- 1. Multiple Choice
Why 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 organism knew it needed that trait, survives, and passes it on.
- 2. Multiple Choice
Mutations are a change in what?
DNA
tRNA
protein
rRNA
- 3. Multiple ChoiceThe differences among a species, like different bird beaks, are calledgenes.variations.traits.theories.
- 4. Multiple Choice
Why 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 - 5. Multiple ChoiceWhat process is being shown in this image?VariationNatural SelectionSelective BreedingHomeostasis
- 6. Multiple Choice
Where do adaptations come from?
The individual organism decides to adapt
Mutations that give an organism an advantage in its environment
Genetic recombination during meiosis
Both mutations and genetic recombination are sources of adaptation
- 7. Multiple Choice
"Organisms that are better adapted to the environment survive to pass traits to their offspring" is the definition of
Natural Selection
Evolution
Selective Breeding
Artificial Selection
- 8. Multiple Choice
Which best describes the role of mutations in natural selection?
Mutations help an organism to better survive in their environment
An organism may acquire a helpful mutation by interacting with the environment
A mutation may result in a beneficial trait that makes an organism more likely to survive and reproduce
Organisms with certain traits are more likely to win competitions for mutations
- 9. Multiple Choice
All rabbits of the same species living in a particular area would be an example of a(n)
population
species
community
ecosystem
- 10. Multiple Choice
The more genetic variation a population has,
the more likely it is for some individuals to
evolve
migrate
survive
mutate
- 11. Multiple Choice
Mutations are important because they bring about
death of the organism in which they develop
genetic variation needed for a population to evolve
benefits for the individual, not for the population
changes in genotype, but not phenotype
- 12. 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
- 13. Multiple ChoiceWhich organisms are most likely to survive?the best adaptedthe fastestthe strongestthe most domesticated (tamed)
- 14. Multiple ChoiceDo organisms "decide" to evolve and change?Yes, they know they need to change to surviveNo, they change because of natural selection
- 15. Multiple ChoiceThe long and sharp beak of a woodpecker is an example of:Natural SelectionSelective Breeding
- 16. Multiple ChoiceDomesticated dogs are an example of:Natural SelectionSelective Breeding
- 17. Multiple Choice
Why is competition important for natural selection?
It shows which variations are more successful, allowing the organisms with those variations to survive.
It causes organisms, regardless of which traits they have, to die out, reducing the population size.
It causes organisms to get stronger due to having to outcompete other species.
Competition is not important for natural selection.
