Question

Fish and other aquatic organisms are exposed to many types of water pollutants, including metals such as aluminum. Although a low level of aluminum is found in unpolluted water, many lakes and streams have an increased level because of mining, sewage treatment, and accidental spills of toxic materials. Aluminum pollution can result in mass fish die-offs.

Why did the scientists do this experiment in a laboratory instead of simply collecting fish from a river with a high aluminum level and documenting their osmoregulatory ability?

Accepted Answer

Hey everyone, let's take a look at this question together, Which of the following heavy metal pollutants cause severe toxicity and fish. Now let's talk about what we know about those heavy metal pollutants. So we've learned before that heavy metal has to do with those metals or even the metal Lloyd's that have high density. And so some examples of those include lead or arsenic or mercury or some other things like silver, aluminum cadmium, there's so there's various heavy metals and so what they do is they affect certain metabolic pathways of those fish and they can cause massive fish die offs. So the correct answer here is answer choice D all of the above. Because all those answer choice lists their arsenic aluminum cadmium are all heavy metal pollutants that affect those metabolic pathways of fish like interfering with the sodium potassium 80 P. A. S. Or osmolarity because they can cause stress which weakens the immune immune system and they basically affect several different life functions of the fish. So all options, there are heavy metal pollutants that cause severe toxicity and fish. I hope you found this video to be helpful. Thank you and goodbye.
