Answer:
The chemical element which would be the most reactive with other elements is: D. helium, #2.
A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following:
- Tarnishing.
- Heat of combustion.
- Flammability.
- Acidity.
- Chemical reactivity.
Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.
Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.
The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.
Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.
In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.

Answer:
The correct answer is - substitution.
Explanation:
Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the DNA or RNA of an organism's genome.
In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.
