In batch fermentation, substrate is added all at once at the beginning of the process, and no more is added during the run. The product is generally not siphoned off during the fermentation process but is harvested once the fermentation is complete.

One common method to separate mud from bore water is by allowing the water to sit undisturbed in a settling tank or container. The mud particles will gradually settle at the bottom, and the clearer water can be carefully decanted or siphoned off from the top. Filtration systems or centrifugal separators can also be used for more efficient separation.
Normal "main sequence" stars fuse hydrogen into helium during most of the star's life. The core of a star gets so hot that the hydrogen atoms begin to fuse together. As hydrogen only has 1 proton when if fuses with another hydrogen atom it has 2 protons so has become helium.
Breathing, or pulmonary ventilation, is the process of exchanging air between the atmosphere and the lungs, and includes inspiration (inhalation), and expiration (exhalation). The movement of air into the lungs is dependent upon pressure gradients and the process is based on Boyle's law, which states that the pressure of a gas is inversely proportional to the size of its container. So in simple terms, if you have a certain volume of gas in a container, if that container were to get larger, the pressure inside would be reduced. Likewise, by decreasing the container size, the pressure increases. Using that example, the lungs are the container. By changing the size of the container, the pressure inside increases or decreases proportionally. During normal breathing, the diaphragm and external intercostal muscles contract to expand the lungs (our container), causing the pressure to decrease. When that pressure becomes lower than the atmospheric pressure, the air will move into the lungs (if you have ever siphoned gas its the same idea). As it moves into the lungs, it gets warmer, becomes moist, and expands. During expiration (exhalation), the diaphragm and intercostal muscles relax, causing the cavity size to reduce, which causes the pressure to increase. When that pressure becomes greater than the atmospheric pressure (outside), the air is forced out of the lungs.
Sand and gravel can be separated by simple screening - sifting through a screen that will allow the finer sand particles to pass through, while retaining the larger gravel particles on the screen.

No
Water can be siphoned uphill without a pump by creating a vacuum in the siphon tube, which allows atmospheric pressure to push the water up the tube against gravity.
you can but it would be easier to drain it from the bottom
NO it can not as there is a check valve located in the filler neck.
Siphoned refers to the process of drawing liquid through a tube by creating a pressure difference between two points. This allows the liquid to flow from a higher point to a lower point without the need for pumping.
Methane is commonly burned at landfills. It is not siphoned; it is a byproduct of decomposing materials inside the landfill. Since methane is lighter than air, it rises from the ground. Burning it keeps the landfill safe and is a great source of energy.
Some at the very top is siphoned out when you start to unscrew it.
To prevent water from being siphoned back into your plumbing system through an outdoor faucet, you can install a backflow preventer. This device stops water from flowing in the wrong direction and helps maintain the safety of your water supply.

An airplanes cabin is pressurized with what is called "bleed air", air that is siphoned out of the compressor chamber of the engines. The air is directed through duct work to the belly of the plane, where it is filtered, cooled, then circulated in the cabin. Equal amounts of air are siphoned off each of the engines. If one engine should fail, the other engine(s) provide the bleed air.
skimming, as in skim milk, is just skimming the cream off the top of the milk when it separates, with a spoon. Or the milk can be siphoned off the bottom of the tank.
