- 1. Multiple Choice
Where the better adapted organisms survive to pass traits along to offspring.
Evolution
Natural Selection
Extinction
Artifical Selection
- 2. Multiple ChoiceWhat is the advantage of having different shaped beaks?To look different from other species.To be able to eat the food readily available in the environment.To protect itself against predators.To protect itself against prey.
- 3. Multiple ChoiceThe theory of evolution by natural selection means that what is changing over time?The inherited traits of a population.The acquired traits of a population.Hair color and eye colorAttractive features.
- 4. Multiple ChoiceWhy are advantageous traits more likely to be passed onto offspring?Because they are more likely to survive and reproduce.Because they come from dominant alleles.Because they come from recessive alleles.Because the trait is an acquired phenotype.
- 5. Multiple ChoiceThe differences among a species, like different bird beaks, are calledgenes.variations.traits.theories.
- 6. Multiple ChoiceDo organisms "decide" to evolve and change?Yes, they know they need to change to surviveNo, they change because of natural selection
- 7. Multiple ChoiceWhich organisms are most likely to survive?the best adaptedthe fastestthe strongestthe most domesticated (tamed)
- 8. Multiple Choice

natural selection
mutation
camouflage
adaptation

- 10. Multiple Choice
The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?Dark mothLight mothBoth will be equally successfulNeither will be successful - 11. Multiple ChoiceSince the 1800s humans have stopped burning coal, and the trees have returned to their original color. Which moth will be more successful in this environment?Dark mothLight mothBoth will be equally successfulNeither will be successful
- 12. Multiple ChoiceWhat process is being shown in this image?VariationNatural SelectionSelective BreedingHomeostasis
- 13. Multiple ChoiceWhy is the mouse population changing over time?The light mice can reproduce more successfully than the dark miceThe hawks eat more dark mice than light mice because the dark mice taste betterThe hawks eat more light mice than dark mice because they can see the light mice more easilyThe hawks eat more dark mice than light mice because they can see the dark mice more easily
- 14. Multiple ChoiceThese moths are all the same species. The differences between their wings is an example of ________________Natural SelectionVariationHomeostasisExtinction
- 15. Multiple ChoiceOrganisms that are better adapted to the environment survive to pass traits to their offspringNatural SelectionHomeostasisSelective BreedingExtinction
- 16. Multiple Choice

- 18. Multiple Choice
The more genetic variation a population has,
the more likely it is for some individuals to
evolve
migrate
survive
mutate
- 19. Multiple ChoiceIndividuals that are well adapted to their environment will survive and produce:Fewer mutationsStronger genesMore offspringBetter traits
- 20. Multiple ChoiceAccording to the theory of natural selection, some individuals more likely than others to survive and reproduce because they:pass on to their offspring their newly acquired traits.are better adapted to their environment than others and will pass on those adaptations to future offspring.do not pass on newly acquired traits.produce fewer offspring than others in the same environment.
- 21. Multiple ChoiceNatural selectionprocess by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittestHumans select which animals live and diebothIDK
- 22. Multiple ChoiceIntentional breeding of organisms with desirable traits so that offspring have similar desirable traits.MutationNatural SelectionEvolutionSelective Breeding
- 23. Multiple ChoiceAccording to the theory of natural selection, what is likely to happen to a population of birds after the seeds they normally eat are no longer available and all that is left are seeds that are harder to crack open?
Note: a population is a group of individuals of the same species.The individual birds that already have the kind of beak that allows them to eat the seeds that are harder to crack open would be more likely to survive and reproduce.All of the individual birds would develop new beaks as they attempt to eat new seeds. All of the birds would survive and reproduce.Some of the individual birds would try to develop new beaks so that they could eat the seeds. Those birds would be more likely to survive and reproduce, and the other birds would likely die.Because the population of birds is all of the same species, they all have the same physical traits. No individual bird would have an advantage in cracking open the seeds, and all of the birds would die. - 24. Multiple ChoiceWhich of the following correctly describes what happens when a population of bacteria becomes resistant to an antibiotic?When subject to antibiotics, each bacterium tries to become resistant. Only some are able to do this and passes it on to their offspring.When subject to antibiotics, all bacteria become more resistant to it if they are exposed to it longer.When subject to antibiotics, most bacteria will die. Randomly some bacteria will become resistant and pass this on to their offspring.When subject to bacteria, only those individual bacteria that already have a trait that helps them survive the effects of the antibiotic will live and pass it on to their offspring.
- 25. Multiple ChoiceNatural selection is best described as...The ability to generate new adaptations that better suit the species.The mechanism that leads to perfect species.Variations of traits causes those better suited to the environment to survive and reproduce.Causing the death of a significant part of the population.
- 26. Multiple ChoiceWhich population of organisms would be in greatest danger of becoming extinct?A population of organisms having few variations living in a stable environment.
A population of organisms having few variations living in an unstable environment.A population of organisms having many variations living in a stable environment.
A population of organisms having many variations living in an unstable environment. - Answer choicesTagsAnswer choicesTags
