5. Jack and Jill Smith are planning to have a baby together. Jack has brown eyes, and he carries one dominant allele for brown eyes and one recessive allele for
blue eyes. Jill has blue eyes, and she carries two recessive alleles for blue eyes.

What percent chance is there that the baby will have brown eyes?

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.
