Silicates is the answer to this.
Answer:
B. Mutation; C. Random genetic drift; D. Migration; F. Natural selection
Explanation:
B. Mutation: Mutations resulting from substitution, addition or deletions of a nucleotide in a sequence can alter the gene. This can be carried over a population and may be have deleterious effects or increase fitness in a gene.
C. Random genetic drift: It is a change in allele frequency that occurs by chance, usually in a small population and is carried over generations.
D. Migration: Involves the flow of a gene in or out of a population, and this modifies the allele frequency.
F. Natural selection: When fitness-promoting alleles are favored and carried over to the next generation.

Answer:
All atoms can be identified by the number of protons and neutrons they contain. The atomic number (Z) is the number of protons in the nucleus of each atom of an element. In, a neutral atom the number of protons is equal to the number of electrons, so the atomic number also indicates the number of electrons present in the atom. The chemical identity of an atom can be determined solely from its atomic number. For example, the atomic number of nitrogen is 7. This means that each neutral nitrogen atom has 7 protons and 7 electrons. Or, viewed another way, every atom in the universe that contains 7 protons is correctly named “nitrogen.”
