B3: Quiz 7 – Answers
1) Antibiotics only kill bacteria. Measles is a virus, which means that we cannot use antibiotics to treat it
2) Painkillers or anything like that
3) Viruses reproduce in our bodies by invading our cells. This makes it hard to develop drugs that fight off viruses because it is tricky to just kill the virus and not kill our cells that the viruses have invaded
4)
a) A bacterium being antibiotic resistant means that the bacterium will not be killed by certain antibiotics
b) The number of antibiotic resistant strains of bacteria is increasing
5)
a) Plants
b) Willow
c) Digitalis comes from fox gloves and it is used to treat heart conditions
d) Penicillin was discovered from the microorganism called penicillium notatum (a type of mould). Penicillin was discovered by Alexander Fleming
e) Synthesised/ made in labs
f) The rainforest has thousands of plant species that pharmaceutical companies can look at to find new chemicals that may be able to be used to treat certain diseases
