reptiles do not, what is
the best explanation as to why birds are
more closely associated with reptiles?
A. Other vestigial structures place birds in a close
relationship with reptiles.
B. Phylogenetic trees show importance to external, rather than
internal, similarities.
C, The heart is a homologous structure that is not used to
determine phylogenetic relationships.
D. The heart must be an analogous structure that has evolved
twice.
2. Which of the following is true about genetic variation
in a population?
A> Differences between populations of the same species
increases with a reduction of genetic variation.
B. Differences between populations of the same species decreases
with a reduction of genetic variation.
C. Random processes in evolution have no effect on genetic
variation.
D.Random processes in evolution only have an effect on genetic
variation for populations of different species.
3.When scientists replace a gene (DNA) from one species with the
same gene (DNA) from a different species, the same amino acids will
be produced. This happens because
A. all organisms have nucleic acids, so they all produce amino
acids
B. all organisms have DNA, so they produce the same biological
molecules
C. organisms use DNA to replicate, and RNA to store the genetic
information
D. all organisms share a common ancestor, so their genetic code
is universal
