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.

I think the answer is capital
Blood type is not a concern when transfusing plasma from person to person because the plasma does not contain red blood cells. when things such as organs or blood are given to people (contain red blood cells), they must match the blood type of the person receiving these things so that there is a smaller chance of the person rejecting the organs, blood, etc. due to plasma not having red blood cells, we do not need to worry about the body rejecting it.
