Antibiotic Resistance Review

Front

Based on the figure, which antibiotic inhibited/stopped the growth of the bacteria the most? Options: A, B, C, D

Back

B

Answer explanation

Front

The area where bacteria cannot survive because of the antibiotic: zone of inhibition, zone of prohibition, the friend zone, zone of conjugation

Back

zone of inhibition

Answer explanation

To inhibit means to stop something.

Inhibition comes from the word "inhibit"

A zone is an area or space

Zone of inhibition is the area or space around the antibiotic where bacteria is not growing.

Front

How many antibiotics does the bacteria seem to be resistant to?

Back

3

Answer explanation

Resistant bacteria is not killed by the antibiotics. There are 3 antibiotics on the bacteria in the petri dish that seem to be unaffected by the antibiotics. There are two antibiotics that have a large area around them where no bacteria is growing.

Front

If you take antibiotics, the non-resistant bacteria die while the resistant bacteria survive and pass their antibiotic resistance trait to their offspring. This is an example of...

Back

natural selection

Front

Taking antibiotics when they are not needed can weaken the effectiveness of the antibiotics.

Back

True

Answer explanation

An antibiotic is a weapon that becomes weaker every time that it is used. This is why it is so important to avoid taking them when not necessary. Each time that an antibiotic is used, a small number of resistant bacteria survive, and these then prosper and multiply because they are the only ones able to do so.

How do bacteria develop antibiotic resistance?

Back

mutations & natural selection
