Study Notes
Biology: DNA and Genetics
- The structure of DNA: phosphate, ribose sugar, nitrogen base (A, C, G, T) in a double helix shape with complementary base pairing.
- DNA components: genes, chromosomes, autosomes, sex chromosomes (XY, XX).
- Chromosome structure: gene distribution and genetic information storage.
- Proteins: polypeptides, amino acids, and genetic coding.
- Gametes: haploid, diploid, and their roles in reproduction.
- Genotypes and phenotypes: homozygous, heterozygous, dominant, recessive, X-linked, and Y-linked traits.
- Punnett squares: predicting offspring genotypes and phenotypes.
- Pedigree analysis: tracing genetic traits in families.
- Gene technology: applications and advancements.
Chemistry
- Atomic structure: protons, neutrons, electrons, and mass number.
- Electronic configuration and periodic table organization.
- Chemical equations: writing and balancing reactants and products.
- Law of conservation of mass: matter cannot be created or destroyed.
- Symbols, formulas, and ions: anions, cations, and ionic bonding.
- Covalent bonding: molecular structure and properties.
- Reaction types: precipitation, combination, decomposition, and neutralization.
- Ion tables and ionic bonding: electrostatic attraction.
The Scientific Method
- Practical reporting: aim, hypothesis, observations, data tables, and graphing.
- Variables: independent, dependent, control, and controlled.
- Conclusion drawing: data analysis and error consideration.
- Errors, accuracy, precision, outliers, and bias: understanding data limitations.
Natural Selection & Evolution
- Natural selection: adaptation, variation, and species survival.
- Artificial selection: selective breeding and its applications.
- Steps leading to natural selection: peppered moth, insects, and bacteria examples.
- Species definition: biological differences and reproductive isolation.
- Speciation: variation, isolation, and selection leading to new species.
- Evidence for evolution: comparative anatomy, DNA structure, embryology, and origins.
