Study Notes
Biology: The Study of Life
- Biology is the study of life, leading to unforeseen discoveries, e.g., Pacific yew tree and cancer treatment, Crystal Jellyfish and GFP discovery, Arrowhead Viper and inhibitors of high blood pressure, Streptomyces griseus soil bacteria and streptomycin, and White willow tree and aspirin.
Characteristics of Life
- Cells and organization: the simplest unit of an organism is the cell, and all living things can be called organisms.
- Energy use and metabolism: energy is the capacity to do work, and cells use energy by catalyzing chemical reactions.
- Response to environmental changes: living things respond to internal and external changes.
- Regulation and homeostasis: living things maintain internal order and regulate their internal environment.
- Growth and development: living things grow and develop.
- Reproduction: living things reproduce.
- Evolution: living things evolve over time.
Hypothesis and Theory
- A hypothesis is a proposed explanation for a natural phenomenon based on observations or experimental studies.
- A theory is a broad explanation of some aspect of the natural world, substantiated by a large body of evidence.
Biological Organization
- The levels of biological organization are: atoms, molecules, cells, tissues, organs, and organisms.
- A cell is the smallest unit of biological organization that is considered alive.
Classification of Living Organisms
- Taxonomy is the grouping of species based on common ancestry.
- The three domains of life are: Bacteria, Archaea, and Eucarya.
- The kingdoms of life are: Protista, Fungi, Plantae, and Animalia.
Scientific Names and Genomes
- Binomial nomenclature is used to identify species, with a genus and specific epithet.
- A genome is the complete genetic makeup of an organism.
- Genomics is the study of genomes, and proteomics is the study of proteomes.
Scientific Method and Biology
- The scientific method involves observation, identification, experimental investigation, and theoretical explanation of natural phenomena.
- Biology is a scientific discipline that uses the scientific method to study life.
