Introduction to Science

Scientific progress is made by asking meaningful questions and conducting careful investigations. (7.7)

Cell Biology

All living things are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope. (7.1)

Genetics

A typical cell of any organism contains genetic instructions that specify its traits. Those traits may be modified by environmental influences. (7.2)

Evolution

Biological evolution accounts for the diversity of species developed through gradual processes over many generations. (7.3)

Earth and Life History

Evidence from rocks allows us to understand the evolution of life on earth. (7.4)

Structure and Function in Living Systems

The anatomy and physiology of plants and animals illustrates the complimentary nature of structure and function. (7.5)

Physical Principles in Living Systems

Physical principles underlie biological structures and functions.  (7.6)
