#1 Connecting Science to Vet Tech Practice

Atom

The smallest component of an element that retains all chemical properties of that element; the basic building block of all matter.

Biological Hierarchy

A method of organizing living things based on emergent properties, from smallest to largest: atom → molecule → cell → tissue → organ → organism → population → ecosystem → biosphere.

Biology

The study of life, including anatomy, physiology, and development of living organisms; the scientific foundation of all veterinary medicine.

Biosphere

All living things on Earth and the ecosystems they depend on; the planet as a whole.

Cell

The fundamental unit of all living organisms; the smallest structure that can carry out all life processes.

Control Group

A group that continues under existing conditions and doesn't receive experimental treatment in research studies.

Controlled Variables

Factors or conditions in an experiment that don't change and are kept the same between groups.

Deductive Reasoning

Using general principles or broad observations to predict specific outcomes or make specific conclusions.

Dependent Variable

The result or outcome you measure in response to changes in the independent variable; also called responding variable.

Ecosystem

All living things and nonliving factors in an area and how they interact with each other.

Emergent Properties

New properties that appear at each level of biological hierarchy due to increasing complexity.

Experimental Group

A group exposed to the factor being tested in an experiment; receives the experimental treatment.

Hypothesis

A proposed explanation for a phenomenon or problem being studied, written as a testable statement.

Independent Variable

The variable that's purposefully changed in an experiment; what differs between control and experimental groups; also called manipulated variable.

Inductive Reasoning

Taking specific observations and drawing broader conclusions or general principles from them.

Inference

A conclusion drawn from an observation based on previous experience or understanding; an interpretation of what you observe.

Molecule

Two or more atoms bonded together; the smallest unit of a compound that retains its chemical properties.

Observation

A statement that simply describes a phenomenon you can see, hear, measure, or detect without interpretation.

Organ

Multiple tissues working together to perform specific functions; a distinct structure with specialized roles.

Organism

A complete living thing made up of organ systems working together; an individual life form.

Peer Review

The process of subjecting experiments and their results to scrutiny by other scientists in the same field before publication.

Population

A group of organisms of the same species that share an ecosystem and can potentially interbreed.

Primary Literature

Original research articles published by the scientists who carried out and verified the research; first-hand scientific reports.

Qualitative Data

Data that describes observations or characteristics using descriptive, non-numerical information.

Quantitative Data

Observations that are made or measured using numbers; numerical data that can be counted or measured.

Scientific Method

An organized process for solving problems including: making observations, asking questions, forming hypotheses, making predictions, designing experiments, collecting data, and drawing conclusions.

Secondary Literature

Articles that interpret, simplify, and summarize primary literature, such as review articles and clinical summaries.

Systems Biology

The study of organisms and how they interact with their environment and other organisms, focusing on how changes in one part affect others.

Tertiary Literature

General information sources like textbooks, blogs, and videos that distill information from both primary and secondary literature.

Tissue

Similar cell types grouped together to perform a common function; organized collections of cells working toward the same goal.

Variable

A factor, condition, or relationship that can be changed in an experiment; anything that can vary or be manipulated.
