Bob passes by a building every day on his way to school. He notices that the rock used to build the walls of the building is different from the rock used to build the steps. How might energy have played a role in the formation of the different types of rock?
Energy from different sources leads to different types of rock. Energy within the Earth melts rock into liquid rock, but energy from the sun causes rock to wear down into small pieces of rock.

No, igneous rock forms beneath the Earth's outer layer due to energy from within the Earth, but sedimentary rock is only on the Earth's surface.
Yes, if sedimentary rock is exposed to the sun's energy on the Earth's surface for a long enough time, it can melt into liquid rock and form igneous rock.
Yes, if sedimentary rock moves beneath the Earth's outer layer and is exposed to energy from within the Earth, it can melt into liquid rock and form igneous rock.

Yes, the energy from within the Earth can cause the igneous rock to break into small rock fragments that form sedimentary rock.
No, sedimentary rock forms on the Earth's surface because the sun's energy causes the rock to wear down, but igneous rock beneath the Earth's outer layer is not exposed to the sun's energy.

A patient has been eating healthy foods, but his digestive system is not doing what it usually does. Can this patient still exercise normally?
A Yes, as long as he can still breathe, his cells will have all the molecules they need to release energy.
B No, his digestive system is not breaking down oxygen into molecules small enough to get inside his cells.
C No, molecules from food are not combining together to be large enough for his cells to use.
D No, molecules from food are not getting broken down small enough to get inside his cells.
If a person is breathing normally, which of the following could prevent him from using his body to exercise normally?
A Not getting enough sunlight, because cells need sunlight to function
B Not getting enough sleep, because the body only makes energy for exercise while asleep
C Not eating enough food, because cells need molecules from both food and air to work
D Nothing, because he would be able to exercise normally as long as his cells are getting molecules from the air
Raoul ate a meal of oats before seeing his doctor. Oats are made of mostly starch molecules. Raoul feels tired, so his doctor gave him a test and found that Raoul’s cells contained glucose molecules, but they did not contain enough oxygen molecules. Does this explain why Raoul feels tired?
A No, something else must be wrong because his cells have all the molecules they need.
B Yes, his digestive system is breaking down starch molecules, but his respiratory system may not be working properly.
C Yes, his respiratory system is working, but his digestive system is not getting energy from combining glucose molecules.
D Yes, his digestive system is working, but his respiratory system is not breaking down oxygen, so his body stopped making energy.
Doctors tested a patient to find out what molecules were in his cells. His cells contained normal levels of glucose molecules and amino acid molecules, and low levels of oxygen molecules. Will this patient be able to exercise normally?
A Yes, his body is working properly enough to exercise.
B No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.
C No, his body systems are working, but he needs to eat different food; only proteins can react with glucose to release energy.
D No, his respiratory system is not working; his cells need oxygen to react with glucose, which releases energy.
Rico, a scuba diver, uses breathing gear to help him breathe air underwater. He always gets enough sleep and eats a good breakfast before a dive. What could happen if his breathing gear broke during a dive and he could not breathe as much air as usual?
A It would be difficult to swim, because his cells cannot work without molecules from air.
B It would not affect him because his cells are getting the different types of molecules they need from food to work properly.
C It would not affect him as long as he slept enough.
D It would not affect him because his body can function normally even if his cells do not have molecules from air.
The test report shows the level of molecules in different parts of the patient's body. What does this test indicate about how her body systems are working?
A Her body systems are working properly.
B Her digestive system is not combining molecules together.
C Her digestive system is not breaking down molecules from food.
Two teams of scientists hiked 10 kilometers to different study sites. Before their hike, the Valley team ate a lunch of mostly protein. The Mountain team ate a lunch of a mix of starch and protein, but hiked at high altitude, where there is much less oxygen. Which team probably had an easier time hiking?
A Both teams had an easy time hiking because their digestive systems broke down proteins into amino acids for cells to release energy.
B Neither team had an easy time hiking; the Valley team’s cells needed more glucose from broken-down starch for a reaction, and the Mountain team’s cells needed more oxygen from air.
C The Mountain team had an easier time hiking; their cells released energy from protein reacting with glucose, which was broken down from starch in the digestive system.
D The Valley team had an easier time hiking; their cells released energy from protein breaking down in the digestive system, which then combined with oxygen in cells.
An athlete thinks that she can exercise as long as she eats different types of food because her body just needs different types of food molecules to work properly. Is the athlete correct?
A Yes, her cells only work when they have molecules from different types of food.
B No, her muscles do not need molecules from food because all cells make all the molecules they need.
C No, all cells need molecules from food and molecules from air to work properly.
D No, only her stomach cells need food molecules to work properly.
Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal levels of amino acids, normal levels of oxygen molecules, and low levels of glucose molecules. Will this patient be able to exercise normally?

C No, her cells need glucose to react with oxygen to release energy.
D Yes, her cells just need oxygen to release energy.

Marisol has been chewing and swallowing her food, but her digestive system is not doing what it usually does. Why is this a problem for her ability to exercise?
A Her cells will not work well because molecules from her food are not being broken down small enough to get to her cells.
B Her body will run out of energy because molecules from the air are not being combined into larger molecules for the cells.
C Her respiratory system will have to work twice as hard to break down molecules from food.
D Her cells will not work well because the molecules from food will be too small for cells to use.
