A nucleus consists of a nuclear membrane that surrounds it, within the membrane there is a nucleolus which can be compared metaphorically to the yolk of an egg in appearance. The nucleolus is surrounded by nucleoplasm which is quite like the cytoplasm.

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>

Hi Geny!
Question - Describe the cell theory and the developments that led to the cell theory.

- The basic unit of life is the cell.
- Cells are created from cells that had existed previously.
There were 3 scientists that made cell theory each of the 3 components of above were the 3 scientists.
- Mathia Schleiden discovered that plants were made of mainly cells.
- Rudolf Virchow discovered that cells are created from calls that had existed previously.
- Theodore Schwann discovered that animals were also made of mainly cells.
Hope This Helps :)
