After seeing a graph represented below, I have recognized the correct answer, and I think that the statement concerning the oxygen level in the lake which can be inferred from the graphs is being revealed by the option 1 -<span>Trout and whitefish require higher oxygen levels than do carp. As you can see the oxygen line on the graph shows that carp does not require as much oxygen as whitefish does require, as level is increasing on the left side.
Hope you will find it helpful!

What we can observe in order to visualize Mendel's Law of Segregation is homologous chromosomes separating during meiosis I. The correct answer is E.
Answer:
During the process of gel electrophoresis, the DNA separates on the basis of charge to mass ration and forms bands as it moves towards the positive end of the gel.
If the electricity is kept running for too long, then the DNA will continue to run in the positive direction and might exit the far end of the gel. As a result, there will be no band formation due to which the experiment will become incorrect.
ecosystem is the right answer
