In making a seial dilution we first take a 100 percent of a solution and pour what percentage in the next container

• 1 %

• 10%

• 50 %

• 100 %

• You can use various amounts depending on the experiment

When preparing a culure you will need the following equipment (multiple answers)

• A broth with the appropriate food for the bacteria

• A heating device

• scale

• deionzed water

• water bath

There are multiple answers for this question. When using a spectrophometer you find out the

• type of bacteria which is being scanned

• the peak wavelength

• percentage of water

• amount of absorbarance

There were 4 antibiotics used in the lab "Antibiotic Resistance". In the lab we tested these antibiotics against various types (species) of bacteria. How did we measure the results?

• You count each colony.

• You look at the reaction of the bacteria under a microscope

• You looked for a zone of inhibition

• You use an indicator to see if there are changes in color

Gram positive turns which color

• Red

• Orange

• yellow

• Purple
