Which groups of pathogens will antibiotics destroy?
Bacteria and fungi
Bacteria and viruses
Only bacteria
Why are antibiotic resistant bacteria able to spread so quickly?
The mutation makes them reproduce faster
Non-resistant bacteria die so there is less competition for food and space
They are able to use antibiotics as a food source
How does stopping a course of antibiotics before the end cause antibiotic-resistance?
The most resistant bacteria are the last ones to die
Although all the bacteria have died, they all come back
All the non-resistant bacteria have been destroyed by the antibiotic
What is in the clear zone around an antibiotic disc on a bacterial lawn agar plate?
Resistant bacteria
Antibiotic and no bacteria
Dead bacteria and no antibiotic
The area of the clear zone around an antibiotic disc is calculated using which equation?
Area =\(\pi \text{r}\)
Area =\(\pi \text{d}^{2}\)
Area =\(\pi \text{r}^{2}\)
What is a coronary bypass?
A small metal mesh tube placed in a blood vessel in the heart
A piece of vein grafted around blockages in a coronary artery
A tube to reduce blood pressure in a person with very high blood pressure
Which tests are part of the preclinical testing of a new medicine?

Tested on cultured human cells and then animals
Tested on animals and then on healthy volunteers
In a blind trial who does not know which people are receiving the medicine?
Only the patients
Only the doctors
Both the patients and the doctors
Why is it that cancer cells have antigens?
All cells have antigens
Cancer cells are a form of pathogen
All cancer cells cause an immune response
Why is monoclonal antibody therapy sometimes called 'magic bullet therapy'?
The antibodies can enter the cancer cells like bullets.
Monoclonal antibodies are attached to radioactive or toxic substances
The antibodies ensure the treatment is only delivered to cancer cells, and not healthy cells
