Answer:

-What types of toxins were found in the waters of the Lower Passaic Superfund site?

DDT and agent orange were found in the waters of the Lower Passaic Superfund site.

-How were some fish able to survive PCB levels thousands of times higher than sensitive fish can withstand?

in some tolerant fish, the trigger for the changes that can be caused by PCB levels are can be turned off which allows some fish to survive levels of PCB thousands of times higher than the levels affecting sensitive fish.

-What is the advantage of a large population for rapid evolution?

The advantage of rapid evolution is that the animals can survive and not get killed off.

-Do you think all species would be able to evolve adaptations to help them survive pollutants? Why or why not?

I don't think that all fish can get speedy evolutions like the killfish did because researchers think that they got a rare mutation which helped them survive. However as researchers say, in smaller populations with less diversity the chances that a rare mutation might happen is small.

-What will likely happen to these toxin-adapted fish if the waters are eventually cleaned up?

Once the water becomes clean, a tolerant fish with the mutation won't do as well as a sensitive fish would do.

Explanation:

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day! Thank you : )

How do biotic factors rely on abiotic and other biotic factors? PLEASE HELP!!
creativ13 [48]
Biotic Factors depend/rely on abiotic factors because living things (biotic) need nonliving things (abiotic) to survive. Biotic rely on other Biotic factors because they need the food and resources from other living things.

For example, we (biotic factors) need energy from the sun and oxygen/air ,which is abiotic factors, to live and grow. Just like plants (biotic) need the sun's energy (abiotic) to help it grow.
