Very good. All submarines have atmosphere control equipment.
Without breathing, the world record is 22min With air bottles (scuba diver) or in a submarine you can of course stay longer. In a submarine when you have enough supplies, you can stay virtually forever under water.
Systems of underwater mountains are called mid ocean ridges. They are larger than land mountains and have longer chains of them.
Manatees are not land-dwelling, they are water-dwelling mammals therefore their lungs are bigger so they can stay underwater longer.
No, not really. It may look like that because when you put your hair underwater it floats and looks like it is longer than how it is when it is dry.
They don't stay underwater longer than whales.
Whales, dolphins, and maybe a platypus.
yes dolphins can stay under water much, much longer than humans can --------------- lol yeah about 3 hours longer
"submarine" translates as "U-Boot" in German."atomic submarine" translates as "Atom-U-Boot""missile-launching submarine" translates as "Raketen-U-Boot" The newest German Boot is the "Typ 212" which uses hydrogen fuel cells that don't need air to run.This means that the length of time they can remain submerged is far longer than any atomic submarine can. They are far safer than the atomic submarines.
Most likely, the sub part of submarine means a sub (long thin sandwich, like a hot dog bun but longer) and the marine part means something like fish or seafood.
Only slightly longer than a ladybug I caught about 20 bees in my pool net. I put the net under water and could see them crawling around inside the net. After no longer than 60 seconds they were all dead. A bee can hold its breath underwater for about 60 seconds.
Cornelius Drebbel built the first workable submarine in 1620 using the 1578 plans of English mathematician William Bourne. The frame was constructed of wood, and it was wrapped with waterproof leather. It no longer exists.The first submarine called the "Turtle" was reportedly destroyed.
