Answer:
An atom consists of protons, electrons, and neutrons.
Explanation:
The atom of an element is its smallest indivisible particle that retains its chemical properties. Atom is the fundamental and basic unit of matter.
The structure of an atom is made up of a positively charged PROTON, a neutrally charged NEUTRON (both contained in the nucleus) and a negatively charged ELECTRON that surrounds the nucleus. These three particles are called sub-atomic particles. The arrangement and number of these sub-atomic particles determine the properties of the atom.

Answer:
This question lacks options, however, it can be answered based on general understanding of the topic
The answer is SUBSTITUTION MUTATION
Explanation:
A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.
Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).
This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.
