correct answers
medical intervention - 🔷ANSWERS 🖊✔✔a measure that is taken to improve health
or change the direction of how the disease progresses
What are the main categories of interventions that function to maintain human
health? - 🔷ANSWERS 🖊✔✔preventive, pharmaceutical, and surgical
How do scientists gather evidence during the potential outbreak of an infectious
disease? - 🔷ANSWERS 🖊✔✔Scientists gather potential outbreaks using
bioinformatics.
What is bioinformatics? - 🔷ANSWERS 🖊✔✔Bioinformatics is collecting, classifying,
storing,
and analyzing information.
How can DNA sequences be used to identify disease pathogens? - 🔷ANSWERS 🖊
✔✔DNA sequences are ran through a website or BLAST. The DNA is compares the
sequence to the human genome.
What is an antibody? - 🔷ANSWERS 🖊✔✔An antibody is what responds to the
immune response that is the antigen. The primary antibody binds with the specific
antigen during ELISA.
How do antibodies identify and inactivate antigens? - 🔷ANSWERS 🖊✔✔Antibodies
identify the antigens through their immune response. The antigens are inactivated
when they bind together.
How can an ELISA assay be used to detect disease? - 🔷ANSWERS 🖊✔✔An ELISA
assay is used to bind a primary antibodies to a specific antigens. Next, an enzyme-
linked secondary antibodies binds to the primary antibodies. Then, substrates are
added. If the enzyme combines with the substrate, the solution turns blue. This
shows there is a pathogen.
, Why is it important for doctors to know the concentration of disease antigen present
in a patient's system? - 🔷ANSWERS 🖊✔✔The doctors need to know the
concentration of the disease to know how progressed the disease is and how much
of the medical intervention is needed. The doctors can use a solvent to dissolve a
solute to form a solution. Then do a serial dilution to get to the point where it will kill
the pathogen.
What steps do scientists take to diagnose, treat, and prevent future spread of a
disease outbreak? - 🔷ANSWERS 🖊✔✔The scientists would perform ELISA assays
and determine the cause of the disease to help prevent the spread of disease and
an outbreak.
How do antibiotics work to treat bacterial infections? - 🔷ANSWERS 🖊✔✔Antibiotics
kill foreign bacteria in the human body to eliminate contamination from the human
body. There are four different kinds of antibiotic and they each do something
different to kill the bacteria.
Penicillin - 🔷ANSWERS 🖊✔✔disrupt making the bacterial cell wall
Tetracycline - 🔷ANSWERS 🖊✔✔prevent attachment of RNA to ribosomes, prevents
protein production
Fluoroquinolone - 🔷ANSWERS 🖊✔✔separates the DNA strands, prevent DNA
replication
Sulfonamide - 🔷ANSWERS 🖊✔✔prevents the production of folic acid, the building
block of DNA
What methods do bacteria use to share antibiotic resistance? - 🔷ANSWERS 🖊
✔✔There are 3 different ways bacterial cells share
resistance :
- Transformation: when one bacterium take DNA from a dead bacterium
- Conjugation: "cell sex" bacteria is in direct contact with another and the genetic
material is transferred.
