• F travels in straight lines and reflects from the surface of the mirror

• G refracts in the glass of the mirror and is spread out all over the room

• H enters the mirror and changes direction when it is refracted by the back of the mirror

• J travels through air and does not change its direction in air

A science class has an aquarium in which fish and aquatic plants are growing. How is carbon dioxide directly involved in the survival of organisms in the aquarium?

• The fish must absorb carbon dioxide through their gills for energy.

• Both the plants and the fish need carbon dioxide to make their own nutrients.

• The plants need carbon dioxide to make sugar.

• The plants release carbon dioxide into the water to control the water temperature.

• F Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

• G Heat from the sun causes clouds in the area to gather over the ocean and form one large cumulonimbus cloud.

• G Heat from the sun causes clouds in the area togather over the ocean and form one large cumulonimbus cloud.

• J Light from the sun causes ocean water to reflect water vapor into the air and gather over the ocean into a cumulonimbus cloud.

• A Stir the liquids, let them settle, and then identify the bottom layer as water

• B Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water

• C Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water

• D Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water

Which statement best describes the processes of weathering and erosion?

• F Weathering and erosion are directly responsible for the breakdown of any type ofrock into smaller particles and the carrying away of the loose sediments.

• G Weathering and erosion are directly responsible for depositing loose sediments on the bottom of the ocean, forming layers of sediment.

• H Weathering and erosion are directly responsible for the amount of water in a river that transports sediments to the sea.

• J Weathering and erosion are directly responsible for the transportation, deposition, and compaction of loose sediments on the seafloor.

Based on this information, what is most likely an advantage of the bony fish tail fin over the shark tail fin?

• It is easier for a bony fish to change direction quickly since muscles control the movement of the tail fin.

• The bones in the tail fin help a bony fish sink to lower depths in the water when searching for food.

• The flexible tail fin is fanned by the water, so a bony fish uses less energy to swim.

• The thin spines of the tail fin prevent a bony fish from being seen by larger predator fish.

What is the athlete demonstrating in the picture?

• Doing work by pushing the ball and changing its motion and position

• Changing the position but not the motion of the ball

• Doing work by pulling the racquet and changing the ball’s position but not its motion

• Changing the position and motion of the ball without doing any work
