AEPA Biology (NT305) study plan

AEPA Biology (NT305) · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Cell Biology and Biochemistry

  • Diagram the four major macromolecule classes and label their monomers, bonds, and two biological functions each

  • Trace the flow of matter and energy through glycolysis, the Krebs cycle, and oxidative phosphorylation, writing net ATP and electron-carrier yields at each stage

  • Compare prokaryotic and eukaryotic cell structures in a side-by-side table, including at least eight organelles or structures

  • Explain how membrane structure determines transport type, giving one example each of simple diffusion, facilitated diffusion, active transport, and osmosis

Your checkpoint

A hand-drawn or digital concept map of cellular respiration and a macromolecule/organelle comparison table, photographed or exported as one file

Week 2

Cell Biology and Biochemistry

  • Describe the stages of the cell cycle and identify the checkpoint at which each stage is regulated

  • Contrast mitosis and meiosis on chromosome number, crossing over, and daughter-cell outcomes

  • Predict the effect of a disrupted enzyme on a metabolic pathway and justify the prediction with enzyme kinetics reasoning

  • Explain how photosynthesis converts light energy into chemical energy, naming the inputs and outputs of the light reactions and the Calvin cycle

Your checkpoint

A 15-question self-quiz you write yourself on cell biology and biochemistry, with an answer key and a scored attempt

Week 3

Genetics and Evolution

  • Solve monohybrid and dihybrid crosses and state the expected phenotypic ratios without looking them up

  • Distinguish among incomplete dominance, codominance, multiple alleles, and sex-linked inheritance using worked examples

  • Trace the central dogma and predict the protein change caused by a substitution, insertion, or deletion mutation

  • Interpret a pedigree to determine the most likely mode of inheritance and defend the choice

Your checkpoint

A worked problem set of 10 genetics problems (crosses, pedigrees, mutations) with full solutions shown

Week 4

Genetics and Evolution

  • Summarize the evidence for evolution from fossils, comparative anatomy, molecular data, and observed change

  • Explain natural selection as a mechanism, listing the conditions required for it to operate

  • Define and give examples of the Hardy-Weinberg conditions and calculate allele frequencies from genotype data

  • Distinguish among directional, stabilizing, and disruptive selection and among allopatric and sympatric speciation

Your checkpoint

A one-page synthesis sheet of evolutionary mechanisms plus three solved Hardy-Weinberg calculations

Week 5

Organismal Biology: Structure, Function, and Diversity

  • Compare the major animal phyla on body symmetry, germ layers, and body cavity type

  • Relate the structure of plant tissues and organs to their transport and support functions

  • Explain how the major human organ systems maintain homeostasis, giving one feedback loop example each for endocrine and nervous control

  • Match each vertebrate class to its key adaptations for gas exchange, reproduction, and thermoregulation

Your checkpoint

A comparative diversity chart covering at least eight phyla or groups with the required comparison columns filled in

Week 6

Organismal Biology: Structure, Function, and Diversity & Ecology and the Environment

  • Describe how the structure of a mammalian organ system supports its function, tracing one molecule from intake to use and excretion

  • Define the levels of ecological organization and give a concrete example at each level

  • Explain energy flow through trophic levels and calculate the effect of a 10% transfer efficiency on a food chain

  • Contrast the major biogeochemical cycles in terms of reservoirs and key processes

Your checkpoint

A labeled diagram of one organ system with an annotated molecule pathway, plus a solved trophic-efficiency calculation

Week 7

Ecology and the Environment

  • Compare population growth models and identify the factors that regulate population size

  • Classify species interactions as mutualism, commensalism, parasitism, predation, or competition, predicting the effect on each population

  • Explain succession, biodiversity, and the factors that influence ecosystem stability

  • Evaluate a human impact scenario and propose evidence-based mitigation, distinguishing correlation from causation

Your checkpoint

A written response to one human-impact scenario (roughly 500 words) that includes a claim, evidence, and a mitigation plan

Week 8

Scientific Inquiry and the Nature of Science & Cell Biology and Biochemistry & Genetics and Evolution & Organismal Biology: Structure, Function, and Diversity & Ecology and the Environment

  • Design a controlled experiment on a biology question, identifying independent, dependent, and controlled variables and a valid control group

  • Critique sample experimental designs for bias, confounding variables, and inappropriate conclusions

  • Interpret data presented in tables and graphs and distinguish observation from inference

  • Complete a full-length timed practice test and categorize every missed item by domain

  • Re-teach the two weakest domains using your own notes and re-test those items

Your checkpoint

A scored full-length practice test with a written error log that tags each miss by domain and lists one corrective action per miss

Milestones

Week 2: Score at least 80% on your self-written cell biology and biochemistry quiz, and explain the respiration concept map aloud from memory in under five minutes

Week 4: Solve all 10 genetics problems and all three Hardy-Weinberg calculations correctly without notes, and state the conditions for natural selection from memory

Week 6: Complete the diversity chart and organ-system diagram, and correctly predict the population effect of at least four species interactions

Week 8: Score at least 75% on the full-length practice test with no single domain below 60%, and have a completed error log with a corrective action for every missed item
