Experiment - Correct Answer-A research study conducted to determine the effect that one variable has upon another variable. Independent Variable - Correct Answer-The variable that is varied or manipulated by the researcher. Positive Control - Correct Answer-Group expected to have a positive result, allowing the researcher to show that the experimental set up was capable of producing results. Control Group - Correct Answer-The group in an experiment where the independent variable being tested is not applied so that it may serve as a standard for comparison against the experimental group where the independent variable is applied.
Forensic Science - Correct Answer-The application of scientific knowledge to questions of civil and criminal law. Negative Control - Correct Answer-Control group where conditions produce a negative outcome. Negative control groups help identify outside influences which may be present that were not accounted for when the procedure was created. Dependent Variable - Correct Answer-The measurable effect, outcome, or response in which the research is interested. Hypothesis - Correct Answer-Clear prediction of the anticipated results of an experiment. Personal Protective Equiptment - Correct Answer-Specialized clothing or equipment, worn by an employee for protection against infectious materials (as defined by OSHA). Chromosome - Correct Answer-Any of the usually linear bodies in the cell nucleus that contain the genetic material.
Restriction Enzyme - Correct Answer-A degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA. Restriction Fragment Length Polymorphism - Correct Answer- Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes). Autopsy - Correct Answer-An examination of the body after death usually with such dissection as will expose the vital organs for determining the cause of death. Confidentiality - Correct Answer-A set of rules or a promise that limits access or places restrictions on certain types of information Coroner - Correct Answer-An official who investigates violent, sudden, or suspicious deaths Health Insurance Portability and Accountability Act (HIPPA) - Correct Answer-A comprehensive set of standards and
practices designed to give patients specific rights regarding their personal health information. Medical Examiner - Correct Answer-A physician who performs an autopsy when death may be accidental or violent. He or she may also serve in some jurisdictions as the coroner. Endocrine - Correct Answer-A protein hormone secreted by pancreatic endocrine cells that raises blood glucose levels; an antagonistic hormone to insulin. Glucagen - Correct Answer-A substance deposited in bodily tissues as a store of carbohydrates. It is a polysaccharide that forms glucose on hydrolysis Glucose Tolerance Testing - Correct Answer-A test of the body's ability to metabolize glucose that involves the administration of a measured dose of glucose to the fasting stomach and the determination of blood glucose levels in the blood or urine at intervals thereafter and that is used especially to detect diabetes.
Risk Factors - Correct Answer-any attribute, characteristic or exposure of an individual that increases the likelihood of developing a disease or injury. Symptoms - Correct Answer-A physical or mental feature that is regarded as indicating a condition of disease, particularly such a feature that is apparent to the patient. Type 1 Diabetes - Correct Answer-Diabetes of a form that usually develops during childhood or adolescence and is characterized by a severe deficiency of insulin, leading to high blood glucose levels. Type 2 Diabetes - Correct Answer-Diabetes of a form that develops especially in adults and most often obese individuals and that is characterized by high blood glucose resulting from impaired insulin utilization coupled with the body's inability to compensate with increased insulin production. Adenosine Ti-Phosphate (ATP) Carbohydrate - Correct Answer- A compound composed of adenosine and three phosphate groups that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis.
Amino Acid - Correct Answer-An organic monomer which serves as a building block of proteins. Calorie - Correct Answer-The amount of heat energy required to raise the temperature of 1 g of water by 1°C; also the amount of heat energy that 1 g of water releases when it cools by 1°C. The Calorie (with a capital C), usually used to indicate the energy content of food, is a kilocalorie. Carbohydrate - Correct Answer-A sugar in the form of a monosaccharide, disaccharide or polysaccharide. Chemical Bond - Correct Answer-An attractive force that holds together the atoms, ions, or groups of atoms in a molecule or compound. Chemical Indicator - Correct Answer-A substance (as a dye) used to show visually usually by its capacity for color change, the condition of a solution with respect to the presence of free acid or alkali or some other substance. Chemical Reaction - Correct Answer-Chemical transformation or change; the interaction of chemical entities.
Lipid - Correct Answer-One of a family of compounds including fats, phospholipids, and steroids that is insoluble in water. Macromolecule - Correct Answer-A type of giant molecule formed by joining smaller molecules which includes proteins, polysaccharides, lipids, and nucleic acids. Molecule - Correct Answer-Two or more atoms held together by covalent bonds. Monomer - Correct Answer-The subunit that serves as the building block of a polymer. Monosaccharide - Correct Answer-A single sugar molecule such as glucose or fructose, the simplest type of sugar. Nutrient - Correct Answer-A substance that is needed by the body to maintain life and health. Polysaccharide - Correct Answer-A polymer of thousands of simple sugars formed by dehydration synthesis.
Protein - Correct Answer-A three dimensional polymer made of monomers of amino acids. Polymer - Correct Answer-A large molecule consisting of many repeating chemical units or molecules linked together. 911 Operator - Correct Answer-Contact EMT and notify EMS Emergency Medical Technician - Correct Answer-Respond to 911 calls, give short term care, determine death (alive or dead) Crime Scene Investigator - Correct Answer-Examine and secure crime scenes Blood Spatter Analyst - Correct Answer-Collect physical evidence(blood), examine location & shape, determine type of weapon, determine direction of travel of a victim or suspect Nutritionist/ Dietician - Correct Answer-Asses patients' and clients' health needs & diet, develop meal plans, keep up with latest nutritional science research
