Study Notes
Introduction to AP Biology
- Biology is the scientific study of life.
- Living things share characteristics:
- Organized into cells
- Acquire and use materials and energy
- Maintain homeostasis
- Respond to stimuli
- Reproduce
- Grow and develop
- Adapt
- Die
Big Ideas in Biology
- BI-1 Evolution: Explains life's diversity and unity.
- BI-2 Energy and Molecular Building Blocks: Examines energy and molecules in living things.
- BI-3 Information Storage, Transmission, and Response: Focuses on how information flows in living systems.
- BI-4 Interdependent Relationships: Shows the interactions between living and non-living components.
Big Idea 1: Evolution
- Organisms share basic characteristics, such as similar organization, DNA, and metabolic processes.
- All organisms are descendants of a common ancestor (LUCA).
- Evolution is change over time, driven by natural selection.
- Natural selection selects traits that enhance survival and reproduction in a given environment.
Big Idea 2: Energy and Molecular Building Blocks
- Organisms need energy to survive.
- Metabolism represents all chemical reactions in a cell.
- Energy flows through organisms; it starts with the Sun and is eventually released as heat.
- Chemicals cycle through organisms; they're broken down and reused.
Big Idea 3: Information Storage, Transmission, and Response
- Information examples include DNA, hormones, and neurotransmitters.
- Organisms reproduce, passing information to offspring.
- During development, organisms use information to grow and form.
- Genes contain instructions for biological form and function.
- Mutations are inheritable changes in genetic information.
Big Idea 4: Interdependent Relationships
- Life is organized from atoms to biospheres.
- Each level of organization exhibits emergent properties.
- Living things interact with each other and their environment (e.g., cooperation, competition).
AP Science Practices
- Communicating with Models: Using descriptions, visuals, and diagrams to explain natural phenomena.
- Using Mathematics Appropriately: Using mathematical tools to analyze data, probability, etc.
- Questioning Scientifically: Asking questions and formulating hypotheses.
- Collecting and Analyzing Data: Collecting and interpreting data related to a question.
- Justifying Conclusions and Theories: Presenting valid reasoning supported by evidence to draw conclusions.
- Expanding Understanding and Connections: Relating concepts to previous learning and outside knowledge (e.g., Chemistry).
The Scientific Method
- Observation
- Hypothesis (inductive reasoning to explain observed patterns)
- Predictions (deductive reasoning based on hypothesis)
- Experimentation
- Independent variable (tested)
- Dependent variable (measured)
- Control group
- Analysis of Data (including statistical analysis)
- Conclusions (rejecting/accepting hypothesis, modifying, or refining).
