Which species in the food web would be subject to the greatest biomagnification of pesticides applied to the grasses

Biology
1 answer:
zaharov [31]3 years ago
4 0

Answer:

<u><em>Hawk </em></u>

Explanation:

Biomagnification can be described as the accumulation of substances like toxins, pesticides etc in tolerant organisms. The biomagnification tends to increase as the trophic levels of a food chain increase. This is because these substances get more and more accumulated as they move up a food chain.

In the example of the food chain mentioned in this question, the highest trophic level is of hawks, so they will be subjected to the greatest biomagnification.

Would you expect that anions would be physically closer to the oxygen or to the hydrogens of water molecules that surround it in
marshall27 [118]
Anions are negatively charged particles. The water molecule is a polar molecule, that means that, it is partly positive and partly negative. The oxygen atoms in the water molecules are more electronegative more than the hydrogen atoms and they draw the shared electron nearer to themselves than the hydrogen atoms; this make them to be slightly negatively charged while the hydrogen atom is slightly positively charged.
Therefore in solution, the anions would be attracted toward the hydrogen atom that is slightly positive while the cations will be attracted to oxygen atom that is slightly negative.

el electrophoresis is normally set up with the negative electrode at the top of the gel and the positive electrode at the bottom
Marina CMI [18]

Answer:

The DNA will still move towards the positive electrode

Explanation:

Gel electrophoresis is a technique which is used by the molecular biologist to separate the fragments of DNA. In the procedure, a DNA sample of a particular concentration of DNA sample composed of a particular length of DNA is loaded into the samples.

The gel is usually set up with the positive electrode at the bottom and negative at the top which by mistake when placed at the bottom and positive at the top.

The DNA will still move from the DNA wells towards the positive side as the DNA moves in the gel as the DNA posses negative charge due to phosphate groups they have and therefore move towards the positive electrode (opposite charge always).

Thus, the DNA will still move towards the positive electrode is correct.
