Study Notes
Biology Exam Study Guide
- Biology Definition: The scientific study of life and living organisms.
Characteristics of Life
- Cellular Organization: Living things are composed of cells.
- Reproduction: Living things reproduce, creating new organisms.
- Metabolism: Living things use energy to carry out life processes.
- Homeostasis: Maintaining a stable internal environment.
- Heredity: Passing traits from parents to offspring.
- Response to Stimuli: Reacting to changes in the environment.
- Adaptation/Evolution: Responding to environmental changes over time.
- Growth and Development: Increase in size and complexity.
Scientific Method
- Observation: Identifying a phenomenon.
- Question: Asking a question about the observation.
- Hypothesis: Proposing a possible explanation.
- Prediction: A testable statement based on the hypothesis.
- Experiment: Testing the prediction.
- Analysis: Interpreting the results.
- Conclusion: Determining if the hypothesis is supported or rejected.
Hypothesis Format
- A hypothesis is stated as an "if...then" statement.
Units of Measurement
- Mass: Kilograms (kg)
- Length: Meters (m)
- Volume: Liters (L)
- Temperature: Kelvin (K)
Reading Graduated Cylinders
- To read a graduated cylinder, align your eye with the bottom of the liquid meniscus.
Lab Safety
- Review safety principles and emergency procedures.
Microscopy
- Compound Light Microscope: The microscope used in class.
