Evolution is the process by which populations of organisms change over generations through genetic variation and natural selection.
Unity and Diversity refers to the shared characteristics among all living organisms and the vast variety of life forms that have evolved.
Natural selection is the mechanism by which individuals with advantageous traits are more likely to survive and reproduce, driving evolutionary change.
The theme Structure and Function states that the shape of a biological structure is closely related to its function.
Scientific inquiry is the process of asking questions, making observations, forming hypotheses, conducting experiments, and drawing conclusions.
Observation, question, hypothesis, experiment, data collection, analysis, and conclusion.
A hypothesis is a testable and falsifiable explanation for a scientific question or observation.
A theory is a well-supported, broad explanation for a wide range of observations, while a hypothesis is a specific, testable prediction.
Controlled experiments isolate variables to test the effect of one factor while keeping others constant.
Emergent properties are new functions or characteristics that arise at each level of biological organization.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, biosphere.
Information flow involves the transmission and use of genetic information to control an organism's functions and development.
DNA is transcribed into RNA, which is translated into proteins that perform cellular functions.
Living organisms acquire and use energy to perform work, maintaining order and supporting life processes.
Homeostasis is the maintenance of a stable internal environment despite external changes.
Feedback regulation uses output signals to control processes, often through negative feedback to stabilize conditions.
Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
The tree of life illustrates evolutionary relationships among all living organisms based on common ancestry.
Peer review ensures research quality and validity by having experts evaluate findings before publication.
Qualitative data describes qualities or characteristics; quantitative data involves numerical measurements.
