Explanation:
Once we were one big continent, so similarities on coasts of two different continents is evidence of them being once together
<span>The first desirable trait that is being engineered into our crops is sustainability. This means that crops are being bred to be able to grow in adverse conditions, ensuring the ability to sustain our food supply as humans. The second, are the alterations being genetically done to crops to eliminate the need for pesticides. By heightening the crops natural ability to eliminate and deter pests, there are higher yields and the elimination of pesticides seeping into and poisoning the human consumer. And, finally an ability to eliminate the need for traditional breeding in crops. By genetically replicating plants, we are eliminating the chance that the human race may "run out", of seeds, of starts, of the need for pollination. This basically ensures us an unlimited food supply, just in these three traits being bred into our crops.</span>

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.

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day! Thank you : )
When u need a question answered you click on the camera or you could even type it but I like the camera and u just take a picture of the problem and then u go to the most recent ones that have the correct question on it and scroll down and see the answers but for me I check if there are more than 2 answers of the same one before answering it.
