29) Imagine you’re a biology instructor lecturing to a group of students interested in ecology, the branch of biology that studies interactions between organisms and their environments. The students complain bitterly that they’re not interested in atoms and molecules because these are irrelevant to their interests. As a responsible instructor aiming to provide a complete and meaningful education, you would state:
A) “You need to study atoms and molecules because the organization of life is hierarchical; this implies that, to understand the complex (ecology), you first need to understand the simpler underlying levels.”
B) “You need to study atoms and molecules because life exists at the level of the atom.”
C) “You need to study atoms and molecules because they’re important for many things.”
D) “You need to study atoms and molecules because all biologists, regardless of their specific interests, should know about them.”
E) “You need to study atoms and molecules because it’s in the book.”

A) only the origin of life.
B) only the unity of life.
C) only the diversity of life.
