- 1. Multiple ChoiceThis mechanism of evolution occurs when individuals migrate between populations.ExtinctionGene flowGenetic driftNatural Selection
- 2. Multiple ChoiceGenetic drift is change in the allele frequency of a population due to...random chancenatural selectionnon-random mating (sexual selection)artificial selection
- 3. Multiple ChoiceWhich of the following is an example of the bottle neck effect?Bald Eagles are hunted until near extinction, population recovers.Small group of iguanas floats to an island, starts a new population.Red fox pups are more likely to survive in a snowy environment if they are born white.Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.

Which of the following is an example of natural selection?
Bald Eagles are hunted until near extinction, population recovers.
Small group of iguanas floats to an island, starts a new population.
Red fox pups are more likely to survive in a snowy environment if they are born white.
Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.
- 5. Multiple ChoiceFive hundred years after the deer had established a flourishing population in the park, a few of them venture back to their original woods and have babies with the deer there.Genetic DriftMutationsNon-random matingGene flow
- 6. Multiple ChoiceYellow toucan birds seek out one another to make babies together and tend to avoid the green toucan birds.Genetic DriftNon-random matingGene flowMutation
- 7. Multiple ChoiceOne day a group of scientists collected a small group of brown anole lizards from a large group of the lizards. Then they placed this small group of lizards on an island that had no brown anole lizards on it. What is this an example of?Bottleneck EffectHardy EffectFounder EffectNone of These
- 8. Multiple ChoiceStructures with the same parts have different functions; suggests that organisms share a common ancestryvestigial structureshomologous structuresadaptive radiationfossil
- 9. Multiple ChoiceStudy of embryos of various organisms to show a common ancestor because of similarities in developmentnatural selectionembryologyspeciationevolution
- 10. Multiple ChoiceSome organisms that share a common ancestor have features that have different functions, but similar structures. These are known asvestigial structuresanalogous structureshomologous structuresfossil structures
- 11. Multiple ChoiceHow do fossils provide evidence that evolution has happened on Earth?Fossils show how the sizes of certain animals has changed drastically over millions of yearsFossils show that some species have gone extinctFossils show how life forms present today are different than those from the pastDifferent sedimentary rock layers provide evidence for how the environment has changed over time
- 12. Multiple Choice
Vestigial structures
structures that perform a similar function but are not similar in origin
remnants of once-important structures that have slowly lost all or most of their function
features found in different organisms that share structural similarities but may have very different functions
preserved remains of an organism
- 13. Multiple ChoiceWhich layer is the youngest1234
- 14. Multiple Choice
SELECT ALL THAT APPLY: Which of the following must be true in order for organisms to be considered the same species?
They must be able to mate
They must be able to produce viable offspring
They must have structural similaries
They must have the same bone structure
- 15. Multiple ChoiceWhat happens when species produce too many offspring?Species share the limited resourcesSpecies eat less so that all can surviveOnly those that are least fit can surviveOnly those that are best fit can survive
- 16. Multiple Choice
Why is it important to finish ALL of an antibiotic, even if you feel better?
If all of the infectious bacteria are not killed, the bacteria may continue to multiply. Some of these bacteria may have a mutation that makes them resistant to the antibiotic. This could cause resistant bacteria to spread.
If all of the antibiotic is not used, the surviving bacteria may learn how to fight off the antibiotic, causing the sickness to get even worse.
If all of the antibiotic is not used, the bacteria may begin ingesting your skin cells, causing a new sickness to arise.
If all of the antibiotic is not used, the surviving bacteria may cooperate with other infectious bacteria, resulting in two separate infections at the same time.
- 17. Multiple Choice
People are making antibiotic resistance worse by:
Taking antibiotics only when they need them
Not finishing the full course of prescribed antibiotics
Not sharing antibiotics with others
Taking antibiotics for when they have a virus
- 18. Multiple ChoiceHow has antibiotic resistance changed over time?It hasn't changed at allAntibiotics are being made cheaply and bacteria are becoming more resistantHumans are buying less antibiotics and becoming weakerBacteria are becoming more resistant to the antibiotics that are being perscribed
- 19. Multiple Choice
If you take antibiotics only the resistant bacteria survive and the non-resistant bacteria die. This is an example of...
Resistance
Survival of the fittest
How antibiotics work
- 20. Multiple Choice
To prevent antibioitc resitance from developing you must...
Only use antibiotics when needed
Only take half of the course of antibiotics
Only take antibioitcs for viruses
Complete the full course of antibiotics
