• respond to their environment.

• be less complex.

The process by which organisms keep everything inside their bodies within certain limits is called

• Homeostasis

• evolution

• metabolism

• photosynthesis

A scientist working in which area of biology is MOST likely to study DNA?

• interdependence in nature

Focusing on which two central themes in biology would help a student understand why animals come in different shapes and sizes?

• cellular basis for life; homeostasis

• structure and function; unity and diversity of life

• matter and energy; homeostasis

• science as a way of knowing; interdependence of nature

Biologists who work in the fields of genomics and molecular biology study

• DNA

• diseases

• trees

A paleontologist would likely be most interested in finding

• weapons for an evolutionary arms race with disease-causing organisms.

• a universal Tree of Life.

• weather patterns that affect life on Earth.

• genetic codes to rewrite.
