Study Notes
Unit 1: Laboratory General Procedures, Safety, Emergency Procedures and Biology Lab Equipment
- Lab Equipment Identification: Use the provided letter codes to identify lab equipment (e.g., Beaker = A, Forceps = C).
- Safety Procedures: Always know the location and use of safety equipment (safety shower, eye wash, fire extinguisher).
- Sharp Instrument Safety: Direct sharp instruments away from yourself and others.
- First Aid for Cuts: If cut in biology lab, apply direct pressure to the cut and seek immediate medical attention (severe or non-severe).
- Reporting Accidents: Report any accident, breakage, or procedure error immediately to the teacher.
- Disposal of Used Matches: Place used matches in a water-filled container, never in a waste container.
Unit 2: The Science and Chemistry of Life
-
Relative Acidity: pH 2 solution is 100 times more acidic than a pH 0 solution.
-

Unit 3: Biochemistry-Essential Compounds
-
Macromolecules: Carbohydrates, lipids, nucleic acids, and proteins.

- Hypertonic: Water flows out of cell (cell shrinks/ shrivels).
- Isotonic: Water flows in and out equally (no change).
-
Transport Types: Active transport requires energy (ATP) to move substances against their concentration gradient; passive transport does not.

Units 8 and 9: Cell Reproduction and Modern Genetics
- Meiosis: Cell division that produces genetically diverse daughter cells (gametes).

- Phases of Mitosis: Prophase, metaphase, anaphase, and telophase.
- Phases of Meiosis: Distinct stages in meiosis, focusing on prophase I, anaphase I and II.
- Genetic diversity: Meiosis produces gametes (haploid cells).
Supplementary Information
- Punnett Square: A tool for predicting possible genotypes of offspring.
