marishachu [46]

Answer:

66 * 10^8 CFU/mL

Explanation:

Given -

a) Number of colonies of bacteria is equal to 66

b) Total volume of the solution is equal to 0.1 mL

c) Dilution factor is equal to 10^{-7}

As we know that

CFU/mL = \frac{N * DF}{V}

Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume

Substituting the given values in above equation, we get -

CFU/mL = \frac{66* 10^7}{0.1} \\= 66*10^8

suggest and explain how the flow of blood in a person with patent ductus arteriosus differs from that of a person with a healthy
iren2701 [21]
Ductus Arteriosus is a blood vessel normally present in fetuses during development. The blood vessel is designed to bypass the pulmonary artery and brings blood to the Descending Aorta, as the fetus cannot breath through the lung (being as they are fluid filled). This is normally not a problem because oxygenated blood comes from the mother's blood supply.

Patent Ductus Arteriosus, is what happens when that vessel does not close. While not as dangerous as other congenital defects. However, because there is still a bypass, blood that normally need to be oxygenated by going through the pulmonary arteries to the lungs, can be diverted and placed into the blood stream without vital oxygen. This condition may eventually lead to CHF (congestive Heart Failure) and Pulmonary Hypertension if not treated.
