3. How is fission different from radioactive decay? a. fission is the forcible splitting of an atom, decay occurs naturally
b. fission requires release of radiation, decay doesn’t release radiation
c. fission releases neutrons, decay releases beta particles
d. fission is more common than radioactive decay

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

it is the most commonly accepted one

the right answer is c i just did the question.

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.
