What does the term biophotonics refer to?
A)Biophotonics refers to the coordinated efforts used to track, research, and reduce the specific health problems within a population.
B)Biophotonics refers to all procedures and devices using light technologies to study and work with living systems.
C)Biophotonics refers to the process of providing medical care by injection or digestion of vaccines to provide immunity against a disease.
D)Biophotonics refers to the study and prevention of pathogens using advanced technology.
2
What are pathogens?
A)Pathogens are a type of white blood cell; they are a part of the body’s first response to a disease.
B)Pathogens are a type of vaccine injected into the body to help increase the number of white blood cells to fight diseases.
C)Pathogens are agents that cause, and help spread, infectious diseases.
D)A pathogen is considered to be any foreign material in the body that triggers and stimulates the response of phagocytes.
3
What is the difference between a pathogen and an antigen?
A)Pathogens are agents that cause disease. Antigens are disease-fighting molecules.
B)Pathogens are agents that cause disease. Antigens are proteins on the surface of pathogens.
C)Antigens trigger a response from the body to send out white cells and other disease-fighting molecules, such as pathogens.
D)Pathogens trigger the production of phagocytes. Antigens manufacture specialized proteins called antibodies.
4
What are antibodies and what is their purpose in the immune system?
A)Antibodies are a part of the immune system. They manufacture white blood cells to fight the infection of diseases.
B)Antibodies are a type of white blood cell. They are manufactured by the immune system to fight diseases.
C)Antibodies are specialized proteins that identify and attach to antigens to prevent infection from diseases.
D)Antibodies help detect the presence of pathogens and then send a signal to the bone marrow to produce disease-fighting molecules.
5
Which statement is true about public health strategies?
A)Public health strategies can only be applied to the detection and prevention of infectious diseases.
B)Public health strategies do not include cancer screening programs because cancer is a non-infectious disease.
C)Public health strategies include all types of methods used to track, detect, and prevent all types of infectious and non-infectious diseases.
D)Preventative measures, such as not smoking cigarettes or staying out of the sun to avoid cancer, are not considered to be public health strategies because there is no guarantee that each person’s body will react in the same way.
6
What is the purpose of cancer screening?
A)Cancer screening is used to detect damaged cells in the early stages of the disease so that it can be treated effectively.
B)Cancer screening is the process used to determine whether the body has enough antibodies to fight against the disease.
C)Cancer screening pinpoints the exact location of the cancer cells and removes them before the disease spreads to other areas of the body.
D)Cancer screening helps determine how infectious the cancer cells inside the body are to the general population.
