1. The space exploration program has hired you for advice on how to keep astronauts healthy in the space shuttle. How can the program's doctors make sure the astronauts’ bodies work well enough to exercise in space?

A. The doctors could make sure that the astronauts’ bodies can make enough energy by getting enough sleep.

B. The doctors could make sure the astronauts’ stomachs are getting the molecules they need from food and air.

C. The doctors could make sure the astronauts’ cells are getting the molecules they need from food and air.

D. The doctors could make sure the astronauts’ cells are getting different types of molecules from food.

2. Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?

A. It would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together.

B. It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.

C. Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.

D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

3. Doctors tested a patient and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. Will this patient be able to exercise normally?

A. Yes, the glucose and oxygen molecules can react together to release energy for the body to function.

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; in cells, only amino acids can react with oxygen to release energy.

D. Yes, as long as his cells have glucose, they don’t need anything else to release energy for the body to function

4. Some problems with the digestive system make it very difficult for the body to digest enough food. Why would it be harder to exercise when you have a digestion problem like this?

A. You would not be able to sleep, which would make you too tired to exercise.

B. Your cells would have molecules from air, but would not get enough molecules from food.

C. You would need to breathe in a lot more air because your body would have fewer molecules from food.

D. You would not get any of the molecules your cells need to exercise.

5. The test report above shows the level of molecules in different parts of the patient’s body. How would you expect this patient to do on an exercise test? (use the image only for this question!!!)

6. Two soccer teams, the Bears and the Panthers, played games at the same time in two different locations. The Bears game was played at sea level, where there is a normal amount of oxygen. Before their game, the players on the Bears ate a lunch of mostly starch. The Panthers game was played at very high altitude, where there is less oxygen. The players on the Panthers ate a lunch of starch and protein. Which team probably did better in their game? *

A. The Bears probably did better because their cells released energy from oxygen reacting with glucose, which was broken down from starch in the digestive system.
B. The Panthers probably did better because their cells released energy from breaking down protein in the digestive system, which then combined with oxygen in cells.
C. The teams did equally well because their digestive systems just need to break down starch into glucose for cells to release energy.

D. The teams did equally well because glucose from starch can react with oxygen or proteins to release energy.

7. A student thinks that the human body only works properly when cells are getting molecules from food and molecules from air. Is the student correct?

A. Yes, the body only works when cells get molecules from food and molecules from air.
B. No, the body only works when cells are getting molecules from different types of food.
C. No, the body only works when the lungs get molecules from air, and the stomach gets molecules from food.

D. No, the body works as long as cells are making all the molecules they need.

8. Stella’s respiratory system is not working well. Why is this a problem for her ability to exercise?

A. Her respiratory system will not be able to break down molecules from air into oxygen.
B. Her cells will not work well when they have low levels of oxygen.

C. Her digestive system will have to work twice as hard to get the same amount of energy from glucose molecules.

D. Her cells will not work because molecules from air will be too large for her body to use.

What do you think makes an argument stronger? Explain 1- 2 things that would make an argument stronger and more believable?

(This is for science so try to make it science-related.)

Before humans ever ventured into space, we fantasized about visiting—and even living on—other planets. As technology continues to develop, it may one day be possible for humans to call planets other than Earth's home. Space scientists have several possible Earth-like planets and moons insight, but one that is of high interest is Kepler-186f, a planet 500 light-years away. It orbits a star much like the Sun, and it orbits in a habitable zone: it is far enough from the star to allow for the pooling of water (if it is present) on the planet's surface.

Is being in a "habitable zone" enough to say the planet is habitable for human life? What characteristics would an Earth-like planet need to have to support life? What challenges would we face traveling to and colonizing Kepler-186f or other Earth-like planets outside of our solar system? Do you think scientists should spend time looking for Earth-like planets before we have the technology to visit them? Why or why not? PLEASE HELP ME!!! :((
