Q: - The cells of the lung hold the air - They take in the air and remove the Oxygen - They inflate and all the bad air leaves through the mouth - They do it all over again. What might be the first step of the process?
A: They expand to take the air in

Q: - The energy from the sunlight causes an enzyme in the plant to break apart the water - The water breakes into oxygen, hydrogen, and electrons - Hydrogen, along with electrons energized by light, converts NADP into NADPH - Oxygen diffuses out of the plant as a waste product of photosynthesis - What might be the first step of the process?
A: Sunlight hits chloroplasts in the plant

Q: - That bacteria begins to grow and reproduce inside the cells - The dividing bacteria begin to make toxins - Those toxins damage your cells - Disease symptoms may begin. What might be the first step of the process?
A: Someone is infected with bacteria

Q: - The water combines with carbon dioxide in the air to form carbonic acid - As the acid is formed, the iron starts to dissolve - Some of the water breaks down into hydrogen and oxygen - The free oxygen and dissolved iron bond together - They form iron oxide, which is rust - What might be the first step of the process?
A:
Water comes into contact with something made of iron
