UKPSC Biology (Unit 2): Biomolecules, Vitamins, Human Nutrition & Plant Minerals Part of the UKPSC General Science & Technology Revision Series. 1.High-Yield Micro-Notes Vitamins (Nomenclature, Classification & Deficiencies): Vitamins are micro-nutrients that yield zero calories and are assimilated directly without hydrolytic enzymatic digestion. They are grouped by solubility: Water-soluble (Vitamins B-complex and C) and Fat-soluble

UKPSC Biology (Unit 1): Branches of Biology, Cytology, Chromosomes & Cell Division (Solved PYQs & Notes) Part of the UKPSC General Science & Technology Revision Series. 1.High-Yield Micro-Notes Biological Disciplines & Zoological Branches: The scientific study of insects is designated as Entomology (sub-branch of Arthropodology). In comparison, Ichthyology is the biological study of fishes, Malacology

UKPSC Chemistry (Unit 4): Applied Chemistry, Polymers, Cement & Environmental Science Part of the UKPSC General Science & Technology Revision Series. 1.High-Yield Micro-Notes Environmental Chemistry & Atmospheric Acidity: Normal clean precipitation exhibits an inherent slight acidity (pH ≈ 5.6) due to the dissolution of atmospheric carbon dioxide forming weak carbonic acid (CO₂ + H₂O →

UKPSC Chemistry Unit 1: Physical Chemistry, States of Matter, pH Scale & Water Properties 1.High-Yield Micro-Notes Aqueous Equilibria & Neutrality: The pH scale, formulated in 1909 by S.P.L. Sørensen, defines hydrogen ion concentration as pH = -log₁₀[H⁺]. Pure neutral water at 25 °C dissociates equally into H⁺ and OH⁻ ions (each 10⁻⁷ mol/L), yielding an

UKPSC Physics Unit 9: Gravitation, Fluid Properties, Escape Velocity & Astronomy 1. High-Yield Micro-Notes Universal Law of Gravitation: Formulated by Sir Isaac Newton in 1687 (published in Philosophiae Naturalis Principia Mathematica), the law states that every particle attracts every other particle with a mutual force directly proportional to the product of their masses and inversely
