Moseley made revisions to the periodic table that resolved some of the problems with Mendeleev's version, which accounted for variations from isotopes

Explanation:

yes he did, he restated the period law because mendeleev arrange the elements in order of their atomic mass. Mosley says that since elements of same atom have different atomic masses but no elements of same atom have different atomic number

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "
