Cheat Sheet
- Cellular Structure & Function -
Review the roles of major organelles like mitochondria for ATP production, the nucleus for genetic storage, and ribosomes for protein synthesis, as detailed in Alberts' Molecular Biology of the Cell (NCBI). Understand the fluid mosaic model of membranes (lipid bilayer with embedded proteins) to ace related biology trivia. Mnemonic tip: "Many Neat Raccoons Eat" helps recall Mitochondria, Nucleus, Ribosomes, ER.
- Genetic Inheritance & Punnett Squares -
Practice Mendel's laws of segregation and independent assortment by constructing Punnett squares to predict monohybrid and dihybrid cross ratios. For example, crossing two heterozygous pea plants (Aa × Aa) yields a 3:1 dominant-to-recessive phenotype ratio in offspring. Remember the phrase "Gametes Align, Genes Design" to recall how alleles segregate and randomly assort.
- Evolution & Hardy-Weinberg Equilibrium -
Familiarize yourself with the Hardy-Weinberg equation (p² + 2pq + q² = 1) to calculate allele frequencies in non-evolving populations, as outlined in Nature Reviews Genetics. Apply simple problems like predicting q if p = 0.7, then q = 0.3 and genotype frequencies follow suit. Mnemonic "P = Prevails, Q = Quota" helps keep track of major and minor allele frequencies.
- Bioenergetics & Metabolic Pathways -
Trace key steps in glycolysis and the citric acid cycle to see how each glucose molecule yields about 30 - 32 ATP, as described by biochemistry texts on PubMed. Learn the "Goodness Gracious, Father Franklin Did Go By Picking Pumpkins" rhyme to remember glycolysis intermediates from Glucose to Pyruvate. This groundwork is essential for tackling tougher questions on energy metabolism in your biology IQ test.
- Ecology & Trophic Dynamics -
Understand energy flow through ecosystems using the 10% rule and food chain hierarchies, drawing on case studies like Yellowstone wolves (Science journal). Explore how keystone species and trophic cascades shape biodiversity and ecosystem stability. Mastering these concepts will boost your confidence for any iq biology challenge or biology quiz scenario.
