In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This interactive module allows students to examine evidence from brain anatomy, tissue histology, and genetic studies to identify possible targets for the treatment of Alzheimer’s disease.

A number of questions are embedded within the short film The Origin of Species: The Beak of the Finch, which explores four decades of research on the evolution of the Galápagos finches.

This tutorial describes the structure and function of the cancer-causing protein BCR-ABL. It also shows how drugs targeting this protein can help treat chronic myeloid leukemia (CML), a cancer of the white blood cells.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

This model shows the structure of the protein BCR-ABL, which causes a type of cancer called chronic myeloid leukemia.

This model shows a mutated form of the cancer-causing protein BCR-ABL that is resistant to the drug Gleevec.

This model shows the structure of ATP, a molecule that provides energy for cellular processes, including protein phosphorylation.

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

This interactive module explores the different gaits employed by animals and how the nervous system is able to switch between gaits.

This tutorial describes how neurons generate action potentials, and how scientists measure neuronal activity and record the firing of individual neurons.
