Question

"Scientists will often grow bacteria in prepared petri dishes. In some experiments, the petri dish will also contain paper disks soaked in a particular antibiotic. The area where the bacteria do not grow is called the zone of inhibition, or ZOI. The diameter of the ZOI indicates the effectiveness of the antibiotic.

The ZOI data collected by one scientist while trying to determine which disk (A, B, C, or D) is most effective at killing Streptococcus bacteria are: Disk D–9 mm, Disk B–8 mm, Disk C–0 mm.

Insert the appropriate heading (with units) for the second column in the data table below and record the data from this investigation"

Answer 1

The appropriate heading for the second column in the data table would be:

Disk Type Zone of Inhibition (ZOI) Diameter (mm)

D 9

B 8

C 0

In a bacterial growth experiment, researchers cultivate bacteria in petri dishes, often incorporating antibiotic-soaked paper disks.

The region devoid of bacterial growth is termed the Zone of Inhibition (ZOI), with its diameter serving as a metric for antibiotic efficacy. The ZOI data, gauging the effectiveness against Streptococcus bacteria for disks A, B, C, and D, are as follows:

Disk D – 9 mm, Disk B – 8 mm, Disk C – 0 mm.

In the data table, the second column, titled "Zone of Inhibition (ZOI) Diameter (mm)," documents these measurements, emphasizing millimeters as the unit of measurement.

Answer 2

Since I can't physically insert the appropriate heading, with units, I'll make the data table below by using the information given.

Disk-----------Measurement of ZOI (mm) also acceptable is ZOI (mm)

A--------------13 ( +/- 2 mm)

B--------------8

C-------------0

D-------------9
