Answer:
The correct labels are :
Label A prophase
Label B metaphase
Label C anaphase
label D telophase
Explanation:
Mitosis, a method of cell division which complete in four different phases. These phases are prophase, metaphase, anaphase and telophase. In the given question the correct labels are: A-prophase; B-metaphase; C-anaphase and D-telophase. Mitotic division is begins with prophase in which chromatin threads condense and called chromosomes. During metaphase all the chromosomes get arranged in the central plane. In the anaphase, the sister chromatids of each chromosome gets separated and move to the opposite pole. In the telophase the spindle breaks from the chromatids and begins to disappear. The nuclear membrane starts to form around each of the daughter chromosomes.

Answer:
The current answer is b) bacteria need for proper growth and cannot make themselves.
Explanation:
An essential nutrient is one which is required to the cell for the proper growth from the environment because it cannot be synthesized by the cell itself.
Some essential nutrients that bacteria require for their growth are carbon, nitrogen, water, iron, inorganic salts, and many other molecules.
These nutrients should be given from an easily available source to the bacteria for their proper growth because these nutrients are required to perform essential metabolic activities and can not be synthesized by bacteria on their own.
