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.
