Flashcards
Levels of Biological Organization
Levels of Biological Organization
A hierarchical system that describes how life is organized, from the smallest unit (atom) to the largest (biosphere). Each level builds upon the previous one.
Evolution
Evolution
The gradual change in the genetic makeup of a population over time, driven by natural selection.
Scientific Method
Scientific Method
A systematic approach to understanding the natural world, involving observation, formulating a hypothesis, testing it through experimentation, analyzing the results, and drawing a conclusion.

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
