What advantage does a heterogeneous catalyst provide over a homogeneous catalyst in industrial processes? a. a heterogeneous catalyst provides a higher reaction rate. b. a heterogeneous catalyst can be easily separated from reactants. c. a heterogeneous catalyst raises the activation energy higher. d. a heterogeneous catalyst provides an alternate reaction pathway.

B, a heterogeneous catalyst can be easily separated from reactants

Explanation:

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.
