True
False
- 2. Multiple Choice
What is most likely to happen to moth populations in the picture shown?
Light moths--hunted easily, dark moths--population increase
Dark moths--hunted easily, dark moths--population increase
Light moths--hunted easily, light moths--population increase
Lights moths will change their color to match dark moths.
- 3. Multiple Choice

TRUE
FALSE
- 4. Multiple Choice
How do you "win" at natural selection?
survive
go extinct
survive & reproduce
- 5. Multiple Choice
Due to pollution, a pond becomes darker over time. Which trait variation became more common?
light fish
dark fish
- 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 Choice

light colored moths
dark colored moths
red colored moths
red and light colored moths
- 8. Multiple Choice

- 9. Multiple ChoiceWhich organisms are most likely to survive?the best adaptedthe fastestthe strongestthe most domesticated (tamed)
- 10. Multiple Choice
Change in a population over time that descend from a common ancestor.
Natural Selection
Selective Breeding
Homeostasis
Evolution
- 11. 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

- 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 ChoiceDo organisms "decide" to evolve and change?Yes, they know they need to change to surviveNo, they change because of natural selection
