Test Corrections

If you made 79 or lower you have the opportunity to learn the concepts on the test.

On a sheet of notebook paper write the questions that you missed.

Give the correct answer and explain where you found the answer. Ex. Organism chart or page in textbook

Organization of Multicellular Organisms

Learning goal (7.L.1.3): Multicellular organisms are organized into many different parts that build on each other and must work together to meet the needs of the organism.
