2019 Biology Entrance Exam – Full Content Guide (Grades 9-12) | Part 2 51-100

🧬 Are you preparing for the 2019 Ethiopian Biology Entrance Exam? This video covers EVERYTHING you need to know – perfect for students in Ethiopia, the USA, Canada, the UK, Europe, China, Australia, and around the world! Whether you're a Grade 12 student in Ethiopia, an international student preparing for university entrance exams (AP Biology, A-Levels, IB), or someone reviewing biology concepts, this video is for you. Our step-by-step explanations make complex biology topics easy to understand! 📚 What You'll Learn: ✅ Chapter 1: Concept of Biology, Biotechnology & Applications Definition of Biology, scientific method, tools of a biologist (microscope) Biology and technology, impacts on society, ethical issues Conservation, food security, sustainable development Applications in biotechnology ✅ Chapter 2: Biochemical Molecules Inorganic molecules (water, mineral salts) Organic molecules (carbohydrates, lipids, proteins, nucleic acids) Monomers, polymers, hydrolysis, condensation reactions ✅ Chapter 3: Cell Biology Cell theory, cell structure and function Prokaryotic vs eukaryotic cells Animal vs plant cells Passive and active transport Levels of biological organization ✅ Chapter 4: Classification, Plants & Animals Taxonomy, five-kingdom system, Linnaean nomenclature Common Ethiopian animals and plants Plant reproduction (pollination, seeds, germination, photosynthesis) Invertebrates vs vertebrates, animal reproduction, metamorphosis Economic importance of insects, animal behavior, homeostasis ✅ Chapter 5: Human Biology & Health Food and nutrition, balanced diet, deficiency diseases Digestive, respiratory, circulatory, nervous, endocrine, reproductive systems Sense organs (skin, tongue, nose, eye, ear) ✅ Chapter 6: Microorganisms Eubacteria, Archaea, Fungi, Protozoa, Viruses Normal microbiota, disease transmission, uses and control of microorganisms Renowned Ethiopian microbiologists ✅ Chapter 7: Heredity & Genetics DNA and RNA structure and function, DNA replication Protein synthesis, mitosis and meiosis Mendelian inheritance (monohybrid, dihybrid, test crosses) Non-Mendelian inheritance, genetic disorders, gene therapy Pedigree analysis, Ethiopian farmers' indigenous knowledge ✅ Chapter 8: Environment, Climate Change & Ecology Ecological hierarchy, food chains and webs, nutrient cycling Population growth (exponential, logistic), population regulation Natural resources, conservation in Ethiopia Climate change (causes, effects on biodiversity, agriculture, forests) Global warming, ozone depletion, acid rain International conventions (UNFCCC, Kyoto Protocol) ✅ Chapter 9: Enzymes Properties and functions, protein structures Enzyme-substrate models (lock-and-key, induced fit) Factors affecting enzyme action (temperature, pH, concentration) Enzyme kinetics, industrial applications Malting in Ethiopian tradition ✅ Chapter 10: Energy Transformation Cellular metabolism (anabolism and catabolism) Photosynthesis (light-dependent and light-independent reactions) Cellular respiration (glycolysis, Krebs cycle, oxidative phosphorylation) ✅ Chapter 11: Evolution Theories of evolution (Lamarck, Darwin) Evidence for evolution, natural selection (types and examples) Human evolution, mutation, genetic drift, gene flow Causes of species extinction Renowned Ethiopian anthropologists and evolutionists 📌 Who is this for? 🇪🇹 Ethiopian Grade 12 students preparing for the ESSLCE / EUEE 🇺🇸 🇨🇦 Students in the USA and Canada preparing for SAT, AP Biology, or university entrance 🇬🇧 🇪🇺 Students in the UK and Europe preparing for A-Levels, IB Biology, or university exams 🇨🇳 Students in China and Asia preparing for international biology exams 🇦🇺 Students in Australia and New Zealannivers Anyone worldwide reviewing Biology concepts! 🔔 Don't forget to LIKE, SHARE, and SUBSCRIBE for more entrance exam content! 💬 Comment below – which topic is the hardest for you?
