Study Notes
Chapter 1: Introduction to Biology
- Science: An organized approach to understanding the natural world.
- Inference: A logical assumption based on existing knowledge.
- Hypothesis: A testable explanation for observations.
-
Scientific Method: A process for investigating the natural world:
- Observations
- Hypothesis formation (if-then statement)
- Controlled experiment design (one variable change at a time)
- Data collection and analysis
- Conclusion drawing
- Controlled experiment: An experiment where only one variable is changed, while others remain constant.
- Independent variable: The variable that is intentionally changed.
- Dependent variable: The variable that changes in response to the independent variable.
- Control group: A group that does not receive the treatment (remains unchanged).
- Biology: The study of life.
- Cells: The fundamental unit of life.
- Evolution: Change in species over time.
- Homeostasis: Maintaining a stable internal environment.
- Stimulus: A change in the environment that triggers a response.
- Metabolism: The sum of all chemical processes in an organism.
-
Eight Characteristics of Living Things:
- Composed of cells
- Based on a universal genetic code
- Obtain and use materials and energy (metabolism)
- Grow and develop
- Respond to their environment
- Change over time (evolve)
- Maintain a stable internal environment (homeostasis)
- Reproduce
Chapter 2: Chemistry of Life
- Atoms: The fundamental unit of matter.
- Atom structure: Protons (+), electrons (-), neutrons (neutral).
- Atomic number: The number of protons in an atom (determines the element).
- Atomic mass: The sum of protons and neutrons.
- Water molecule: Composed of two hydrogen atoms and one oxygen atom.
-
Water properties:
- Polarity: Uneven distribution of charge, making water a polar molecule.
- Hydrogen bonds: Weak attractions between partially positive hydrogen atoms of one water molecule and partially negative oxygen atoms of another.
- Cohesion: Attraction between water molecules.
- Adhesion: Attraction between water molecules and other substances.
- High heat capacity: Water absorbs a lot of heat before changing temperature.
- Solvent: Water's ability to dissolve many substances.
Chapter 3: The Biosphere
- Ecology: The study of interactions among organisms and between organisms and their environment.
- Species: A group of organisms that can interbreed and produce fertile offspring.
- Population: A group of the same species living in the same area.
- Community: All the populations that live in a defined area.
- Ecosystem: All the living (biotic) and nonliving (abiotic) things in an area.
- Biosphere: The part of Earth that supports life.
- Biome: A group of ecosystems that share similar climates and organisms.
- Abiotic factors: Non-living components of an ecosystem (e.g., sunlight, water).
- Biotic factors: Living components of an ecosystem (e.g., plants and animals).
- Primary consumers: Organisms that eat producers.
- Photosynthesis: The process where plants use sunlight to convert water and carbon dioxide into sugar (glucose) and oxygen.
