Unit 3 Test Review (multiple choice test)
CST – Computer Scored Test
1. Graph Interpretation
-population of a species with compared to without a predator present
2. Evidence for Evolution
-see list from Jeopardy activity
-Fossils = for evidence of evolutionary change over time
-Genome (genetic code) = for identifying a common ancestor
3. Cladogram Interpretation
-chart showing characteristics of several species
-compared to existing cladogram to find accuracy of species placement
4. Rate of Speciation
-“high” means quicker change from one species to another over time
(graph interpretation)
5. RNA in Evolution
-1st self-replicating living molecule
-RNA binds with other molecules to carry out chemical reactions
6. The Miller-Urey Experiment
-designed to prove that under the right conditions, organic molecules can
be produced in nature
-not as valid today because some of the atmospheric gases were not
necessarily present
-the key is that fatty acid molecules can form vesicles (bubbles) in pools
(water) on earth’s surface
7. Review of Membranes and Movement of Molecules
-Impermeable vs. Permeable vs. Selectively Permeable
-proteins that control what molecules enter and leave
8. PCR = Polymerase Chain Reaction = a technique for rapidly producing
many copies of a fragment of DNA for diagnostic or research purposes
Plasmid-based Transformation = the transfer of genetic material from a
living cell (typically animal including human or plant cells) to a bacterial
cell
TST – Teacher Scored Test (essay test)
1. How to prove evolutionary history of an existing animal type + timeline:
(15)
Morphology-dissect a variety of related species
-dissect and compare to similar species with a desired trait
-look for vestigial organs and other anatomical features
-build a phylogenetic tree
Biochemical-obtain a variety of species + similar species with a desired trait
-collect DNA and locate similar genes
-compare gene sequences
-build/refine the phylogenetic tree
Geological-search for fossil records of animal and similar species and
transitional fossils
-identify geological time periods
-arrange a timeline
-compare morphology over time
-refine and extend phylogenetic tree
2. Evolutionary Relatedness (6)
-posing scientific inquiry questions based on an existing phylogenetic tree
Phylogeny = the development or evolution of a particular group of
organisms
a. Shared characteristics
b. Biogeographical distribution
c. Morphological characteristic
3. Investigating Phylogeny (22)
-analysis of genomic data (DNA strands) to construct a phylogenetic tree
a. Describe the data analysis process
b. Show the results of your data analysis
c. Draw a phylogenetic tree
