The answer is Protista.
The dichotomous key is used to identify the taxonomic category of an organism. So, if we start with statements from the beginning, and discard the possibilities, we can put the organism into some taxonomic group.
Accordingly, we know that a stentor has a nucleus, so it must be eukaryotic. Among the Eukaryotes, it could belong to the kingdom of Protista, Fungi, Plantae and Animalia. Since it is unicellular organism and lives only in the water, it could belong only to the kingdom of Protista

<span>the base sequence of DNA is conserved during replication
through complementary base pairing. The first step of this process is to unwind the DNA's double helix. To do that is necessary the enzyme helicase break the hydrogen bonds between the nucleotides. These results in two strands that can become a template to use for replication. After that the enzyme DNA polymerase will form </span>hydrogen bonds with the nucleotides of the template DNA and new nucleotides, adenine will bond with thymine and
guanine will bond with cytosine.
The replication process has produced a new DNA molecule by using the original strand as a template and the new strand formed which is identical
