Freshwater ecosystem type is the factor that does not determine the strength of a toxic in an aquatic ecosystem.
- A toxin is a substance which is responsible for causing detrimental effects on the body of the living organisms.
- The excess dose of toxin can produce lethal effects in living beings.
- The strength of the toxin is determined by its amount or concentration in the water body more the amount or concentration of toxin the more will be its strength.
- The strength of toxin can be determined by its absorption in the aquatic organisms like gills of fishes more the absorption more will be the strength and more will be the impact.
- The strength of toxin can also be determined by the mutation it can cause more the number of mutation it can cause more lethal will be the effect.
- The freshwater ecosystem is a source of freshwater which will be free from saline water. It can be a river, lake, pond, or others.
- It does not matter which type of freshwater ecosystem is affected by the toxin. If the toxin is able to mix with the water then it can be absorbed by the aquatic organisms and the toxin will exert its negative effects.
- Hence, freshwater ecosystem type is the correct option.

Answer:
Explanation:
Hello,
In this case, for the given balanced chemical reaction:
Thus, since hydrogen and hydrogen iodide are in a 1:2 mole ratio, we can easily compute the yielded volume as shown below:
Thus, is possible, due to the Avogadro's law which allows to relate moles and volume by a directly proportional relationship.
Regards.
Answer:
Reduction
Explanation:
Gaining electrons means reduction. When the electrons are on the reactant side of the reaction, they are added to the other reactant. This indicates that the Sn^4+ is gaining electrons and is therefore reduced (reduction).
Benzene is the simplest example of the aromatic compound
Firstly, we want to explain what is the meaning of aromaticity?
the aromaticity is called on any compound which has cyclic shape and has a resonance. Resonance is delocalization of the electrons (which form the double bond) in the molecules, in other words, the double bond moves through the compound by the movement of electrons which leads to increasing the stability of the compound by this process which called resonance. The resonance may occur in open or cyclic compounds, and if it occurs in cyclic compounds, these compounds are called aromatic compounds. So, the benzene considered to be the simplest aromatic compound where it is not only has a resonance in a cyclic ring but also it was the first aromatic compound discovered and also, the most common aromatic compounds are derivatives of it (benzene).
