Theme # 2

Biology is arranged

according to levels of

organization.

Novel properties emerge

at each level as a result

of the interactions

among components at

the previous levels.

Theme # 3

Through regulation,

organisms maintain

different internal

environments

from their external

environments.

Theme # 4

Organisms exchange materials and

energy with their surroundings. Theme # 5

All organisms require energy

to perform work. Theme # 6

Theme # 7

Though diverse, life

can be grouped

into three domains

with closely-

related species

sharing many

characteristics.

Darwin’s theory of natural selection: Populations adapt to their environment through the

differing reproductive success of varying individuals. Theme # 8

Form and function are correlated

at all levels of the biological

organization. Theme # 9

The process of science

includes discovery, testing

of hypothesis, and

repeatability of

observations and

experiments.

Theme # 10

Technology is goal-oriented application of science. Theme # 11
