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

Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.

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.

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

Several questions are embedded within the short film The Making of the Fittest: Natural Selection and Adaptation, which uses the rock pocket mouse as a living example of natural selection.

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 three examples of recent human adaptations: lactose tolerance, sickle cell disease, and bitter taste perception.

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

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