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

College-level online biology course highlighting the fundamental principles of biochemistry, genetics, molecular biology, and cell biology. Course features include video lectures, audio lectures, subtitles/transcripts, lecture notes, assignments and solutions, and exams and solutions.

College-level introductory biology course focusing on the application of the fundamental principles of human biology. Course topics include genetics, cell biology, molecular biology, disease (infectious agents, inherited diseases and cancer), developmental biology, neurobiology, and evolution. Course features include video lectures, audio lectures, subtitles/transcripts, lecture notes, assignments and solutions, and exams and solutions.

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]

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.

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.

Learn all about organic chemistry, biochemistry, and synthetic polymers in this detailed online chemistry book. Contains chapter objectives, a glossary, and a great deal of review and practice material.

This detailed presentation gives an extensive overview of organic chemistry, biochemistry, and synthetic polymers. Provides a great review of the chemical structure of many common compounds.

Use this site to get an overview of organic chemistry, biochemistry, and synthetic polymers. Also includes an answer key to the chapter review questions and links to online quizzes.

This NetLogo model of leaf photosynthesis shows the macroscopic outcome of the reaction.

This simulation provides the opportunity to practice performing a ligation
reaction in a virtual lab setting. This process uses the enzyme DNA ligase
to attach two DNA fragments using complementary blunt or sticky ends
generated from a restriction enzyme digest.

This pathway provides an overview of biological macromolecules and their properties. The resources in this pathway can be used to introduce or review the structure and function of lipids, carbohydrates, proteins, and nucleic acids. For a deeper look at this topic, we recommend the pathway Biological Macromolecules from the OpenStax textbook Biology for AP® Courses.

Matt Meselson takes us on a journey through his long and storied career, including 60 years as a Harvard biology professor. From memories of his earliest science experiments as a small child to his non-traditional learning path, which included service learning during WWII, to musings on the spirit of cooperation in managing a pandemic and the future of biology and humanity, this episode gives us an insight into a legendary figure in biology. A new virtual interview series from LabXchange at Harvard University, the Xchange showcases the diverse roles, projects, and initiatives that make up the intersecting fields of science, education, and health. Hosted by LabXchange Faculty Director Robert Lue, our first season features a range of perspectives on the impact of COVID-19.
