This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.
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 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 the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.
