Final Exam Jeopardy Day 2
Theory of Evolution
100- Who came up with the modern theory of evolution?
Charles Darwin
200- According to the theory of evolution organisms pass on desirable traits in a process called
Natural selection
300- Where did Darwin make a majority of his observations that lead to his theory?
Galapagos Islands
400- What is the difference between artificial and natural selection?
Artificial humans select desirable traits, natural best suited weurvive and pass on traits.
500- Which scientist did Darwin build his theory from that believed acquired characteristics are
passed on to offspring?
Lamarck
Evidence of Evolution
100- What is a homologous body structure?
Structure that differ in adult form but had same embryonic tissue
200- How do embryos show evidence of evolution?
Most animals look very similar in the early embryonic stages
300- How are fossils used as evidence of evolution?
Show extinction of species and intermediate forms of species
400- What is a vestigial structure?
An organ that is so reduced in size it only resembles organs of other species
500- How does a protein such as Cytochrome C show evidence of evolution?
When many different species have the same complex protein it means that they must be
connected in some way, they share a common ancestor.
Genetic Variation & Patterns
100- What is a gene pool?
All the genes in a population
200- What is genetic drift?
Random changes in allele frequencies of a population
300- What is an example to directional natural selection?
Finches with larger thicker beaks in areas with large seeds.
400- When will disruptive selection occur in a population?
When individuals at either end of the bell curve have higher fitness then those in
the middle.
500- What are 3 of the 5 factors that are needed for evolution not to occur according to the
Hardy-Weinberg Theory?
Random mating, large population size, no mutations, no migration, and no natural
selection.
Ecology
100- An organism that eats meat and plants is called
Omnivore
200- Put the following terms in order: population, species, biome, community, biosphere
Species, population, community, biome, biosphere
300- An organism that only eats dead matter is known as
Detritivore
400- Give an example of a commensalism relationship
Barnacles on a whale
500- Why do food chains usually have no more then 4 trophic levels?
With each trophic level a large portion of energy is lost
Potpourri
100- What was the name of the ship Darwin traveled on?
H.M.S. Beagle
200- What is a mutation?
Random change to genetic code
300- What is the difference between an abiotic and a biotic factor?
Abiotic is non-living, biotic is living
400- What is gene shuffling?
When gametes form the chromosomes separate and provide variation
500- What is the difference between an X-linked trait and an autosomal trait?
X-linked is carried on the sex cell and autosomal is on a non-sex cell
