What electronegative atom do we often associate with polarity? for example, its presence can sometimes increase the polarity of a compound, but its placement in the molecule is also important. a. carbon b. hydrogen c. oxygen

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.
