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>
An observed consequence of higher water vapor concentrations is the increased frequency of intense precipitation events, mainly over land areas. ... Furthermore, because of warmer temperatures, more precipitation is falling as rain rather than snow.

C or D
Explanation:
but idk, i only know that eukaryas have membranes around nucleus and the other one doesn't
The answer is C. To decompose death animals.
<em /><em>That's a very important thing to be done in life. Can you imagine it, all animals death without being decomposed, left there for like years and years... That would be so smelly!
