- 1. Multiple Choice
Which row correctly pairs a finch species with its primary nutritional role and bill type?
1
2
3
4
- 2. Multiple Choice
On various Galapagos islands, finch species have different diets: seeds, insects, flowers, the blood of seabirds, and leaves. This is evidence that each species has a different
mating behavior
nesting material
niche
predator
- 3. Multiple Choice
Which statement best explains the differences observed in the tortoises on each island?
Each tortoise adapted to its environment during its lifetime.
Sudden mutations changed the appearance of all of the tortoises.
The tortoises grew different structures based on the available food.
Different adaptations gave some tortoises a better chance of survival.
- 4. Multiple Choice
When the saddle-backed tortoises extend their long necks out of the shell, they are unprotected from attack. Scientists hypothesize that during the evolution of this tortoise, they had few predators. Which statement best supports this hypothesis?
Competition between the predators and the tortoises would have resulted in a greater number of long-necked tortoises.
The number of predators was greater than the number of tortoises.
Saddle-backed tortoises were not a part of the food chain.
Predators would have killed the tortoises with long necks, leaving more tortoises with shorter necks.
- 5. Multiple Choice
The extremes of dry and wet weather of the Galapagos Islands cause the food supply to constantly change. During dry years, the food is mainly large, hard seeds, and finches with large beaks are found in greater numbers.
Which statement best explains this observation?
Large beak size is an adaptation to dry conditions.
Finches grow larger when they have more water.
Dry environments cause mutations in finches
Small finches become smaller during dry
seasons.
- 6. Multiple Choice
Studies of the finches of the Galapagos Islands have shown that
the beak of a finch will change if the environment of the bird remains stable
a bird's beak changes annually in response to the type of food that is most abundant each year
natural selection occurs when there are scarce resources and intense competition
DNA will change to produce structures needed by birds to survive intense competition
- 7. Multiple Choice
Which of the following statements best explains the variation in the beaks of these four species?
Over time, an abundance of seeds for food led to increased differences between the species.
Competition for limited food resources led to selection for different traits.
Over time, an abundance of seeds for food led to increased similarities between the species.
Competition for limited food resources led to selection for similar traits.
- 8. Multiple Choice
The success of the finches on the Galapagos was most likely due to the
large numbers of other birds competing for food
birds adapting to different niches
birds occupying the same island
mutations occurring in every offspring
- 9. Multiple Choice
The seed-eating finch in the given diagram was most likely the
common ancestor
most successful
largest finch
parent of the other finches
- 10. Multiple Choice
How might an extended period of drought influence the ground finch population in the given situation?
Drought increases seed availability, and all ground finches would be more numerous.
Drought decreases seed availability, but has no influence on the ground finch.
The birds with smaller beaks would be more numerous.
The birds with larger beaks would be more numerous.
- 11. Multiple Choice
How would the introduction of another species of seed-eating ground finch to the island most likely influence the medium ground finch in the given situation?
The medium ground finch would become a parasite of the introduced species.
The finches would not compete, since they both eat seeds.
The finches would interbreed and produce a new species of finch.
The medium ground finch would face increased competition for seeds
- 12. Multiple Choice
Based on the information given, which factors most likely had a role in the development of beak characteristics in the medium ground finch?
genetic engineering and selective breeding
unchanging environment and the need to reproduce
variation and recombination
mutation and cloning
- 13. Multiple Choice
The most likely explanation for the variation in the beak size of the medium ground finch shown in the graph is that
the birds acquired larger beaks so they could take advantage of the supply of small seeds
different adaptations gave some birds a better chance for survival
the birds with smaller beaks mutated due to the drought so they produced more offspring
the environment caused the birds to exercise their beaks and the beaks became longer and stronger
- 14. Multiple Choice
The diagram of the island suggests that in region B finches can feed on
a large variety of different-sized seeds
large seeds and insects
small seeds, only
insects and a limited number of small seeds
- 15. Multiple Choice
There are two different species of finch that live on the same small island, species A and species B. Both species successfully feed and reproduce on the island. Species A nests in pine trees and eats large seeds.Species B nests in hollowed-out dead logs and eats small insects.
Both bird species A and species B mentioned in the reading passage can most likely survive on the same
small island because they
use different resources and, therefore, they do not compete
compete for food, but do not compete for shelter
mate with each other, keeping both populations constant
eat the same food, but feed at different times of the day
- 16. Multiple Choice
Warbler finches are classified as
producers
decomposers
carnivores
herbivores
- 17. Multiple Choice
The differences observed in the bird beaks in the given diagram are most likely due to
the genetic engineering of the DNA of each of these species
the selection for different shaped beaks that best suit different niches
the genetic recombination associated with mitotic cell division
asexual reproduction of these finch species
- 18. Multiple Choice
Which species of finch has an edge-crushing bill that can also probe into plants for food?
warbler finch
sharp-billed ground finch
cactus finch
large ground finch
- 19. Multiple Choice
One finch that would most likely compete with the warbler finch for food is the
cactus finch
vegetarian finch
sharp-billed ground finch
woodpecker finch
