0%
One that can resist being squashed
0%
One that is not affected by acids
0%
One that is not affected by antibiotics
0%
One that can resist an attack by a bacteriophage virus

Q.4.

How do these resistant strains of bacteria arise?

0%
Natural selection
0%

0%
Selective breeding
0%
Non-selective breeding

Q.5.

What is the outcome when a resistant strain of bacteria develops?

0%
Some diseases could become very difficult to control
0%
The bacteria will grow larger
0%
New types of antibiotic will need to be developed
0%
An epidemic

Q.6.

What part of the bacteria controls resistance?

0%
Chromosomes
0%
Nucleus
0%
Cytoplasm
0%
Genes

Q.7.

Why should you always complete a course of antibiotics?

0%
So that you don't waste the money spent on your prescription
0%
It is illegal not to finish the whole course
0%
It avoids wasting the antibiotics
0%
It kills off the maximum number of bacteria

Q.8.

Resistance to antibiotics is genetic. Why is this a problem?

0%
Resistance can be passed on to future generations of bacteria
0%
It means that resistant bacteria genes could become part of your genes
0%
You might become immune to the antibiotic
0%
It makes bacteria grow faster

Q.9.

What are doctors doing to slow down the development of resistant bacteria?

0%
Prescribing more antibiotics
0%
Prescribing longer courses of antibiotics
0%
Prescribing fewer antibiotics
0%
Not prescribing antibiotics

If these escape from the patient it is possible they can _______ others with bacteria that are not killed by antibiotics.
