Effect of Chemical spillage on ecology"the living wil die " I'd not dramatize the effect. We dont know the toxicity of this "pesticide" or it's solubility - both of which will be important to understanding acute and chronic affect. We do know it's "lipophilic" so can expect bioconcentration. ...

Effect of Chemical spillage on ecology... for the "most affected". The information offers the focus of contamination, the initial vector for spread (water flow) and that the pesticide is lipophilic - has an affinitiy for lipid/fat thereby probably persistent and accumulative. Lipophilic in this context does not necessarily ...

Effect of Chemical spillage on ecology... fish species in the area, one that lives in the river, and one that lives in the fish ponds. You know that Chemical X is a chlorinated, lipophilic pesticide. You also know that the waterbirds in the area consume primarily fish. (a) What do you think will be the most likely distribution of Chemical ...

Re:... not convince you about beneficial mutations in multicellular organisms, there are plenty of more to find. Just try googling something like insect pesticide resistance, for example. Unfortunately, it seems you have already carved your own views into stone and no matter what evidence and examples ...
