Topics covered on this exam include: Populations, communities, ecosystems, mitosis
and meiosis. Labs to be considered: owl pellet (TR group), Red Queen, Microscope lab,
and the egg lab).
Below are some questions/suggestions that you should be familiar with for the exam.
Don’t forget to bring a scantron and a number two pencil to the exam.
Please email me with questions, should they arise.
