Marlene is writing a research paper on how bees play
different roles in a hive. She interviews her neighbor who
studies bees. Her neighbor tells her that honeybees'
brain chemistry changes as the bees assume new roles.
Marlene wants to explore that topic further and decides
to add a research question to her research plan.
Which research question should Marlene add?
O What are all the roles of honeybees in a hive?
O How are honeybees different from other bees?
O What did scientists find out about the brain chemistry
of honeybees?
O How does the brain chemistry of honeybees change
during their lives?
