A. 1. What properties are shared by all living organisms? 2. Understand the hierarchical relationships of life – i.e., how are atoms related to molecules? How are populations related to communities? 3. Know the steps of the scientific method, and be able to recognize a reasonable hypothesis, and a logical experiment for testing the hypothesis, for a given scenario. 4. Be able to interpret a graph representing data that are provided for you. 5. Understand the relationships between a chromosome, a gene, and DNA. 6.
