The most common organisms with exoskeletons are arthropods which include insects (bees, ants), arachnids (spiders) and crustaceans (lobsters and crabs).
The cells will make some sort of reaction, there's no doubt about it. But for a bass I believe that their cells will stay the same or shrink over time.
Bass are strong fish and they usually do well when there's a change in conditions made in the environment. But it depends on what this river has in it and if it leads to bigger opened waters.
If there's a shortage of food sources for the bass it'll have to adapt quickly or it'll die from the predators in the area. If there isn't any places the Bass can lay their eggs (reproduce) its population will die in that river.
There also competition. In that river it could have socked eye salmon in it or catfish even pikes. So the Bass cells would stay the same.
Hope this helps
The fossil shows evidence of how animals lived on Earth in the past and shows history about animals that may be extinct now or have evolved since then, which would show development in the animal in the fossil.
In the cell, the function of the smooth endoplasmic reticulum is that it produce lipids, which are fats and oils. They also transport materials..
