Body Systems
The biological system responsible for gas exchange, primarily the intake of oxygen and the removal of carbon dioxide
What is the respiratory system?
This molecule, often collected from hair, blood, or saliva, contains the genetic blueprint unique to each individual.
What is DNA?
This common device is used to listen to heart and lung sounds.
What is a stethoscope?
This is a disease caused by an uncontrolled division of abnormal cells in a part of the body.
What is cancer?
This is a testable prediction often written in “If...then...” format before conducting an experiment.
What is a hypothesis?
The “bad” cholesterol that can build up in the arteries and help form plaques, which can cause coronary artery disease.
What is LDL (Low Density Lipoprotein)?
These three basic fingerprint patterns are the most commonly found on crime scenes.
What are loops, arches, and whorls?
This is a law passed in 1996 that establishes federal standards protecting sensitive health information from disclosure without patient's consent.
What is HIPAA?
This is the ability of bacteria to withstand the effects of antibiotics
What is antibiotic resistance?
What is an independent variable?
This is a protein produced by B cells in the blood; works to impair pathogens. Also called an immunoglobulin.
What is an antibody?
This is a laboratory technique used to separate molecules, like DNA, RNA, and proteins, based on their size and charge by passing an electric current through a gel
What is gel electrophoresis?
This is a tool that measures blood pressure.
What is a sphygmomanometer?
A form of diabetes that develops especially in adults, most often obese individuals. It is characterized by high blood glucose resulting from impaired insulin use coupled with the body’s inability to compensate with increased insulin production.
What is Type II Diabetes?
A group or condition where you expect a positive, known, effect. It helps verify that your experimental setup is actually capable of detecting the outcome you're testing for.
What is a positive control?
A type of vessel that carries blood from the heart through the body; part of the circulatory system.
What is an artery?
These are proteins that cut DNA at specific recognition sites, creating fragments with defined ends.
What are restriction enzymes?
These are measurements—specifically pulse rate, temperature, respiration rate, and blood pressure—that indicate the state of a patient’s essential body functions.
What are vital signs?
This is a genetic condition caused by the presence of an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the usual 46
This type of bias occurs when a researcher’s expectations influence the results of a study.
What is experimenter bias (or observer bias)?
This is a red protein responsible for transporting oxygen in the blood of vertebrates.
What is hemoglobin?
This is a laboratory technique used to amplify, or make copies, of a specific segment of DNA
What is PCR (Polymerase Chain Reaction)?
This is the top number in a blood pressure reading, representing the pressure in your arteries when your heart beats and pumps blood
What is systolic blood pressure?
This is a type of virus that uses its own RNA as genetic material and can convert it into DNA within a host cell. This DNA can then be integrated into the host cell's genome, allowing the virus to replicate and potentially cause disease.
What is a retrovirus?
This type of variable is not intentionally studied but may affect the outcome of the experiment, making results less reliable if not controlled.
What is a confounding variable?
