Science 2.2.1 Flashcards
A drug that can kill or slow the growth of microorganisms such as bacteria.
antibiotic
A drug that slows the spread of a virus within a person’s body.
antiviral drug
Unicellular organisms that consist of prokaryotic cells and belong to the kingdom Bacteria. (Singular: bacterium)
bacteria
The force exerted by blood as it moves through blood vessels.
blood pressure
A disease caused by the uncontrolled division of abnormal cells.
cancer
A disease affecting the heart or blood vessels.
cardiovascular disease
A disease in which the body has trouble regulating its blood sugar level.
diabetes
Any abnormal or harmful breakdown in the body parts or functions of an organism.
disease
An occurrence of a disease in a community at an above-average rate.
epidemic
Mostly multicellular organisms that consist of eukaryotic cells and belong to the kingdom Fungi. (Singular: fungus)
fungi
The scientific theory that some diseases are caused by pathogens.
germ theory
A disease that can be spread from one individual to another.
infectious disease
An organism too small to be seen with the naked eye.
microorganism
A disease that cannot be spread from one individual to another.
noninfectious disease
A component in food that a living thing needs to survive and grow.
nutrient
An outbreak of a disease across a large geographic area.
pandemic
An organism that lives in or on another organism to obtain nutrients.
parasite
A living or nonliving thing that can infect an organism and cause disease. They include bacteria, fungi, parasites, and viruses.
pathogen
A poisonous substance.
toxin
A substance that is given to a person, usually by injection, to protect against an infectious disease.
vaccine
An infectious agent that can reproduce only by using living cells.
virus
Organic compounds that are found in fruits and vegetables. Needed for growth and development of healthy tissues such as skin, teeth, gums, and bones.
Vitamins
Inorganic compounds including iron and potassium. Needed for growth and development, as well as carrying oxygen and maintaining the body’s water balance.
Minerals
The most important nutrient, makingup between 50% and 65% of your body. Helps regulate your body temperature and makes up most of your blood and your cells’cytoplasm.
Water
A type of lipid found in nuts, seeds,fish, and vegetable oils. Used by the body to store energy and carry out important processes, including blood clotting and brain development.
Fats
Organic molecules that are made up of subunits called simple sugars. Store simple sugars that can be used by cells for energy.
Carbohydrates
Organic molecules made up of chains of subunits called amino acids. Regulate the activities of cells and are the major structural material of cells.
Proteins
