Answer:
In order to propose a hypothesis, there is a need to first see the function of gills in fishes. The gills of fishes comprise blood vessels that exhibit inherited tendencies of getting oxygen out of the water, which was consumed by fishes from their mouths. These gills also comprise thin walls, and when water moves over these walls of blood vessels, the oxygen from water moves into the blood, and then this oxygen-enriched blood goes to various organs.
Thus, one of the hypotheses in the given case, can be the number of blood vessels, which are found in the gills of the mentioned freshwater fish to be higher in comparison to the blood vessels found in the normal fishes, and apart from this, the surface area of the thin walls, which are found in the gills is also more in the new species of freshwater fish.

Answer:
Prokaryote: lack of membrane-bound nucleus, DNA in cytoplasm, single circular chromosome
Eukaryote: Membrabe-bound nucleus, DNA inside nucleus, multiple chromosome.
Explanation:
Prokaryotes are one of the two domains, which consists of organisms that do not possess a membrane-bound nucleus. Due to this fact, the genetic material (DNA) of prokaryotic organisms like bacteria is found located in their cytoplasm. The DNA is found as a single circular chromosome in a region called NUCLEOID.
On the contrary, eukaryotes are the second domains of organism characterized by their possession of a membrane-bound nucleus that houses their genetic material (DNA). All the DNA of an eukaryotic organism like plants, animals etc. are found inside its NUCLEUS. They are made up of multiple linear chromosomes.
