5th Released EOG (22-44)

Amy and Belle were discussing ways to help the fox population. There is a

grassland ecosystem nearby with these characteristics:

• -There are few trees, shrubs, and ferns, and no berry bushes in the

grassland;

-the river does not flow through the grassland;

-some rabbits are found in the grassland, but because there are few

hiding places, the rabbits are easily caught by hawks.

Amy states that the remaining foxes should be removed from the forest and taken

to the grassland. Belle disagrees. Which student is correct?

• Amy, because there will be more food for the foxes in the grassland

  ecosystem

• Amy, because there is no water, and therefore no toxin present in the

  grassland ecosystem

• Belle, because there will be fewer predators for the foxes in the grassland

  ecosystem

• Belle, because the foxes will not have the resources they need to survive in

  the grassland ecosystem

Scientists have found a way to remove the toxin from the river. What effect would this have on the berry bush population?

• The berry bush population would increase because there would be more

  foxes.

• The berry bush population would decrease because there would be more

  foxes.

• The berry bush population would increase because there would be fewer

  foxes.

• The berry bush population would decrease because there would be fewer

  foxes.

A scientist fills a beaker with a 100-gram sample from the river. She separates the toxin from the water to examine it more closely. She pours the liquid toxin into another container. How does this affect the weight of the water sample left in the beaker?

• It weighs the same because there was more water than toxin in the sample.

• It weighs less because the water sample is cleaner without the toxin.

• It weighs the same because the toxin is a liquid and has no mass.

• It weighs less because the toxin is a liquid and has mass.

• More clouds will form.

• Temperatures will be cooler.

• Temperatures will be warmer.

The map below shows the state of North Carolina. During the winter months, western North Carolina generally experiences more snow than eastern North Carolina. Which statement best explains this?

• Cool air from the ocean moves west across the state, allowing western North Carolina to experience snow.

• Warm air from the ocean moves west across the state, allowing western North Carolina to experience snow.

• Warm, dense air pushes from western North Carolina toward the north, allowing the region to experience snow, while cool air from the ocean cools down the atmosphere in the east.

• Cold, dense air pushes from the north toward western North Carolina, allowing the region to experience snow, while warm air from the ocean heats up the atmosphere in the east.

What role does the sun’s energy play in the process of transpiration in plants?

• The sun’s energy causes the moisture in plants to evaporate.

• The sun’s energy causes the moisture in plants to drip off the leaves.

• The sun’s energy causes the moisture in plants to return to the ground.

• The sun’s energy causes the moisture in plants to stay in the leaves until it rains.

The illustrations below show three different types of muscle cells in the human body. (Refer to the diagram) Which statement do the illustrations support?

• A. Muscle cells are made up of connected muscle tissues.

• B. A muscle is an organ made up of only one type of muscle cell.

• C. Different types of muscle cells make up different types of muscle tissue in the human body.

• D. Different types of muscle cells make up the same type of muscle tissue in all parts of the human body.

What do the digestive system and circulatory system of the human body have in

common?

• They work together to help give the body the ability to speak, smell, and breathe.

• They work together to give cells the nutrients needed to produce energy.

• They work together to reduce waste and keep the body clean.

• They work together to pump blood throughout the body.
