Front 2

Describe the lithosphere and the asthenosphere.

Back 2

The lithosphere is rigid and immovable, and the asthenosphere is hot and flowing.

Front 3

Disease destroys a light colored lichen (moss) that helped disguise a light colored insect that hid there from its prey. How will the environmental change affect the number of light colored lichen?

Back 3

The number of insects will decrease because the predators will see the insects more easily.

The waves travel from a less dense material into a more dense material.

Front 12

How can the wavelengths of light from a distant galaxy be used to determine the distance between the Earth and the galaxy?

Back 12

Front 16

If the Southern Hemisphere is leaning toward the sun, what will the days be like?

Back 16

The days will be longer.

Front 17

What are some logical arguments in favor of selective breeding in plants?

Back 17

grass that can grow with less water, wheat that can grow in different soils, oranges that are not affected by freezing temperatures

Front 18

A scientist completed an experiment. A coworker gave him some additional information that he should consider. How should the scientist respond to the coworker's alternative conclusion?

Back 18

Dr. Jordan should reanalyze the
results to take into consideration
his coworker’s suggestion.

Front 19

Which adaptations have allowed ospreys to survive in their environment?

Back 19

• Thick, oily feathers for water resistance
• Strong feet and sharp claws for grasping fish
• Strong, muscular legs for carrying the fish back to land

Front 20

The owners of a property that had a pond sprayed insecticide that destroyed the mosquito eggs.
How will this affect the flow of energy in the food web?

Back 20

Without mosquitoes available as a food source, less energy will be available to the frogs.

Front 21

The number of trout decreased due to the overfishing by humans. Describe the impact of this change on the other organisms in the large lake.

Back 21

Eagles will lose a source of energy and need to get energy from gulls, forage fish, and
snapping turtles.

Front 22

Describe how Earth's orbit around the sun determines the seasons.

Back 22

The Earth's axis tilts different parts of the Earth toward or away from the sun

Front 23

In a Mississippi forest floor, how would the disappearance of dead leaves from the forest floor affect spiders?

Back 23

Their population would decrease because they eat animals that depend on dead leaves
for energy.

Front 24

Meg investigated the ability of different plants to decrease soil erosion. What is a logical inference for this
investigation?

Back 24

The cloudier the water, the more soil that eroded and the less able the plant was to prevent
soil erosion.

Front 25

A type of radiation can damage cells of living things and is blocked by Earth’s ozone layer
Which type of radiation does this describe?

Back 25

ultraviolet

Front 26

During which season does sunlight strike the Northern Hemisphere most directly?

Back 26

summer

Front 27

What is the outcome of the collision between oceanic and continental crust?

Back 27

oceanic crust will subduct beneath the continental crust

Front 28

In an energy pyramid for a wetland, the river otter is at the top of the pyramid. What information does this tell you?

Back 28

River otters are tertiary consumers and have the least energy available to them.

Front 29

What is flawed about the design for an earthquake warning system, where seismographs are used?

Back 29

The design is flawed because forces of Earth are unpredictable and solutions are unreliable at times.

Front 30

Astronomers use instruments that orbit Earth in order to detect cosmic x-rays emitted by stars.
Why do these instruments need to be located in Earth’s orbit in order to work properly?

Back 30

Earth’s atmosphere absorbs much of the cosmic radiation.

Front 31

Bubbles are formed when an acid is mixed with baking soda. What will we most likely see when we mix water, milk and dish soap with baking soda?

Back 31

Water, milk, and dish soap must not be acids because they do not form bubbles when
mixed with baking soda.

Front 32

How is the shape of a pyramid related to energy flow within an ecosystem?

Back 32

Only a small amount of energy from one trophic level is available to organisms at the next highest level.

Front 33

Describe what happens during an equinox.

Back 33

The tilt of Earth’s axis is neither

• The field strength at 10 centimeters will be 5 microteslas.

Front 36

What can scientists conclude about a galaxy whose light is shifted toward shorter wavelengths?

Back 36

The galaxy is relatively close since a distant galaxy’s light is shifted toward longer wavelengths.

Which adaptations provide an organism from a grassland ecosystem with the greatest chance for surviving the drought?

Back 41

• Long neck to reach vegetation in
tall trees
• Able to survive long periods
without water

Front 42

Data indicates that salt content in water in a coastline environment is increasing. What adaptations allow the red mangrove to survive in this coastline environment?

Back 42

Roots with a filtration system that allows water to enter but keeps out the larger salt molecules

Front 43

Explain how bacteria use the oil they consume?

Back 43

The oil is chemically broken down
by oxidation, releasing energy in the process.

Front 44

A scientist wants to run an experiment a second time but provide different amounts of oil for each colony
of bacteria.
How would this affect the validity of any conclusion for this experimental design?

Back 44

It would not be valid because the
amount of oil provided is not being
controlled.

Front 45

A university biologist is skeptical of s scientist's conclusion. She suggests
that the oil used in an experiment could have broken down naturally and may not have been consumed by the bacteria. How should the team of scientists address this concern?

Back 45

Run the experiment several times,
but use oil that does not break down naturally.
