Eventually these organelles leave the cell and a mature erythrocyte is formed. RBCs last an average of 120 days in the bloodstream. When RBCs age, they are removed by macrophages in the liver and spleen. A hormone called erythropoietin and low oxygen levels regulate the production of RBCs. ...
Carbon dioxide is the main gas we exhale. It is produced by all cells in the body during the process of cellular respiration, which cells use to make energy. The body must transport carbon dioxide to the lungs to get rid of it.Answer and Explanation: Carbon dioxide is transported in the ...

They draw liquid hydrogen and oxygen from the ET at an amazing rate, equivalent to emptying a family swimming pool every 10 seconds! The fuel is partially burned in a pre-chamber to produce high pressure, hot gases that drive the turbo-pumps (fuel pumps). The fuel is then fully burned ...
A rocket engine is throwing mass in one direction and benefiting from the reaction that occurs in the other direction as a result. This concept of "throwing mass and benefiting from the reaction" can be hard to grasp at first, because that does not seem to be what is happening. Rocket ...
Once the carbon dioxide is removed from the water, it still needs to be disposed of, as with other carbon removal processes. For example, it can be buried in deep geologic formations under the sea floor, or it can be chemically converted into a compound like ethanol, which can be used ...
In Southeast Asia, biogas is then usually used for electricity generation, for example, by selling it to the grid. Biogas contains a mixture of various gases, usually methane, carbon dioxide and other gases. When the carbon dioxide and other gases are removed from the biogas, you get ...
