Dogs
Panda bears
Snakes
Jellyfish
- 2. Multiple Choice
In 1977, Daphne Major experienced a severe drought. The figure shows the beak depths of the initial population of medium ground finches before the drought (red bars), and of the drought survivors (black bars). What do the data show? Select all that apply.
The most common beak depth of the initial population (red bars) was 8.8 mm. A very small proportion of individuals with this beak depth survived the drought.
More than half of the initial finch population died during the drought.
The most common beak depth of the surviving population (black bars) was 10.3 mm. Less than a quarter of individuals with this beak depth from the initial population survived the drought.
Finches with larger beaks had a survival advantage in the 1977 drought.
- 3. Multiple Choice
The top figure shows the beak depths of the 1976 finch population (red bars) before the drought, and the population after the drought (black bars). The lower figure shows the beak depths of the offspring of the drought survivors in 1978. What do these figures tell us?
The average beak depth of the 1978 offspring population is larger than that of the original 1976 population.
The finches that survived the drought (black bars in first graph) had offspring (red bars in second graph) with on average much larger beaks than their parents.
The offspring (red bars in second graph) had a smaller range of beak depths - from smallest to largest - than their parents (black bars).
The size of the offspring population in 1978 is much larger than the initial 1976 population, before the drought.
- 4. Multiple Choice
Mutations are caused by selective pressure in the environment.
True
False
- 5. Multiple Choice
The same mutation could be advantageous in some environments but deleterious in others.
True
False
- 6. Multiple Choice
The appearance of dark-colored volcanic rock caused the mutation for black fur to appear in the rock pocket mouse population.
True
False
- 7. Multiple Choice
The Rock Pocket mice move to the environment that matches their fur.
True
False
- 8. Multiple Choice
Dark mice are more likely to survive in the dark rocks because the predators cannot see them as easily.
True
False
- 9. Multiple ChoiceA population of cockroaches was sprayed with an insecticide. Some cockroaches survived and produced a population of cockroaches that was resistant to this spray. What can BEST be inferred from this example?species will adapt no matter what the environmentenvironment has no effect on the survival of an organismIndividuals with favorable variations survive and reproduceInsecticides cause mutations that are passed on to the next generation
- 10. Multiple Choice
Why did dark moths have a survival advantage when they were near factories?
They could hide in the birds shadow.
They could push the white moths into the flames.
They did not have a survival advantage.
They blended in with the dark tree trunks.
- 11. Multiple ChoiceWhy did the population of moths changePredators were able to easily see their prey.People hunted lighter colored mothsWhite moths were killed by the smoke from the factoriesMoths mood changed to sad, causing them to become dark
- 12. Multiple Choice
Why did the number of white peppered moths decrease so much by 1895?
they did not blend in with the trees and birds ate them
they tasted better to the birds than the black moths
they were easier to reach on the trees
white moths flew away to find better trees to blend in with
- 13. Multiple Choice
The phenomenon that refers to the evolution of dark body colors in animal species that live in habitats blackened by soot is known as
industrial revolution
industrial melanism
pollution selection
Kettlewellanism
- 14. Multiple Choice
Why do moths and other organism reproduce so many eggs or offspring?
so that their babies can have friends to play with
the more offspring the more likely the offspring will survive
the more offspring the less likely offspring will survive
the more offspring the less competition
- 15. Multiple ChoiceNatural selection is the process by whichchange occurs in the genetic characteristics of individuals that live together in an environment from one generation to anotherorganisms with traits well-suited to their environment reproduce at a greater rate than less well-adapted organisms in the same environmentuse and disuse of a characteristic leads to evolutionary changebaseball players pass on the trait for strong arm muscles to children
- 16. Multiple ChoiceIn natural selection, the selective agent is thehumansmutationsbreedersenvironment
- 17. Multiple Choice
The earliest ancestor of corn is a grassy plant called?
Teosinte
Triticum
Hordeum
Aramanthaceae
Avena
- 18. Multiple Choice
TRUE or FALSE: Natural selection will still occur if individuals are exactly the same.
TRUE
FALSE
- 19. 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.
- 20. Multiple ChoiceDefinition: natural selectioninherited characteristic that increases chances of survivalorganisms with traits well suited to their environment survive and reproduce at a greater ratea growing population causes a scarcity of resourcesdifferences in the DNA sequence
