Study Notes
Key Terms and Definitions
- Science: Organized method of using evidence to understand the natural world.
- Observation: Collecting information about events or processes using the senses in an orderly manner.
- Data: Information obtained through observation or experimentation.
- Inference: Logical interpretation derived from prior knowledge or experience.
- Hypothesis: Proposed scientific explanation for observations.
- Spontaneous Generation: Hypothesis that life can emerge from nonliving matter.
Experimental Concepts
- Controlled Experiment: An experimental setup where only one variable is changed at a time to ensure accurate results.
- Independent Variable: The variable that is intentionally altered in an experiment.
- Dependent Variable: The variable that responds to changes in the independent variable.
Scientific Theories and Biology
- Theory: A long-tested hypothesis supported by a considerable amount of data.
- Biology: The branch of science focused on understanding living organisms and their interactions.
Fundamental Biological Concepts
- Cell: The basic unit of life, consisting of living matter enclosed by a barrier.
- Sexual Reproduction: Reproductive process involving the union of cells from two parents, leading to new organisms.
- Asexual Reproduction: Reproduction involving a single parent, producing offspring identical to the parent.
Life Processes
- Metabolism: The entirety of chemical reactions occurring within an organism.
- Stimulus: Any signal that prompts a response from an organism.
- Homeostasis: The ability of organisms to maintain stable internal conditions despite changes in the external environment.
Evolution and Measurement
- Evolution: The capacity of species to adapt and change over time for survival.
- Metric System: Measurement system based on multiples of ten, utilizing physical standards.
Microscopy Techniques
- Microscope: Tool designed to magnify small objects for detailed inspection.
- Compound Light Microscope: Utilizes light passing through a specimen with two lenses to magnify.
- Electron Microscope: Employs focused beams of electrons to create an image of the specimen.
Cell Analysis Techniques
- Cell Culture: Process of growing a group of cells from a single original cell in a nutrient-rich solution.
- Cell Fractionation: Method for breaking cells into smaller parts and separating these components for study.
