- 1. Multiple Choice
The forelimbs of a whale, human, and bat all have similar bone structures therefor are examples of...
analagous structures
vestigial structures
homologous structures
convergent structures
- 2. Multiple Choice
A snake has tiny hip bones where legs could attach, the bones have no function. How do the bones support evolution of snakes?
the hip bones are vestigial structures that show evolutionary descendant from an ancestor
the hip bones are analogous structure
the hip bones are vestigial structures that show that snakes, worms and other legless animals evolved together
the hip bones are homologous structures
- 3. Multiple Choice
How do mass extinctions affect the rate of evolutionary change?
organisms that survive mass extinctions evolve more rapidly because they face limited competition.
organisms evolve slowly after mass extinctions
organisms do not evolve after mass extinctions
evolutionary change occurs slowly after mass extinctions because a large number of species have become extinct over a relatively short time.
- 4. Multiple Choice
How could you identify a pattern of punctuated equilibrium?
similar bone structures among species
identical genetic code among all species
fossil sequence that shows gradual changes over long time
fossil sequences that show rapid changes over short periods of time
- 5. Multiple Choice
Endosymbiotic theory explains how eukaryotic cells evolved from ancient prokaryotic cells. The theory is supported by which of the following:
mitochondria and chloroplasts have their own DNA and make some of their own proteins
like other organelles mitochondria and chloroplasts can not survive outside the cell
all multicellular organisms are eukaryotic
mitochondria and chloroplasts rely on the cytoplasm
- 6. Multiple Choice
In order for a scientist to put fossils in order of sequence, which analysis would be most useful?
measuring the width and length of the homologous bones
identify which types of minerals are in each fossil
radiometric dating, which would show the absolute age of the fossils
biogeography showing where all the species lived at one time
- 7. Multiple Choice
The early Earth's atmosphere was lacking:
Carbon Dioxide
Water
Lightning
Oxygen
- 8. Multiple Choice
Biochemical Evidence for Evolution relates to...
Similarities in function of tissues and organs amongst species
Similarities in the sequence of genes and proteins amongst species
Similarities on behavioral strategies amongst species.
Is something that has not been studied by evolutionary experts
- 9. Multiple Choice
The diagram below shows a proposed theory of the origin of eukaryotic cells, called endosymbiosis.
Which of the following explains why cells that contained mitochondria-like organelles had an evolutionary advantage?
They were able to photosynthesize
They had more DNA
They were able to make more use of available energy
They were immune to bacterial invasion.
- 10. Multiple ChoiceThe diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?Fossil A and C are the same ageFossil B is older than fossil CFossils A is older than fossil BFossil D is older than fossil C
- 11. Multiple ChoiceThe theory of Endosymbiosis explains...The origin of eukaryotesHow species developHow bacteria evolvedWhy cells rely on one another
- 12. Multiple ChoiceEndosymbiosis gave rise togolgi bodieschloroplasts and mitochondrearibosomes and nucleithe rough and smooth endoplasmic reticulum
- 13. Multiple Choice
According to the theory of endosymbiosis, how did cells acquire mitochondria?
A eukaryotic cell engulfed a virus
A large aerobic cell engulfed a chloroplast
A large anaerobic cell engulfed a small aerobic bacterium
A large anaerobic cell engulfed a photosynthetic bacterium

- 15. Multiple ChoiceWhat is the study of organisms at the early stages of development?DNA studiesembryologyextinctionfossil record
- 16. Multiple ChoiceTwo organisms that are closely related would havevery similar DNA sequenceexactly the same DNA sequencesno proteins in commoncompletely different DNA sequence
- 17. Multiple ChoiceThe similarities of the bones in the diagram provide evidence that---The organisms shown lived in the same natural envionrmentThe organisms shown may have developed from a common ancestorThe organisms shown have the same genetic diseasesAll vertebrate species have identical forelimbs

- 20. Multiple Choice
In the Miller-Urey experiment, a variety of inorganic gases were mixed in a chamber. The gases were chosen to mimic Earth’s early atmosphere. A spark of electricity was passed through the chamber. The gases reacted to form amino acids and other simple organic molecules.
How does the Miller-Urey experiment relate to the history of life on Earth
It provides strong evidence for the mechanism by which the first living things evolved
It suggests a mechanism by which compounds that are essential for life were first assembled
It provides evidence against the hypothesis that life evolved from non-living compounds
It is unrelated to the history of life on Earth because living things were always present in oceans and on land
- 21. Multiple ChoiceMiller/Urey and other scientists have shown that:Life on early Earth required material from spaceCells survived in the primitive atmosphereAmino acids could be produced from inorganic moleculesSimple cells can be produced in a laboratory
- 22. Multiple ChoiceBased upon the conditions of the early Earth, which forms of live most likely appeared first?Prokaryotic and aerobicProkaryotic and anaerobicEukaryotic and aerobicEukaryotic and anaerobic
- 23. Multiple ChoiceThe Miller-Urey experiment of 1953 was designed to test the hypothesis that lightning supplied the energy needed to turn atmospheric gases into organic molecules such as amino acids. Which of the following describes why the Miller-Urey theory is widely accepted today?Amino acids spontaneously form from molecules in the atmosphere todayOrganic molecules are present today in extremely high concentrationsThe process of synthesizing organic molecules from a mixture of gases has been successfully modeled in the laboratoryNo other alternative hypotheses have been introduced
- 24. Multiple Choice
What is the idea that life can arise form nonliving material?
biogenesis
evolution
spontaneous combustion
spontaneous generation
- 25. Multiple Choice
Who was the first scientist to try to disprove the idea of spontaneous generation?
Redi
Needham
Spallanzani
Pasteur
