How does plant growth effect the carbon-oxygen cycle? What happens when you breathe in water vapor? What would most likely happen to the carbon cycle if there were no more plants on Earth? How does carbon dioxide enter a plant? What happens to the nitrogen we inhale? How do flowering pla...
What happens when a plant doesn't get enough oxygen? What happens when hot and cold air meet? When air expands, what happens to the air temperature? What happens to the nitrogen we inhale? What would most likely happen if there were no condensation stage in the water cycle? What happens ...
Researchers are looking into new potential treatments. With hyperbaric oxygen therapy (HBOT), you have daily sessions to inhale pure oxygen in a chamber with air pressure that’s 1.5 to 3 times higher than normal. This boosts theoxygen levelsin your blood to help speed tissue healing. In a ...

If you do the math, you'll see that a person needs about 150 cubic feet of pure oxygen per day. There's 320 cubic feet of pure oxygen in the freezer. People are OK with oxygen concentrations down to 10 percent or so, so there's enough oxygen to last for about a full day in a...
Well, ifyoudesignedyourlectins that way and each species did the same for theirs, what would be left to eat on this planet? We would all be toxic to one another! On the flip side, being edible to everyone is having the pendulum swing too far in the other direction. If the berries on...
The groundwork for finding krypton was laid in 1785, when Henry Cavendish observed that the air contained a fraction that was neitheroxygennornitrogen. It turns out that several elements that came to be known as thenoble gaseswere present in this fraction, and scientists began to identify these...
I held my breath for a while and then had to exhale and—as you might expect—inhale in turn. The inhalation brought the damp cloths tight against my nostrils, as if a huge, wet paw had been suddenly and annihilatingly clamped over my face. Unable to determine whether I was breathing ...
