01
Cells & Energy
free / beginner
Membrane Transport
Move particles across a membrane and see gradients do the work.
all access / intermediate
Cellular Respiration
Follow energy as molecules are rearranged inside a cell.
free / intermediate
Cell Cycle & Mitosis
Follow a cell through growth, DNA duplication, checkpoints, and division.
02
Genetics & Information
free / beginner
DNA Replication
Unzip a strand and follow the rules that copy its information.
all access / intermediate
Mendelian Inheritance
Combine alleles and see probability take shape across offspring.
all access / intermediate
Protein Synthesis
Translate a gene from DNA into an RNA message and an amino-acid chain.
free / advanced
Gene Regulation
See how cells decide which instructions to read and when.
03
Human Systems
free / intermediate
Action Potential
Push a membrane past threshold and follow the signal through time.
all access / intermediate
Cardiac Cycle
Track pressure and valves as one heartbeat moves blood forward.
all access / intermediate
Immune Response
Layer innate defense, adaptive recognition, antibodies, and memory against a threat.
free / beginner
Homeostasis
Disturb a regulated variable and see feedback bring it toward a set point.
all access / advanced
Neuroscience
Follow signals from individual neurons into perception and behavior.
free / advanced
Immunology
Track recognition, response, and memory as the body meets a threat.
04
Evolution & Ecology
free / intermediate
Evolution & Natural Selection
Change variation, selection pressure, and generations to watch a population shift.
all access / intermediate
Ecosystems & Energy Flow
Trace energy through trophic levels while nutrients cycle back through decomposers.
free / advanced
Population Genetics
Track how variation and selection reshape a population over generations.
