Description: A detailed overview of meiosis and its contributions to genetic diversity and an intro into heredity.

AP Biology

Learn about the chemistry of life in unit 1 of the AP Biology course. We'll cover topics such as the structure of water, hydrogen bonding, elements of life, biological macromolecules, and nucleic acids. Prepare for the exam with these resources and you be on your way to crush the AP Bio exam!

Unit 1 – Chemistry of Life

Unit 2 of AP Biology covers cell structure and function. We'll go over key topics such as subcellular components, cell size, plasma membranes, membrane permeability, membrane transport, facilitated diffusion, tonicity, osmoregulation, and cell compartmentalization. 

Unit 2 – Cell Structure & Function

Unit 3 of AP Biology is all about cellular energetics. Review topics such as enzyme structure, enzyme catalysis, environmental impacts on enzyme function, cellular energy, and photosynthesis. 

Unit 3 – Cellular Energetics

Learn about how cells communicate and reproduce in unit 4 of AP Biology. Our study guides for unit 4 cover cell communication, signal transduction, changes in signal transduction pathways, feedback, cell cycle basics, and regulation of the cell cycle. 

Unit 4 – Cell Communication & Cell Cycle

Get a solid understanding of heredity in unit 5 of the AP Biology exam. We'll cover topics such as meiosis, genetic diversity, mendelian genetics, non-mendelian genetics, environmental effects on phenotype, and chromosomal inheritance. 

Unit 5 – Heredity

Join us in exploring gene expression and regulation for the AP Biology exam. We'll cover all the topics in unit 6, such as DNA and RNA structure, replication, transcription, RNA processing, translation, regulation of gene representation, cell specialization, mutations, and biotechnology. 

Unit 6 – Gene Expression & Regulation

Understanding natural selection is crucial to learning about how ecosystems function. Learn about unit 7 of AP Biology as we cover topics such as artificial selection, population genetics, hardy-weinberg equilibrium, evidence of evolution, common ancestry, continuing evolution, phylogeny, speciation, extinction, and origin of life on earth. 

Unit 7 – Natural Selection

Ecology is all about the interactions that organisms have amongst themselves and with their environment. In unit 8 of AP Biology, we'll cover topics such as responses to the environment, energy flow, population ecology, the effect of density of populations, community ecology, etc. 

Unit 8 – Ecology
