No, the solution with bacteria in it needs to be diluted in order to be in the range of 30 – 300.
A colony-forming unit –CFU is used to estimate the number of viable (ability to divide by binary fission) microbes in a sample.
A sample of microbes is diluted and spread on a plate. Then, the number of colonies is counted, assuming that each colony have grown from a single colony-forming unit, or CFU.
Plates with more than 300 colonies are difficult to count while those with less than 30 colonies give statistically unreliable numbers of colonies to count.

The overall (unbalanced) chemical equation for cellular respiration is: C6H12O6+O2→CO2+H2O+energy. Explanation: The balanced equation ...
Answer:
The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All living cells must carry out cellular respiration. Cellular Respiration uses ATP as energy.
Explanation:
The answer to the question above is letter D. <span>Chromosomes found in the cell nucleus.</span>
In the cell nucleus, DNA is tightly packed into the
thread-like structure known as chromosomes. Every chromosome is made up of
tightly coiled DNA around proteins (histones) that support its structure.
Chromosomes are not visible when there is no cell division. It cannot be seen
in the cell’s nucleus nor under the finest microscope. They are only visible
when the cell is dividing and is apparently visible under a microscope.
