Explanation:
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.
Sickle cell anemia is caused by an abnormal hemoglobin in red blood cells. hemoglobin is the red pigment found in red blood cells for carrying oxygen.The abnormality arises from a genetic mutation in the DNA gene that codes for the beta chain of the protein called globin of which hemoglobin is made of.In the beta chain, the sixth amino acid called glutamine is replaced by another one called valine.<span>This one change in the amino acids cause the hemoglobin protein to behave abnormally, causing red blood cells to lose their normal spherical shape and become bent like a sickle, hence the name "sickle cell" anemia</span>
