Study Notes
- Biology is the scientific study of life and living organisms.
- It encompasses various sub-disciplines such as botany (study of plants), zoology (study of animals), microbiology (study of microorganisms), genetics (study of genes and heredity), and ecology (study of ecosystems).
- Cells are the basic unit of life, and organisms can be unicellular (composed of a single cell) or multicellular (composed of multiple cells).
- DNA (deoxyribonucleic acid) carries genetic information and is responsible for inheritance.
- Evolution is the process by which species change over time through natural selection, genetic drift, and other mechanisms.
- Energy flow occurs in ecosystems through the food chain, starting with producers (plants) and moving to consumers (animals) and decomposers.
- Homeostasis is the ability of an organism to maintain internal stability despite external changes.
- Classification categorizes organisms into a hierarchical system based on evolutionary relationships, with domains being the broadest category followed by kingdoms, phyla, classes, orders, families, genera, and species.
- The scientific method is used in biology to make observations, ask questions, form hypotheses, conduct experiments, analyze data, and draw conclusions.
- Biotechnology applies biological knowledge to develop technologies and products to improve human life, such as genetically modified organisms (GMOs) and medical advancements.
