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

This interactive module introduces the anatomy of the immune system and walks through the timeline of a typical immune response.

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

This interactive module allows students to examine fossils of early humans and compare them to modern primates.

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 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.

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.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

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