What is microbiology? science that explores microscopic organisms including viruses, bacteria, protozoa, parasites ,and some fungi and algae.
What is a protozoa? one-celled, animal-like protist that can live in water, soil, and living and dead organism. usually classified by how they move, can cause disease in other organisms
What is algae? autotrophic eukaryotic organisms that convert the sun's energy into food through photosynthesis but that do not have roots, stems, or leaves
Define unicellular single-celled
What is a host cell? living cell in which a virus can can actively multiply or in which a virus can hide until activated by environmental stimuli
What is AIDS? Acquired Immune Deficiency Syndrome, which results in a variety of infections and a breakdown of an individual's immune system over time
What is influenza? viral infection of the respiratory system characterized by chills, fever, body aches, and fatigue.
What is a common cold? a viral infection usually associated with swollen nasal mucous membranes and the production of fluid from the sinuses and nose.

What are vectors? mechanisms (other than a person) that spread disease without getting sick itself. Examples include rats, ticks, mosquitos, and soil.
What is an infectious disease? a disease that can be passed from one organism (person, plant, or animal) to another, safe handling, good hygiene, and various antimicrobial chemicals can be used to reduce the risk and provide treatment of these
What are microbial pathogens? disease causing agents
What is biomedical research? scientific studies to explain how microbes cause infectious diseases in both plants and animals
What is a cell culture? group of cells grown in a nutrient solution from a single original cell
What is a clinical trial? A biomedical or behavioral research study of human subjects designed to answer specific questions about biomedical or behavioral interventions (drugs, treatments, devices)
What is Industrial Microbiology? involves quality control in preventing growth and contamination of products leading to food spoilage, and the production of pharmaceuticals (medicines)
