How does the energy of a roller-coaster cart change as the cart travels from the top of the roller coaster to the bottom? 

• The cart has greater kinetic energy at the top than it does at the bottom. 
• The cart has no energy at the top and more energy at the bottom. 
• The cart has less potential energy at the top than it does at the bottom. 
• The cart has potential energy at the top that is transformer to kinetic energy as it moves to the bottom.

How can simple machines make work easier? 

• by decreasing the force needed to complete the task. 
• by increasing the friction between the machine and the object. 
• by adding more work on the object than originally applied
• by removing the force of gravity

Why does the troposphere experience the greatest amount of atmospheric pressure compared to the other atmospheric layers?

• It produces the ozone layer.
• It has the highest temperatures. 
• It contains a high concentration of gas particles. 
• It is the region in which weather occurs. 

Which explains why most of the rain that falls comes from the ocean?

• The majority of evaporation takes place over the ocean. 
• The majority of precipitation takes place over the ocean. 
• Most rivers deposit freshwater into the ocean. 
• Most clouds form near or over the ocean.

A sea breeze blows from the ocean toward the shore. Why does this occur? 

• High pressure over the lands causes a downdraft to occur. 
• The tide carries the wind to the shore as it moves back and forth. 
• Conduction of heat from the warm water produces wind from the ocean. 
• Air over land heats faster than air over water, which causes convection.

Which two organisms contain chloroplasts and eyespots? 

• Amoeba and paramecium
• Paramecium and volvox
• Volvox and euglena
• Euglena and amoeba

How do a paramecium and an amoeba obtain food to live? 

• A paramecium and an amoeba both use contractile vacuoles to capture food. 
• A paramecium and an amoeba both make their own food through photosynthesis. 
• A paramecium collects food into an oral groove, while an amoeba uses pseudopods to surround food. 
• A paramecium uses pseudopods to capture food, while an amoeba uses chloroplasts to make its food.

Tina observed a cell under a microscope. She concluded that it was a plant cell instead of an animal cell. Which structure helped her come to this conclusion? 

• She saw a vacuole, which animal cells lack. 
• She saw a  nucleus, which animal cells lack. 
• She saw a chloroplast, which animal cells lack. 
• She saw a cell membrane, which animal cells lack.
