Yes
This a very simple answer. They use their tentacles to push themselves through the water. No this is actually wrong. The squid uses its siphon to propel itself through the water. How it does this is it fills its mantle with water then the squid pushes it out through the Siphon.
Squid respire via the mantle; water is pulled in, pushed across the gills, and then expelled via the exhalent siphon of the mantle.
The pressure sandblaster will be quicker, but I'm not sure if the siphon sandblaster will blast the rust off the metal as proficiently as the pressure blaster. It would likely not clean the metal as well.
Most of the useful nutrients are dissolved or suspended in groundwater. Capillary action draws this water into the roots and up the plant, as moisture transpires from the leaves of the plant, somewhat like a siphon. Capillary action is a consequence of the surface tension of water. Once the water is in the cells of the plant, its cellular processes extract nutrients in various ways.
Install an inline canister at the bend and the siphon can draw water through it to an elevation above the water source. Stop the siphon flow with a shutoff valve and empty a small amount of the water from the canister and then close it back airtight. When the siphon flow valve is opened the weight of the water in the long leg of the siphon can draw the air out and once the line is purged, the canister is ready to be emptied again. AUTOSIPHON (R) company has designed one valve which can do this.
Add some water, then siphon it out.
Yes
The incurrent siphon is a tube that water flow into which allows respiration, reproduction, locomotion and feeding. Locomotion is achieved by expulsion of water.
The clam has two siphons. The excurrent siphon (which expels water and waste out of the clam) and the incurrent siphon (which brings oxygen and food and water into the clam).
Probably, but why bother? Just buy a pump or siphon ready made.
If the end of the hose is running in a pool of water, yes
No it's water released out of the Siphon.
it doesn't
Water enters the mantle cavity through an incurrent siphon, and exits the mantle through an ex current siphon. This is a normal aspect of biology.
A shipon is like a filter it washes water in a out (like gills) for the airway. The siphon also helps the squid move faster.
