- 3. Multiple ChoiceWhere the better adapted organisms survive to pass traits along to offspring.EvolutionNatural SelectionExtinctionArtifical Selection
- 4. 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.
- 5. 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.
- 6. 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.
- 7. Multiple ChoiceMutations are a change in what?DNAtRNAgenotypephenotype
- 8. Multiple ChoiceAll mutations and adaptations usually lead to what process?selective breedingbehavioralnatural selectiongenetic engineering
- 9. Multiple ChoiceWhy do frogs and other organism reproduce so many eggs or offspring?so that their babies can have friends to play withthe more offspring the more likely the offspring will survivethe more offspring the less likely offspring will survivethe more offspring the less competition

- 15. Multiple Choice
A species could go extinct if:
food becomes more plentiful.
members of the species have adaptations to enhance survival.
the environment changes drastically and no one can adapt.
there is less competition for resources.
- 16. Multiple Choice

How do artificial selection and natural selection differ?
In artificial selection, the environment acts as the selecting agent.
In natural selection, traits that are useful to humans are inherited.
In natural selection, humans act as the selecting agent.
In natural selection, the environment acts as the selecting agent.
