The answer is degree of ionization. I'm guessing you have already taken the quiz.
B
While nuclear energy does not pollute the environment, it poses the risk of radiation which is harmful to organisms because it causes lethal mutations.
Explanation:
Nuclear fission, for example, releases neutrons and other particles (at very high speeds) that can ionize materials including DNA. This will induce mutations of DNA most of which are usually lethal to organisms. Gamma and X- rays are also produced by fusion reactions and if exposed to organisms also cause mutations on DNA through double stranded breaks. Therefore, the risk of an accident of a nuclear reactor can have immense ramifications on the ecosystems.

Answer:
no. Because there is always that one person who doesn't want to
The question has mentioned three solvents: water, ethanol, and diethyl ether. Water is miscible with ethanol but not diethyl ether. As a result, it would be possible to separate a mixture of water and diethyl ether with a separatory funnel but not a mixture of water and ethanol using such techniques.
Substance X dissolves well in diethyl ether but not in water; substance Y dissolves well in water but not in diethyl ether. As a result, the two components of this mixture would end up in different layers when dissolved in a mixture of water and diethyl ether- which separate into two layers itself. One would expect to find
- a solution mostly of substance X in the diethyl ether layer, and
- a solution mostly of substance Y in the water layer.
Given the fact that diethyl ether has a density less than that of water (
as opposed to 
,) it would form the upper layer of its mixture with water. Separate the mixture with a separatory funnel. The question stated that both X and Y are under the solid state while the two solvents are both liquidsm implying that the boiling points of both species are higher than that of their respective solvent. Therefore heat the solutions till all solvent had evaporated to obtain X and Y.
