Explanation:
All the spheres of the earth are connected including the geosphere and the biosphere. The biosphere depends on the geosphere (the rocks and minerals of the earth) mainly for nutrients required for growth and for habitat.
Due to this connection, therefore, if the harmful substance was to enter the geosphere, it would negatively affect the biosphere. It could be from the fact that if mineral of the substance is absorbed or taken up by organism of the biosphere, they die. This would destroy ecosystems and hence reduce the biosphere (the living component of the earth)

Neon belongs to the group of elements on the periodic table called the noble gases. These are the most stable elements and they do not react with other elements.

- It requires a loss of two electrons to attain stability.
- Therefore, it is a more reactive element.
The genetic code is carried by the DNA molecule in most organisms. DNA is the store for hereditary information.
In eukaryotic cells, DNA is found in the cell nucleus, while in prokaryotes it is found in the nucleosome.
The genetic code is the triplets of nucleotides in DNA and RNA that define and direct which amino acid is used in protein synthesis.
The genetic code is expressed in 64 different triplet combinations that code for different amino acids. Three of these triplets are called non sense triplets or codons because they do not code for any amino acid. The rest are sense codons.
