Quarterly 2 Review--2016-2017
Test Description: Unit 2-2016-2017
Instructions: Answer all questions to get your test result.
1) A population of a certain kind of fish is introduced into a new habitat. These fish have variations in color from light to dark. Because of the lighting conditions and predators in this new habitat, light colored fish survive better near the surface
A
A. All the fish would become more similar, something exactly between light-colored and dark-colored.
B
B. None of the fish would be able to survive, because the new habitat is not suited to any of them.
C
C. There would be two populations of fish, light-colored near the surface and dark-colored near the bottom.
D
D. The fish would become smaller over time so that they could more easily defend themselves from predators.
2) A deer is born with lighter colored fur. How does this affect the deer’s probability of survival in an environment with a predator? The probability of survival will:
A
None of the above
B
Decrease
C
Increase
D
Stay the same
3) If a new, light colored predator that hunts near the surface is introduced into the habitat, what is likely to happen to the population?
A
The population of dark colored fish will increase
B
More dark colored fish will move to the surface
C
The population of light colored fish will decrease
D
More light colored fish will be born to replace the ones eaten
4) Which fossil is the youngest, most recent fossil presented in undisturbed rock layers?
A
The one in the bottom layer of rock
B
The one that shows up the most.
C
The one in the top later of rock.
D
The one in the middle layer of rock
5) Characteristics that help an organism survive and reproduce
A
Adaptations
B
Variations
C
Mutations
D
Selections
6) An example of natural selection
A
Organisms that are better-adapted to their environment survive, reproduce, and pass their t
B
When humans select certain genes to be bred into future generations
C
When organisms do not adapt and become extinct.
D
Animals that are not disease resistant.
7) What is the Theory of Plate Tectonics?
A
When sediments are compacted and cemented together.
B
As the seafloor spreads, the continental plates move,causing the earth's crust t continuously change.
C
Matching rock layers on various continents.
D
The formation of earthquakes and volcanoes.
8) Plant fossils were found on the east coast of South America and west coast of Africa. How did they get there when the Atlantic Ocean is in between?
A
The continents were once joined together.
B
Humans transported the fossils from point A to point B.
C
The fossils were able to swim from one continent to the other
D
The fossils developed independently on both continents.
9) The similarities and differences in limbs of 3 different mammals suggest that all three species developed from the same ancestor, but
A
moved to similar habitats.
B
became extinct.
C
lived in different time periods.
D
adapted to different habitats.
10) Explain why the skeletal structures of the dolphin's flipper and a cat's leg are similar?
A
Dolphins and cats have the same exact genes.
B
Dolphins and cats have a common ancestor
C
Dolphins and cats are used for selective breeding.
D
Dolphins and cats have the same mutations
11) Evidence of plate movement
A
Fossils have only been found on one continent.
B
Species of organisms in the fossil record have changed over geologic time.
C
Fossils are only found in the bottom rock layers.
D
Fossils usually found in warm areas have been found in cold areas.
12) Evidence of an ancestral relationship is discovered among 3 organisms(whales, cats, and horses) when making observations of their early embryos?
A
All of the organisms start out small in size even though the whales and horses grow larger.
B
All of the organisms start out with no hair or feathers
C
At an early stage, all of the organisms have a curved shape and no fur.
D
At an early stage, all of the organisms have fur and vertebrae
13) Whales, which live in the water, have hips. These structures are important for carrying the weight of animals that walk on land. Finding this body part in animals that don’t walk on land is best explained how?
A
Whales share a common ancestor with animals that walk on land.
B
Whales have evolved this structure because it might be useful in the future.
C
Whales have a diet that includes other animals that have this structure.
D
Whales are able to interbreed with other animals that have hips.
14) Groups of organisms are related through a shared evolutionary history. What would be evidence of this?
A
Similarities in body structures
B
The habitats in which the animals live
C
Observations of interactions in the wild
D
Competition between organisms for resources
15) New seafloor material is formed at places in Earth’s crust where –
A
rock is broken into pieces as tectonic plates push against one another.
B
lava flow from volcanic eruptions builds up over many thousands of years.
C
magma rises into the spaces where tectonic plates pull away from one another.
D
one tectonic plate slides beneath another and is forced downward.
16) Which of the following provides evidence that the continents on tectonic plates have moved away from each other in the past?
A
The composition and thickness of rock layers varies at different depths.
B
Fossils of the same plants and animals are found on widely separated continents.
C
Ocean currents can be disrupted near boundaries between tectonic plates.
D
The frequency of volcanic activity is higher at edges of tectonic plates.
17) A certain species of freshwater frogs varies in several characteristics. All have spots, but the size and number vary. Males of the species vocalize loudly while, females are silent. All the frogs eat insects, but some frogs are more successful hunte
A
Females will also make sounds.
B
More frogs will enter an inactive state.
C
All frogs will have more and larger spots.
D
Most frogs will be better at catching insects.
18) Which of the following is required for a trait to become more common over time in a population?
A
The trait must be the result of an immediate change in the environment.
B
The trait must allow members of the population to eat only some kinds of food.
C
The trait must give individuals an advantage in producing offspring that survive.
D
There must be many varieties of the trait in the population.
