Silver has a density of 10.5g/cm to the 3rd and gold has density of 9.3g/cm to the 3rd. which would have a greater mass, 5cm to the third of silver or 5cm to the 3rd of gold?

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

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? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
