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
When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it. This is known as a trophic cascade. The results of these trophic cascades can lead to an ecosystem being completely transformed. The impacts trickle down through each level, upsetting the ecological balance by altering numbers of different animal species, until the effects are finally felt by the vegetation.
The horse and mouse are endotherms among them rat will have high mass-specific metabolic rate.
The shark and fish are endotherms among them fish will have high mass-specific metabolic rate.
Explanation:
The endotherm (heat requires in them to maintain internal temperature of the body) organism have high metabolic rates to maintain homeostasis, this requires the large amount of energy. Smaller animals have the greater surface area to volume ratio, hence more heat loss and higher metabolism. In larger animals body volume increases, surface area increase is also very slow, hence less heat loss and lower Metabolic rate. Smaller animals exchange oxygen to tissues at a high rate.
Same goes with ectotherms the larger the animal the smaller is the metabolic rate. During winters their activity slows down as they cannot adjust with the temperature of the surrounding.
However metabolic rates of ectotherm and endotherm cannot be compared.
The intestines, I believe.
