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>

Answer:
Reduce, Recycle, and Reuse.
Explanation:
Reduce your use of single-use, disposable, and non-biodegradable items. By doing that, you may be able to decrease the amount of waste you produce on a daily basis.
Recycle your items wherever possible. Separate your items depending on those that can actually be recycled, and those that may not. Before you throw something in the bin as trash, make sure to think about whether the item can be recycled in its entirety or perhaps a part of it can.
Reuse your items as much as possible before you end up replacing them. Only buy essential necessities and choose your products wisely (preferably those with less packaging). Always look for items in your surrounding that can be reused.
Those three ways are very crucial when it comes to achieving sustainable living. At the same time, it helps humans reduce the amount of waste released into the environment.
