A student is assigned to measure the susceptibility of a strain of bacteria to 3 different antibiotics in Biology class. The student first divides the agar plate into four different quadrants, one of which is reserved for a Control. Which of the following best describes the purpose of the Control in this experiment?

a)

The Control quadrant is used to grow a different strain of bacteria so that you can compare it with the one you are testing.

b)

The Control quadrant helps demonstrate whether or not the same strain of bacteria grew correctly on the plate in the absence of any antibiotic.

c)

The Control quadrant contains all three antibiotics to show what completely inhibited growth would look like.

d)

The Control quadrant is the only quadrant on which no bacteria is grown and so that none of the bacteria comes in direct contact with the antibiotic.

9.

Over time, bacteria can become resistant to antibiotics. Why can this be considered harmful for humans?

a)

It is harmful to humans because all bacteria are bad and humans won’t be able to eat food with bacteria in it anymore.

b)

It is harmful to humans because when we get sick from bacteria that are resistant to antibiotics we won’t have anything to help make us better.

c)

It is harmful to humans because bacteria are only killed with antibiotics and if we don’t have antibiotics humans will get sick and die.
