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

This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.

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

The added information provided at pause points within the animation How We Get Our Skin Color allows for a richer exploration of the topic of human skin structure and function.

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

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 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 tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.

This tutorial describes the various forms of “fat” — from a tissue, to a cell type, to a class of molecules.

This tutorial explores how fat is digested, transported, stored, and used for energy.
