Quite a few fit that description (including water, carbon dioxide, borane etc.)
Amino acids.
Phosphate is a chemical group with the formula R3PO4 where R represents a generally reduced chemical group such as a methyl group or a Hydrogen atom for covalent Phosphate compounds and PO4(-3) for the Phosphate anion with 4 Oxygen atoms covalently bonded to a central Phosphorus atom with 3 negatively charged electrons shared between the four Oxygen atoms. Phosphide is an anion where Phosphorus has three electrons bound to it. It is an extremely strong base in contrast to Phosphate which is a significantly weaker base. Phosphide is also a very strong reducing agent.
No it is not because Phosphorus is never found free in nature, it is widely spread in combination with minerals. Phosphate rock, which contains the mineral apatite, an impure tri-calcium phosphate, is an important source of the element. Large deposits are found in Russia, in Morocco, and in Florida, Tennessee, Utah, and Idaho. You can mine it in many many places, and the gross part is that you can extract P from Urine.
Snow leopards are loners and never in a group.
It is NEITHER at standard temperature and pressure. The pure element (which is practically never found in a pure form) is a white/yellow waxy solid, or a red amorphous solid, or a black powdery solid. But it does form both liquid and gaseous compounds at room temperature.
Amino acids.
The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
I'm unclear what you mean. Cysteine is an amino acid and never found in DNA. Do you mean cytosine? If you do, cytosine is not directly linked to phosphates - rather cytosine is linked to deoxyribose which in turn is linked to the phosphate group.
Polar if it is bent.

One group is products that were never meant to be ingested or inhaled, the other group contains products that can be ingested in small quantities, but which are harmful if taken in large amounts.
The 'nucleic acid' part comes from early observations1(869) that there was a weakly acidic product in extracts of the nucleus from cells in wound pus. At this time, it was never suspected that DNA would contain the genetic information of the cell (it was assumed that proteins would do that).'Deoxyribo' means 'Deoxy-ribose', since all nucleotides (the units that make up a DNA/RNA strand) contain a ribose sugar, which attaches to the base (adenine, thymine, cytosine, guanine or uracil) and to a phosphate group. In DNA, the ribose sugar is missing an oxygen from a hydroxyl group (on carbon 2), giving it its name deoxyribonucleic acid.

are the other molecule which are never touched in the particular organ.

He never was in a group.
