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

This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

This interactive module explores niche partitioning, a mechanism that enables similar species of animals to coexist.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

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 interactive module explores key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity.

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.
