When ethanol is oxidized to acetic acid, two protons and two electrons are also produced. Read More Breathalyzers FAQs How long after drinking can you pass a breathalyzer test? This depends entirely on your metabolism. Some digest and pass alcohol faster while some are slow. In general, ...
X-rays are essentially the same as gamma rays, but their origin is different. Where gamma rays come from inside the nucleus of an atom, X-rays come from processes outside the nucleus. X-rays come from a change in the electron structure of an atom and are mostly machine-produced. They ...
Just like with a photograph, the result of this process is a piece of film that has recorded the incoming light. However, when you develop the holographic plate and look at it, what you see is a little unusual. Developed film from a camera shows you a negative view of the original scen...

common phyla in deep dentin carious lesions, andLactobacilluswas the most abundant genus in only 25% of the carious lesions20. There is increasing recognition that dental caries is caused by the imbalanced microbiota in the biofilm, also known as dental plaque, rather than by a single pathogen...
Overall, the space surrounding the cell is going to have a charge that’s relatively more positive than the spacewithinthe cell. So the charge inside this cell will be negative by comparison. It’s a state of being that scientists call the cell’sresting membrane potential, or RMP. ...
The inside fluid is rich in potassium, a concentration about 20 times higher inside the cell than outside. There are large negatively charged proteins inside the cell that are too big to move across the membrane. They give the inside of the cell a negative electrical charge compared to the ...
One is a special device called Bio-KES which converts ethylene into carbon dioxide and water using ultraviolet light. Ethylene causes plants to ripen and eventually spoil. A device like Bio-KES, used in food storage units and display cases, could help increase the shelf life of produce, ...
