You are doing an experiment involving antibiotic resistance in your study bacteria. This organism grows well on LB - Miller agar
KiRa [710]

Answer:

See the answer below

Explanation:

The stock solution of Gentamycin has a concentration of 5 mg/ml while each plate needs to contain 50 micrograms/ml of Gentamycin.

5 mg/ml = 5000 micrograms/ml

There is a need to dilute the stock antibiotic solution in order to arrive at 50 micrograms/ml. Using the dilution principle;

m1v1 = m2v2

5000 x 1 = 50 x v2

v2 = 5000/50 = 1000 ml

<em>Hence, in order to prepare 50 micrograms/ml, 1 ml of the stock Gentamycin should be taken and diluted with 999 ml of distilled sterilized water. 1 ml of the diluted Gentamycin will then be added to each agar plate while they are still in the molten form at a warm temperature.</em>

a sample of dna contains 20 percent adenine and 30 percent cytosine. What percentage of tymine would you expect to find.
romanna [79]
20 percent.

Since one strand is 20, the opposite that would connect with it (Thymine) would have the same amount so the total would be 100.

Hope this helps!
