Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Identify and describe the properties of life
Describe the levels of organization among living things
Recognize and interpret a phylogenetic tree
List examples of different subdisciplines in biology

Paul Andersen explains how biogeochemical cycling is used to move nutrients from the environment into living material and back again. He explains the water cycle, the carbon cycle, the nitrogen cycle and the phosphorus cycle. He also explains the CHNOPS mnemonic device. He also explains why organisms need carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. [10:07]

Science Buddies offers a career description of a biochemist. If you have an interest in both biology and chemistry, this might be a good fit for you. Read the "On the Job" section to find out all the different things a biochemist does. This site lays out the requirements needed to become a biochemist, as well as the education and job description. Included are interviews with people who have pursued this career.

Here you can find all kinds of helpful information about chemistry. Learn about reactions, elements, atoms, matter, or biochemistry. Downloads and activities are also included.

Here you can learn about biochemistry, the chemistry of the living world. Content explores carbohydrates, lipids, amino acid structure and proteins, enzymes, nucleic acids, and metabolism.

The ACS Education Division is making educational resources available by topic to aid parents and teachers in student enrichment during this time of distance learning. We have bundled materials from the Reactions Video series, C&EN, our magazines within the Education Division and our portfolio of hands-on activities for students in grades K–12 and beyond. These resources focus on five topics — The Earth, Water, Food, Health & Your Body, and The Periodic Table — and put a spotlight on the connection between chemistry and everyday life.

This digital textbook covers core chemistry concepts and includes interactive features, real-world examples, and videos.

Student teams learn about engineering design of green fluorescent proteins (GFPs) and their use in medical research, including stem cell research. They simulate the use of GFPs by adding fluorescent dye to water and letting a flower or plant to transport the dye throughout its structure. Students apply their knowledge of GFPs to engineering applications in the medical, environmental and space exploration fields. Due to the fluorescing nature of the dye, plant life of any color, light or dark, can be used unlike dyes that can only be seen in visible light.
