Grade 12 text book all sumerised with competencies

Key Content Breakdown The document is organized into six primary units, summarizing fundamental biological concepts: Unit 1: Application of Biology: Explains the practical role of biology in conserving natural resources and ensuring food security. It also covers advancements in biotechnology, genetic engineering, and agriculture. Unit 2: Microorganisms: Outlines the three domains of life (Archaea, Bacteria, Eukarya). It details the structural characteristics, reproduction, and health impacts of various microbes, including fungi, protozoa, and viruses. Unit 3: Energy Transformation: Breaks down cellular metabolism into catabolic and anabolic processes. It provides step-by-step summaries of photosynthesis (light-dependent and Calvin cycle) and the four stages of aerobic cellular respiration. Unit 4: Evolution: Discusses the historical theories on the origin of life and Darwin's theory of natural selection. It reviews the mechanisms of evolution, such as mutation and genetic drift, alongside a brief overview of human evolution. Unit 5: Human Body System: Describes body coordination via the nervous and endocrine systems. It details the anatomy and function of key sense organs (skin, eye, ear) and the mechanics of homeostasis (thermoregulation and osmoregulation). Unit 6: Climate Change: Defines the causes of climate change, emphasizing the enhanced greenhouse effect. It reviews the global impacts on biodiversity and human health, international climate conventions, and Ethiopia's specific Climate Resilient Green Economy strategy.
