Study Notes
Chapter 1: Biological Organization
- Biological organization levels, from lowest to highest: atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere
- Give examples of each level
Evolution and Unity/Diversity of Life
- Evolution explains the unity and diversity of life on Earth
- Describe how the process of evolution works, relating to common ancestry and natural selection
Three Domains of Life
- Prokaryotic domains: Bacteria and Archaea
- Eukaryotic domain: Eukarya
- List the major characteristics of each domain
Eukarya Domains
- Four major life groups within Eukarya: Protists, Fungi, Plants, and Animals
- Describe the major characterisitics of each group: e.g., mode of nutrition (autotrophic/heterotrophic), cell structure (multicellular/unicellular)
Scientific Method
- Purpose and steps of the scientific method: observation, question, hypothesis, experiment, analysis, conclusion, communication
- Explain that a valid hypothesis is falsifiable, meaning it can be proven wrong in an experiment
- A scientific theory is a well-supported explanation
Experimental Design
- Define and explain the following terms related to experimental design:
- Control group: the group that does not receive the experimental treatment
- Experimental group: the group that is being tested
- Independent variable: the factor being changed in the experiment
- Dependent variable: the factor being measured in the experiment
- Sample size: the number of subjects in the experiment
- Repeatability: the ability to replicate the experiment with similar results
