One slice of bread provides you with 50 nutritional calories of energy. if a 1-1b loaf of bread contains 18

and 1 cal = 4.18 j)

so what is the problem with your lab report and whats the subject of the lab report? i will you

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.
