Study Notes
- Biology is the scientific study of life, encompassing a broad scope with unifying themes such as cellular structure and function, heredity through genes, and evolution.
- Life is composed of organisms, which are made up of cells that contain hereditary information encoded in genes, enabling continuity through generations.
- Evolution is another key theme, explaining the unity and diversity of life through natural selection acting on genetic variation.
- Energy processing is crucial for life, allowing organisms to move, grow, and reproduce.
- Biologists investigate life at various levels, from molecular biology to anatomy and physiology, and population evolution, utilizing the scientific method.
- Life on Earth, which emerged over 3.7 billion years ago, exhibits immense diversity, from prokaryotic organisms like archaea and bacteria to eukaryotic organisms including protists, fungi, plants, and animals.
