The predator population will stay the same in year 6 because the prey population will be extinct.
The predator population will increase in year 6 because the prey population is increasing.
The prey population will decrease in year 6 because the predator population is decreasing.
The prey population will increase in year 6 because the predator population will be extinct.
Using wool is unsustainable because sheep require a lot of land.
Using wool is sustainable because wool clothing can be thrown away.
Using wool is unsustainable because recycling is not always possible for every item.
Using wool is sustainable because wool clothing can benefit the land the sheep use.
The western tarnished plant bug and the whitefly are two types of garden and crop pests. Instead of using chemical pesticides, some gardeners and farmers plant marigold flowers as a natural pest repellent. How could this strategy improve outdoor environments?
Planting marigolds costs less than using chemicals.
Planting marigolds removes pollinators as well as other pests.
Planting marigolds is a safe and attractive way to eliminate pests.
Planting marigolds attracts different pests that are easier to eliminate.
The seat belts in a car are made from nylon. Nylon is a material that humans make from petroleum. Which statement is best supported by this information?
Nylon is made from renewable natural resources.
.Nylon is made from renewable synthetic resources.
Nylon is made from nonrenewable natural resources.
Nylon is made from nonrenewable synthetic resources.
A chemical reaction occurred because a new substance was made.
A chemical reaction occurred because the two liquids had different densities.
A chemical reaction did not occur, because a change in state is evidence of only a physical change and not a chemical change.
A chemical reaction did not occur, because the mass of the liquids before mixing was equal to the mass of the yellow solid.
A student wants to investigate how the mass of a toy car affects its motion. The student will use a ramp, a block, and four toy cars. Each toy car has a different mass. Which data should the student measure during this investigation?
the length of each toy car
the color and shape of each toy car
the amount of force used to hold each toy car at the top of the ramp
the distance each toy car pushes a small block placed at the end of the ramp
It shows a full moon, which happens when the Moon rotates so its dark side faces Earth.
It shows a new moon, which happens when the Moon rotates so its bright side faces Earth.
It shows a solar eclipse, which happens when the Moon is directly between Earth and the Sun.
It shows a lunar eclipse, which happens when the Moon is directly between Earth and the Sun.
The moon is traveling too slowly relative to its size.
The force of gravity is shown acting in the wrong direction.
The orbital path should be shown as straight instead of curved.
The labels for “speed” and “orbital path” should switch positions.
The cave forms slowly because water must flow through rock layers many times for the rock to dissolve.
The cave forms slowly because solid rock layers at the surface prevent water from seeping into the layers underground.
The cave forms quickly because large amounts of water enter the opening when a sinkhole forms at the surface.
The cave forms quickly because fast-moving water erodes rock rapidly and causes rock fractures to increase in size.
The “identify the problem” step would be different because it is not possible to identify problems within computers.
The “generate possible solutions” step would be different because this step is not needed for a bridge.
The “create a model of the solution” step would be different because it is not possible to build a model of a bridge.
The “test the model” step would be different because bridges and computers do not work the same way.
Solar panels should be used instead of wind turbines because they are harder to maintain.
Solar panels should be used instead of wind turbines because they can generate electricity at night.
Solar panels and wind turbines are both good options if the conditions are appropriate at their locations.
Solar panels and wind turbines both have harmful effects on wildlife that should limit their use.
Moving the tires from car Y onto car X so that car X will not slip.
Switching the bottle from car X to car Y to reduce air resistance.
Blowing less air into the balloon on car X so the balloon will release air faster.
Using a smaller rubber band on car Y so car Y will have a higher initial speed.
Most trees in zone 1 were destroyed or damaged. Trees in zone 2 were coated with ash, and their growth rate slowed. Trees in zone 3 were coated in ash until rain washed off the ash; these trees had no change in growth.
Trees use the Sun’s energy to convert oxygen and glucose into water during photosynthesis.
Trees use the Sun’s energy to convert oxygen and glucose into water during cellular respiration.
Trees use the Sun’s energy to convert water and carbon dioxide into glucose during photosynthesis.
Trees use the Sun’s energy to convert water and carbon dioxide into glucose during cellular respiration.
The area where Mount Saint Helens formed is on a continental plate next to an oceanic plate. The volcano has erupted several times during the past 40,000 years. Which statement best explains the process that formed Mount Saint Helens?
Mountains formed from rising magma at a divergent boundary.
Earthquakes at a subduction zone caused many landslides over time, which formed mountains.
Deposition of ocean sediments built mountains as oceanic plates eroded at a divergent boundary.
Subduction of an oceanic plate at a convergent boundary caused mountains to form from uplift and rising magma.
Which statement describes a challenge of using geothermal energy technology?
Geothermal energy technology has a limited supply of energy.
Geothermal energy is not accessible in certain areas of the world.
Geothermal energy is not available during certain times of the year.
Geothermal energy technology harms the environment due to drilling in the ground.
