SCRIPT VERIFIED QUESTIONS AND
SOLUTIONS GRADED APLUS
●● natural selection
Answer: A process in which individuals that have certain inherited traits
tend to survive and reproduce at higher rates than other individuals
because of those traits.
●● diversity
Answer: all of the different species on Earth
●● gene variation
Answer: the different alleles within a single species
●● species
Answer: group of similar organisms capable of interbreeding and
producing fertile offspring
●● common ancestry
Answer: a group of organisms share common descent (have similar
traits) if they have a common ancestor
, ●● fossil record
Answer: the geological record of organisms on earth that have been
preserved in the rock in a chronological order (oldest on bottom);
evidence of common ancestry
●● Definition of homologous structures
Answer: structures that have the same structure but function differently;
limbs
●● Definition of analogous structures
Answer: structures that have different structure but function similarly;
no common ancestry
●● Definition of vestigial structures
Answer: a structure that an organism has that is no longer useful to it,
but that they have this structure because a common ancestor to that
organism found it useful
●● fitness
Answer: ability of an organism to survive and reproduce in its
environment
●● gene pool
Answer: The collection of all the genes in a population
