Which implication might be drawn from the fact that all prehistoric and modern flying vertebrates developed similar structures to support their successful flight capabilities?
29Pterosaurs, birds, and bats developed flight at the same time. This was their single effective adaptation for locating and trapping prey.
Pterosaurs, birds, and bats developed over time in identical ecosystems and environments. These environments influence the forces of flight for these animals.
Pterosaurs, birds, and bats evolved directly from a single species of reptile. Their identical flight structures developed sequentially from the pterosaur to the bat.
Pterosaurs, birds, and bats may have developed similar structures independently of each other. All of the forces are consistent in the development of flight.

If the bodies of present-day bats became fossilized over time, which observation would future scientists likely make about the wings of fossilized bats and pterosaurs?
Both sets of fossils would show similar structures and bone material that were suited for flight.
A comparison of the bones of both organisms would show that the pterosaurs were better suited for flight than bats were.
The bat wing bones would show a completely different structure than the pterosaur bones.
Both sets of fossils would show that the animals were not designed for lengthy, sustained flight.
300s - Q3
Which statement is true about the forces involved in an ornithopter and a pterosaur taking off?
Gravity acts on both the ornithopter and the pterosaur
Drag acts only on the ornithopter and not on the pterosaur.
Lift is the single major factor in the forward movement of the ornithopter.
Thrust resists the motion of the pterosaur and the ornithopter.
300s - Q4
Which factor might limit the knowledge of scientists about the role of pterosaur muscles in flight?
The muscle tissues of prehistoric animals were very different from those of modern animals.
The evidence is inconclusive even though many examples of fossil muscles have been found by scientists.
The evidence suggests that pterosaurs relied much less on muscle strength and more on bone structure.
The number of examples of fossilized bones is greater than the number of fossilized muscle tissue samples.
120s - Q5
Which materials would most likely be used by designers of ornithopters to mimic the bone structures of pterosaur wings?
wooden replicas of bones to create identical structures for the devices
heavy metals to prevent bends and tears in the wings
lightweight metals and open-space structures for the wings
plastic replicas of bones that have a completely filled-in structure
120s - Q6
Which of these statements can be inferred from the data provided by Figure 4?
Wing loading has no influence on the ability of a bird or an object to maintain flight.
Wing loading is influenced only by the weight of the flying object.
The forces of weight and cruising speed have a major influence on the wing loading of a bird or an object.
The forces of drag and weight probably have no influence on the wing loading of a bird or an object.
120s - Q7
Which statement would best describe the successful takeoff of an ornithopter that was designed using the model of the pterosaur?
The object would take off with a powerful amount of thrust and the rapid flapping of small wings.
The object would take off with a minimal amount of thrust and the slow, steady motion of small wings.
The object would take off with a minimal amount of thrust and the slow, steady motion of large wings.
The object would take off with a powerful amount of thrust and the rapid flapping of large wings.
120s - Q8
Which statement best describes the process of the formation of the solar system?
A black hole pulled the gas and dust together.
An explosion pushed the gas and dust together.
Gravity pulled the gas and dust together.
Magnetism attracted the gas and dust together.
120s - Q9
Which statement is the best explanation for the presence of these marine fossils in an inland area of the United States?
The area used to be covered by an ocean.
The fossils were carried to the area by floodwaters.
The crinoids and corals grew on terrestrial surfaces.
The brachiopods could live in water and on land.

Which data set should most likely be expected from the three seismographs?
300s - Q11
Government agencies consider the possibilities of earthquakes when they are developing regulations about new construction projects. Regions of the United States are classified as having a low likelihood of earthquakes (lowest hazard), a high likelihood of earthquakes (highest hazard), or somewhere in between.
Which statement should inform the development of building regulations in regard to earthquakes?
In low hazard areas, building regulations should always include the possibility of the occurrence of an earthquake.
The possibility of earthquakes should be considered by government agencies when writing building regulations only in the areas of highest hazard.
In low hazard areas, government agencies should not consider earthquakes because they will never happen there.
In high hazard areas, government agencies should write building regulations that prevent the construction of all new buildings.

Government agencies consider the possibilities of earthquakes when they are developing regulations about new construction projects. Regions of the United States are classified as having a low likelihood of earthquakes (lowest hazard), a high likelihood of earthquakes (highest hazard), or somewhere in between.
Which statement should inform the development of building regulations in regard to earthquakes?
Building regulations should be strictest in areas of the highest hazard and may be lower in areas of low hazard.
In low hazard areas, building regulations should always include the possibility of the occurrence of an earthquake.
The possibility of earthquakes should be considered by government agencies when writing building regulations only in the areas of highest hazard.
In high hazard areas, government agencies should write building regulations that prevent the construction of all new buildings.

A student has a remote control for a television. The student points the remote at the television and presses a button on the remote labeled Volume. A small red light flashes on the front of the remote. The student observes that the sound from the television becomes lower.
Which statement best describes how the remote control communicates with the television to change the volume of the sound?
The remote control sends low-energy infrared radiation to a light detector on the front of the television.
The remote control sends microwaves toward the television that are absorbed by the front of the television.
The remote control sends sound waves in many directions, which bounce off the walls of the room toward a vibration detector on the front of the television.
The remote control sends radio waves in many directions, which bounce off the walls of the room toward the front of the television.

These data tables show the distance of various galaxies from Earth in millions of light-years (Mly) at different times. Which table supports the theory of expansion in the formation of the universe?
300s - Q15
Which inference about the chipmunk population can be supported with the data gathered by the biologist?
The amount of food in the area decreased, causing more chipmunks to survive to reproductive age.
Chipmunks in later generations showed greater genetic diversity than previous generations, allowing for a greater survival rate in later generations.
Individual chipmunks changed their genetic makeup and became more successful in the environment.
Chipmunks migrated from one country to another country to increase the number of chipmunks in the studied area.
