<span>While alien genomes may be constructed by completely different molecules (for example, silicon based life forms are a possibility rather than carbon) it is logical to assume that all life forms would have some sort of protective mechanism to prevent the degradation of DNA during replication. Essentially, to prevent mutations and rapid aging, DNA, alien or otherwise, would have some types of telomeres. They might either be long chains of repeated or irrelevant code or molecules that would not be easily corrupted.</span>
The answer would be B. Cats.
Cats are the most advanced organisms between the options thus have the greatest amount of cell specialization.
Organelles float around in the cytoplasm.
Bedrock striations. Striations are marks or lines in the bedrock caused through glacial movement
Most likely a silent mutation. Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype because the same amino acid is produced regardless of the change in the nucleotide sequence by the mutation.
