HOMEWORK  1. Levels of Organization List the levels of organization from atoms to biosphere. Obtain a actual job description for each (from Science or the Chronicle. of Higher Education).

HOMEWORK  1. Levels of Organization List the levels of organization from atoms to biosphere. Obtain a title of a research article for each or a job description for each.  2. Characteristics of Life Most biologist do not consider viruses to be alive. Which characteristics of life to they have and which do they lack? Give a brief (1-2 sentences) reason why or why not for each characteristic.
