Open Ended/Essay (16 points see rubric)
Explain how the structures of cells, tissues, organs, and organ systems
in multicellular organisms are interconnected and contribute to the
survival of the organism. Explain how each level of organization
depends on the level below it to support life.
Reference in your response:
-The importance of a single organ to keeping an organ system running
and the negative consequences of organ failure.
-The importance of each organ system in keeping an organism alive and
giving it the ability to accomplish complex tasks such as moving an arm
or flapping a wing.
