$100 Question from H1 When two organisms compete for the same resources.

$100 Answer from H1 Competition

$200 Question from H1 Includes all the resources an organism uses, including Trophic level, Habitat, Behaviors, and its role in the ecosystem.

$200 Answer from H1 Niche

$300 Question from H1 When one organism kills and eats another.

$300 Answer from H1 Predation

$400 Question from H1 When evolution of the phenotype of one species is triggered or influenced by another species. Example: Flower shape fits mouthparts of pollinator (ex. Bee)

$400 Answer from H1 Co-evolution

$500 Question from H1 Adaptation where the physical appearance of an organism blends in with the external environment in order to escape predators.

$500 Answer from H1 Camouflage

$100 Question from H2 A close and long-term interaction between members of two different living species

$100 Answer from H2 Symbiosis

$200 Question from H2 Relationship where one species benefits (+) by feeding upon another living host species. Host may be weakened over time and eventual die (-).

$200 Answer from H2 Parasitism

$300 Question from H2 Relationship where one organism benefits (+) and the other organism is unaffected (Ø).

$300 Answer from H2 Commensalism

$400 Question from H2 Relationship where both organisms benefit from the interaction (+/+).

$400 Answer from H2 Mutualism

$500 Question from H2 A barnacle on a whale or a bird nesting in a tree are two examples of this type of symbiotic relationship.

$500 Answer from H2 Commensalism

$100 Question from H3 Different phenotypes for a trait found within a population are called: V______________________

$100 Answer from H3 Variations

$200 Question from H3 Phenotypic difference that allows these organism to survive and reproduce more successfully than those with other phenotypes.

$200 Answer from H3 Adaptation or adaptive variation

$300 Question from H3 A variation that is “neutral” to an organism’s ability to successfully reproduce.

$300 Answer from H3 Non-adaptive variation

$400 Question from H3 An organism has dark spotted fur which enables it to hide and escape from predators. Which type of variation? Adaptive or non-adaptive

$400 Answer from H3 Adaptive

$500 Question from H3 Can a non-adaptive variation become adaptive? If so, how? If not, why not?

$500 Answer from H3 Yes, if the environment changes and this variation now helps the organism survive and reproduce better than others.

$100 Question from H4 What type of selection occurs when the NATURAL environment influences which variations are able to survive and reproduce. As a result future generations show an increased frequency of that trait in the population.

$100 Answer from H4 Natural Selection

$200 Question from H4 Who directs Artificial selection, and who benefits?

$200 Answer from H4 Humans: Achieved by crossing plant or animal species and selecting for traits useful to people!

$300 Question from H4 What pattern of selection?

$300 Answer from H4 Directional

$400 Question from H4 What pattern of selection?

$400 Answer from H4 Stabilizing selection

$500 Question from H4 What type of selection?

$500 Answer from H4 Disruptive selection

$100 Question from H5 The change in gene frequency in a population over time.

$100 Answer from H5 Evolution

$200 Question from H5 Organisms that interbreed and produce fertile offspring in nature.

$200 Answer from H5 Species

$300 Question from H5 Where would you expect to find fossils of the oldest organisms? A B C D E

$300 Answer from H5 E, the deepest rock layer.

$400 Question from H5 Structures that have no function in modern organisms, but were likely functional in their ancient ancestors.

$400 Answer from H5 Vestigial organs

$500 Question from H5 DNA or Amino acid comparisons show how long ago organisms shared a common ancestor (how closely related they are)

$500 Answer from H5 Molecular or Biochemical evidence

Final Jeopardy 4 steps of Natural Selection

Final Jeopardy Answer 1.Variation in the population 2. Competition for limited resources, environment selects for the best adapted 3.Differential reproduction (some survive and reproduce more than others) 4.Result: 4.Result: change in gene frequency in the population over time (evolution)
