What statement is correct about embryology?
9

• Only one vertebrate species has tails and gill
  slits at some point in its early development
• Scientists can use embryos to shows if species
  were in existence before dinosaurs
• Similarities in embryos of different species
  suggest a common ancestor
• Embryology is the study of reproductive methods
  in organisms

11
What is an incorrect statement about vestigial
organs?
10

• Vestigial organs are adaptations that allow
  organisms to survive in their environment
• The human appendix and the snakes pelvis are
  examples of vestigial organs
• Vestigial organs are structures that were once
  useful to the species ancestor but no longer
  serve a useful function
• Vestigial structures show common relationships
  with ancestral species

12
Which statement best describes Charles Darwins
theory of evolution by natural selection?
11

• Animal populations change in appearance mostly
  due to favorable mutations in DNA
• Species change whenever individuals in the
  population adapt to their environment
• Most species in nature change when humans select
  which individuals to breed
• Species that have favorable traits live longer
  and pass those traits on to offspring

Convergent evolution leads to
22

• Homologous structures that have different origins
  but similar functions
• Analogous structures that have different origins
  but similar functions
• Homologous structures with common origins that
  are modified for different environments
• Analogous structures with common origins that are
  modified for different environments

24
Which is not true about fossil evidence?
23

• Nitrogen-dating gives the absolute age of a
  fossil
• Fossils found in geologic columns of sedimentary
  rock give a relative age
• Fossils can be imprints, molds, bones, or whole
  organisms
• Fossils allow scientists to determine relatedness
  by comparing structures and anatomy of different
  organisms

25
Which statement is not correct about divergent
evolution?
24

• It results in homologous structures
• It can result in adaptive radiation
• It leads to speciation one species becoming
  many due to new adaptations in different
  environments
• It can be illustrated as

26
Which of the statements does not accurately
describe natural selection
25

• Humans select organisms with desirable traits to
  interbreed and pass those traits to the next
  generation
• Organisms that are best adapted for their
  environment live longer and produce more
  offspring
• Organisms which have certain traits that help
  them survive are more likely to pass those traits
  onto their offspring
• It is when nature selects traits that will most
  help an organism survive and reproduce in its
  environment
