1

Some scientists study asteroids that could potentially impact Earth. Which mechanism could be used to best protect against this type of possible natural hazard?

1

Which set of answers is correct to label the diagram below?

1

The student observes that the shorter straws produce sounds with a higher pitch. Which set of information identifies and explains the characteristic of sound that the student observes?

1

The student wants to investigate how sound waves from the straw horn interact with different materials. Which wave property should be tested, and which method should be used to test it?

1

1

Which word or phrase in the parentheses forms the conclusion that is best supported by the maps?

The scratches on the bedrock suggest that the (landmasses / oceans ) were once connected nearer to the South Pole, and the ice flowed from ( several different locations / a central location / low latitudes to higher latitudes ).

1

A student builds a simple guitar using rubber bands and a cardboard box. Plucking the rubber bands results in sound waves. Which step would best help the student investigate the effect of changing the resonance of the sound waves?

1

Acid rain occurs when chemical pollution in the atmosphere reacts with atmospheric chemicals. This type of pollution is mainly released by burning fossil fuels to generate electricity, to power behicles and heavy equipment, and to run industries such as manufacturing and oil refineries.

Pick the phrase in each set of parentheses to correctly explain one way humans could reduce the impact of acid rain on Earth's ecosystems.

Increased ( use of public transportation / recycling of metals / water conservation measures / consumption of farmed seafood ) would reduce the impact of acid rain by reducing ( the amount of pollutants released by vehicles / reliance on nonrenewable resources / the pollution of water sources / the effect of pollution on aquatic ecosystem ).

Part A: Pick the word or phrase in each set of parenthese to correctly complete the statement about the process of mitosis.

Mitosis is a form of ( sexual / asexual ) reproduction that produces daughter cells with genetic information tht is ( identical to / modified by / different from ) the parent cell.

1

A model of mitosis is shown below beginning with the prophase stage. Pick the letter sequence of the cell stages that is the correct order of the steps of mitosis. Some cell stages may be used more than once and some may not be used at all.

1

Pick a word or phrase in each set of parentheses to describe the most likely effect that the opening in the paper will have on the light waves.

The light waves will be diffracted by the opening in the paper, causing the light waves to ( cancel out / come together / spread out ) and appear ( brighter / dimmer / equally bright ).

Using the table above, answer the next two questions.

The student strikes the 45-cm lid to produce a sound. If the student wants to produce a higher-pitched sound, which method should the student most likely use?

1

Which sound wave characteristic changes the most between each trial?

1

Planaria are flatwoms that reproduce asexually. Catfish reproduce sexually. Which statement best compares planaria and catfish?

1

1

Arctic hares are adapted to live in cold environments such as the Arctic. Scientific studies indicate that human activities contribute to a rise in the average global air temperature, resulting in a decrease in Arctic snow cover. Which statement explains how the changing arctic environment will most likely affect the population of arctic hares in winter?

The Cretaceous-Tertiary (K-Pg) event occurred about 65.5 million years ago. The causes are not completely known, but over fifty percent of all plants and animals went extinct. Evidence shows that Earth experienced a massive heat event that triggered fires, volcanic eruptions, and earthquakes. These activities released large amounts of debris into the air. The debris blocked the sunlight and caused Earth’s surface temperature to become much cooler.

Which type of organisms would have most likely survived this event?

1

Select below all that would apply.

1

Pick a word in each set of parentheses to best describe the movement of the tectonic plates in the diagram.

The tectonic plates move across Earth's surface due to ( convection / conduction / radiation ) from materials in Earth's ( core / mantle / crust ) layer.

Wind turbines transform wind energy into electricity. Using wind for energy is one way to replace the use of fossil fuels and other energy sources similar to fossil fuels. However, wind turbines can be dangerous to birds and produce noise pollution. The diagram shows the levels of sound heard in a town with turbines spaced at different distances from the town.

Part 1: Choose a claim that describes the relationship between wind turbines and human dependency on the use of nonrenewable resources.

Part 2: Choose a supporting statement that best defends the claim.

You will select one claim AND one supporting statement:

1

In some windy locations, a group of wind turbines may be built near each other. These are known as wind farms. Which pair of statements best describes a disadvantage and an advantage of building a wind farm instead of a single wind turbine?

1

Classify the structural/functional similarities between the pair of organisms as analogous and/or homologous. Check ALL that are correct
