Which two elements, in looking at their atoms, have a total of 51 protons between them? Question 1 options:

Magnesium and Aluminum

Lithium and Scandium

Tin and Hydrogen

both A and B

its first and third is your answer i did the qustion the fourth isnt right

girl imma just put my comment here because i need a couple point okurrttt

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.
