medical interventions - correct answer______ ______ can be:
-prescriptions
-medical/diagnostic procedures
-therapeutic
-communication
bioinformatics - correct answerDefinition
-The field of science that combines biology, computers and information technology to
store and analyze genetic data
-Can be used to help identify infectious agents, such as viruses and bacteria, involved
in disease outbreaks
way for scientists to gather evidence during outbreak - correct answerThe listed below
is a ____________ (8 words).
-Samples of blood, urine, and lymph are collected and are sent off for diagnostic
laboratory tests.
-Collaboration with the molecular biology department at the college to identify
pathogens by their DNA sequences
-The lab isolates primers and sends samples out for molecular testing
primer - correct answerDefinition
-A short piece of DNA or RNA that is complementary to a section of template strand and
acts as an attachment and starting point for the synthesis strand during DNA replication
gene variations - correct answerDNA sequences can be used to I.D disease pathogens
because _____ ______ can be revealed through database searches.
antibody - correct answerDefinition
-Protein manufactured by body to fight against foreign substance
, -Binds w/ foreign substance, inactivates them, allows other body processes to take
over/destroy/remove foreign substances
apoptosis - correct answerAntibodies complete ______ in order to bind to antigens.
However, antibodies need T-cells, which destroys antigens that have been tagged by
antibodies/cells that have been infected/changed, to help destroy it.
Enzyme-Linked Immunosorbant Assay/ELISA - correct answerDefinition
-Combines targeted tagging with antibodies and an enzyme reaction that produces a
color change to test for the presence of disease antigens or antibodies produced in
response to that antigen.
-Can detect disease agents in body fluids before the body has a chance to mount an
immune response and produce antibodies.
-Provides qualitative results (indicates whether a patient is positive or negative for the
presence of the antigen or antibody) and a quantitative results (indicates how much of
the detected substance is present)
amplitude - correct answerDefinition
-amount of energy in a sound wave
-increase energy in waves means an increase in ____ the louder the sound seems
frequency - correct answerDefinition
-how rapidly the sound waves vibrate per second
-increase ____ of sound mean the more the waves will vibrates and the higher the
sound's pitch
sensorineural - correct answerDefinition
-Occurs when there's damage to inner ear (cochlea) or to the vestibular nerve pathways
from inner ear
-chem.problem--> something's wrong w/ transmission
conductive - correct answerDefinition
-Occurs when sound isn't efficiently moved through outer ear canal to ear drum &
ossicles of middle ear
-Mechanical problem
hearing aid - correct answerType of Medical Intervention
-Assists in CONDUCTIVE hearing loss
-Allows the sound to travel over error in structure and continue journey to forming sound
cochlear implants - correct answerType of Medical Intervention
-Assist in SENSORINEURAL hearing
-Attempts to fix the chem. malfunction in ear
vaccination - correct answerDefinition
