In this article, see a learning sequence where students explore symbiotic relationships and cell communication in bacteria (quorum sensing) by connecting their prior knowledge regarding ocean ecosystems to their understanding of symbiotic relationships.
In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.
This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the second of three animations about cellular respiration.
