Answer:
1. Substitution
2. Insertion and deletion
3. Amino acids can have more than one codon that signals for it. Due to this, some substitutions don’t affect the protein at all.
Explanation:
1. Substitution sometimes isn’t as impactful. It can result in the same amino acid to be signaled as the original one since amino acids can have more than one codon signaling for it.
2. Insertion and deletion are also known as frameshift mutations. This is because they shift the codon spots by adding or deleting a nucleotide.
The answer to this is Quaternary.
The surface area to the volume ratio gets smaller as the cell gets larger. If the cell grows beyond a certain limit not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
Hope that helps
