Substitution Mutation - A mutation that exchanges one base for another. For this example substitute A with G which will result in this sequence:
GCTGGTCGGCTG
Deletion Mutation - A mutation in which a section of the DNA is cut or lost.
GCTAATCGGCTA -> GCTCGGTA; section AAT was deleted
Insertion Mutation - Extra base pairs are inserted into a new place within the DNA
GCTAATGCGCGGCTA - GCG was added after AAT
Hope this helps!

Explanation:
Multicellular orgainism are composed of one of more cells differentiating to take on specialized functions.
A(n) <u>gene</u> is a sequence of organic nitrogen base pairs that codes for a polypeptide or a protein.
What is polypeptide?
Peptides are made up of short chains of amino acids joined together by peptide bonds. The word "peptide" comes from the Ancient Greek word "peptós," which means "digested." Oligopeptides, which comprise dipeptides, tripeptides, and tetrapeptides, are chains of fewer than twenty amino acids.
A polypeptide is a peptide chain that is longer, continuous, and unbranched.
Therefore, along with nucleic acids, oligosaccharides, polysaccharides, and others, peptides belong to the large chemical families of biological polymers and oligomers.
A protein is a polypeptide that has more than 50 amino acids, on average. A protein is made up of one or more polypeptides that are structured in a biologically useful manner. Proteins are frequently coupled to other proteins, other macromolecules like DNA or RNA, or complex macromolecular assemblies.

Answer:
c. The current changes are happening much faster than past changes.
Explanation:
This is correct because the earth's atmosphere is warming at an exceedingly high rate. This is due to the rise in amounts of carbon dioxide in the atmosphere among other factors. If the current trends were a representation of Earth's natural climate cycle then they would not be as high as they are now.
Have a great day. I assure you this is the correct answer. Let me know if you have any questions on this topic.
