(TESTQ) Bio Test 1

Flashcards covering key terminology, concepts, biological organization, scientific inquiry methods, and experimental variables for the upcoming exam based on the lecture transcript.

Hierarchy of Life

Also known as 'Life at its many levels,' referring to the 6 levels of biological organization in proper sequence from Chemical to Organism.

Processes of a Dynamic Ecosystem

The two major processes within an ecosystem, consisting of the cycling of nutrients and the flow of energy.

Prokaryotes and Eukaryotes

The two fundamental cell types exhibiting distinct structural characteristics.

Scientific Method

A formal process of inquiry involving seven structured steps.

Hypothesis

A proposed explanation for an observation, distinct from a comprehensive scientific theory.

Scientific Theory

A broad, well-substantiated scientific concept distinguished from a single hypothesis.

Deductive Reasoning

A form of logical thinking distinguished from inductive reasoning in scientific inquiry.

Inductive Reasoning

A method of logical reasoning that moves from specific observations to broader generalizations, distinguished from deductive reasoning.

Experimental Group

The group in an experiment that receives the specific treatment being tested, distinguished from the control group.

Control Group

The benchmark group in an experiment that does not receive the experimental treatment, used for comparison against the experimental group.

Null Hypothesis

A statistical concept evaluated alongside the main hypothesis and alternative hypothesis in experimental setups, such as the Olestra experiment.

Independent Variable

The variable in an experiment that is manipulated or changed, identified on a graph alongside the dependent variable.

Dependent Variable

The variable being measured or observed in an experiment, identified on a graph alongside the independent variable.

Qualitative Data

Descriptive, non-numerical data observed during inquiry, distinguished from quantitative data.

Quantitative Data

Numerical data involving measurements or counts, distinguished from qualitative data.
