Answered Correctly.
What is a medical intervention? - Answer any measure whose purpose is to improve health
or alter course of a disease
What are the main categories of interventions that function to maintain human health? -
Answer treatments, diagnostic and equipment
How do scientists gather evidence during the potential outbreak of an infectious disease? -
Answer -recording patients' symptoms and find similarities with other patients
-isolate bacteria in a lab
- go to affected areas and determine the origin
- DNA sequences can be used to identify disease pathogens since they alter the DNA sequences
What is bioinformatics? - Answer The collection, classification, storage, and analysis of
biochemical and biological information using computers especially as applied in molecular
genetics and genomics.
How can DNA sequences be used to identify disease pathogens? - Answer They can find
genes that are associated with the pathogen
What is an antibody? - Answer An antigen-binding immunoglobulin, produced by B cells,
that functions as the effector in an immune response.
How do antibodies identify and inactivate antigens? - Answer - they use shape recognition
- the proteins of cells are configured to specific antibodies, so the foreign antigens bind to the
specific antibodies that inactivate them
How can the ELISA assay be used to detect disease? - Answer 1. primary antibodies attach to
specific antigen
2. secondary antibody attaches to primary antibody
3. when enzyme substrate is added, color change occurs
Why is it important for doctors to know the concentration of disease antigen present in a
patient's system? - Answer - explains how serious the disease antigen is
- the more the disease the easier it is to diagnose patients
, - also tells doctor how many other people have been affected before them, leading them to
patient zero
What steps do scientists take to diagnose, treat, and prevent future spread of a disease
outbreak? - Answer -symptoms are noted
-origin of pathogen is determined/incubation time
-tests like blood tests to determine antibodies & antigens
-preventative measure like quarantining
How do antibiotics work to fight bacterial infections? - Answer through efflux,
inactivation/destruction, and mutation
What methods do bacteria use to share antibiotic resistant genes? - Answer through
horizontal gene transfer mechanism (conjugation, transformation, trandsuction)
What actions are humans taking that are contributing to bacteria becoming resistant to
commonly used antibiotics? - Answer taking medicine when it isnt needed, or overusing
medicine, not finishing a cycle of antibiotics
How do frequency and amplitude affect how humans interpret sound? - Answer - Amplitude
- Measure of the height of the sound wave (energy) in decibels
Indicates how loud the sound will be
-Frequency - Measures the speed of the sound wave in hertz
Indicates the pitch of the sound
What are the different types of hearing loss? - Answer conductive and sensorinueral
How is hearing loss diagnosed? - Answer Rinne Test - Uses a tuning fork to compare sound
through vibrations to sound waves going through the outer ear. If the sound through vibrations
is longer that means there maybe conductive hearing loss.
Audiogram - Uses different frequencies to test the decibels patients can hear them in a sound
proof room
What interventions are available for patients with conductive hearing loss? - Answer surgery
and antobiotics
What is vaccination? - Answer a substance used to stimulate the production of antibodies
and provide immunity against one or several diseases, prepared from the causative agent of a
