The decreased oxygen levels in the water will affect the respiration of the fishes. In order to cope up with the change, the fishes may migrate to a better place with higher levels of dissolved oxygen. This however does not relate to the process of natural selection as the fishes are still the same, genetically and phenotypically. Natural selection acts on those fishes that are able to survive the decreased oxygen levels. These fishes will breed and increase their numbers. The new generation of fishes will be tolerant to the lower oxygen levels. This new phenotype indicates a change in the genetic composition of the fishes.

In your own words, explain why an earthworm cannot survive if it were cut in half. PLEASE HURRY​
Masja [62]
It cannot survive because an earth worm will not become 2 new worm. The head of the worm may survive and regenerate a tail. But if original tail of the worm may not survive because it will not be able to grow a new head or the rest of its vital organs and it will die. I hope this helps. :)
