemporal isolation
    4. DGeographic isolation
  5. 5What kind of isolation is being shown? Imagen de la pregunta 5
    1. ABehavioral
    2. BGeographic
    3. CTemporal
  6. 6What geographic barrier separates the two populations of squirrels?Imagen de la pregunta 6
    1. ARio Grande
    2. BGrand Canyon
    3. CGila River
    4. DLake Mead
    5. EColorado River
    6. FLake Powell
  7. 7According to the hypothesis: "How might the founder effect and natural selection have produced reproductive isolation that could have led to speciation among Galápagos finches?", speciation in Galápagos finches occurred by:
    1. AFounding of a new population
    2. BGeographic isolation
    3. CChanges in the new population's gene pool
    4. DBehavioral isolation
    5. EEcological competition
    6. FTemporal isolation
  8. 8Because of what effect could the allele frequencies of this founding finch population differ from the frequencies of the original South American population?Imagen de la pregunta 8
    1. AFounder effect
    2. BBottleneck effect
    3. CGenetic Drift
  9. 9What image represents geographic isolation? Imagen de la pregunta 9
