wikipedia.org has the entire classification ladder defined for most plants animals and living creatures in general. Try looking there.
All elements and compounds can exist as a gas if heated sufficiently.
Members of Lego Universe live all over the world!
No, Hydrogen makes up approximately 75% of the universe's elemental matter
The periodic table does. If you mean the actual elements, nothing in the universe can contain all elements at once, since many are to unstable to be formed and exist while the others are being created.
No, because Vitani and Kopa don't exist in the same sub-universe. They both exist in the over-all The Lion King universebut Kopa does not exist in the movie universe wherein Vitani does and Vitani doesn't exist in the books wherein Kopa does.
The only word we can think of is "Universe". But if that's the one the question isfishing for, then its description is much too restrictive. The Universe is not only thetotality of all things that exist. It also includes all of the space in which they haveever existed or could exist, as well as all of the time in which they have existed,do exist, or will exist. Now that's a Universe.
The alien periodic table is a hypothetical concept based on the idea that elements could exist in unknown parts of the universe with different properties from those we know on Earth. It is not complete because our understanding of the universe is limited, and we have not discovered all possible elements or their properties.
All elements and all compounds do not exist as molecules. As examples, noble gases exist as individulal atoms and ionic compounds form lattices.
So far, no living beings - animals, plants, or whatever - have been confirmed to exist in other parts of the Universe. They may very well exist; we just haven't been able to research a sufficiently large part of the Universe from nearby.
The Big Bang created over 99.9% of the atoms in the current universe, but these are limited to Hydrogen and a little bit of Helium.Stellar fusion created most of the Helium and the elements from Lithium through Nickel and Iron.Supernova explosions created all the rest of the elements, including quite a few transuranic elements.
Without gravity, it is doubtful that the universe as we know it would exist at all. At the very least, galaxies, stars and planets would be unable to form. Worse still, without stars there would be no heavy elements and it is unlikely that life would exist.
