They take a gas that your body needs to get rid of (carbon dioxide) and exchange it for a gas that your body can use (oxygen). They also work with your heart to make sure your body has the oxygen-rich blood it needs to function properly. In this article, we will take a close ...
In this study, we evaluate the development of Baltic deoxygenation since 1970 by calculating the time series of the total amounts of oxygen, H2S and NH4below 65 m. We then calculate how much oxygen is needed to eliminate all H2S and NH4below this depth, define this as an oxygen debt, an...
Trees are essential to our survival . They are a major part of the process of photosynthesis . Photosynthesis is the process in which green plants use carbon dioxide to produce oxygen ,and oxygen is something all of us need . The fewer trees there are ,the more this affects our ability to...
A quick pause here to insert something about ‘aging’. We all know we need oxygen to survive. No discussion. But as we age, our ability to efficiently utilize oxygen slowly but steadily declines. And with this inevitable deterioration of our oxygen extraction systems comes our susceptibility to...
15. What is Mia likely to do right after she returns home? A. Watch TV. B. Send a message. C. Roast a chicken. 16. How did Bob get the sweater? A. His mother made it for him. B. His brother gave it to him...
These growing machines also need to integrate with the life support system to successfully exchange carbon dioxide and oxygen. So when can astronauts visit space's first salad bar? It might be a while as researchers work to understand and overcome the obstacles that space farming presents. Read ...
Water weekly or as often as needed to keep the soil moist, but not wet. Daily watering may be required during very hot summers – when in doubt, amoisture meteris your friend! 3. Root Rot Persistently wet soil hinders the transportation of oxygen to the plant’s delicate root system, ca...

Two observations. We need to start paying attention to dust. The drought in the the Southwest is starting to spawn dust bowl conditions. Masks of some sort may be the only protection, silicosis isn’t simply dirty, it is dangerous. In the 1930s visibility was so poor that people got lost...
“By studying these fossils, we can see how their shells have responded to changes in the environment, like temperature, salinity, pH, or oxygen. By studying the geochemistry preserved in their shells, foraminifera are excellent tools for showing the age and environment of a geologic deposit. Al...
