Biology study guides

A deep-dive guide to Reporting Category 1 of the Texas STAAR Biology EOC: cell theory and viruses, prokaryotic versus eukaryotic cells, the major organelles, the cell membrane and transport, levels of organization, and cellular homeostasis, with the item types STAAR uses for each.

A deep-dive guide to Reporting Category 2 of the Texas STAAR Biology EOC: DNA structure and replication, protein synthesis, gene mutations, meiosis and chromosomes, Mendelian genetics with Punnett squares, and DNA technology, with the cluster patterns and item types STAAR uses for each.

A deep-dive guide to Reporting Category 3 of the Texas STAAR Biology EOC: the evidence for evolution, natural selection and adaptation, mechanisms of genetic change and speciation, taxonomic classification, and interpreting cladograms, with the item types STAAR uses for each.

A deep-dive guide to Reporting Category 4 of the Texas STAAR Biology EOC: photosynthesis, cellular respiration, how the two compare, enzymes and biological molecules, the interacting human body systems, and feedback mechanisms that maintain homeostasis, with the item types STAAR uses for each.

A deep-dive guide to Reporting Category 5 of the Texas STAAR Biology EOC: the levels of ecological organization, energy flow and food webs, the cycling of matter, population dynamics and carrying capacity, and ecological succession and human impact, with the item types STAAR uses for each.

A deep-dive guide to the scientific investigation and reasoning skills embedded across the Texas STAAR Biology EOC: experimental design and variables, analyzing and interpreting data, writing the short constructed response, and the redesigned STAAR question types, with how each is tested and scored.
