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

Answers questions . why are estuaries, such as the pamlico estuary, so important? . how would you be able to determine from whe
GaryK [48]
Estuaries, often reffered to as the nurseries of the sea provide feedind habitats for many aquatic animals and plants. Fish and shellfish commonly eaten in the U.S such as oyesters and Salmon complete almost half of their lifecycles in estuaries. Due to its shallow water,Pamlico estuary especially provides opportunities such as Fishing, crabbing and watersports as well.
We can be able to determine this concept by basing our facts on two concepts. Nutrient Influx, upon reaching the estuarian ecosystem, the nutrients in the presence of sunlight undergoes photosynthesis and produce phytoplanktons. Basically, where there is sunlight, we can assume there is a nutrient influx. Presence of Phytoplanktons will in turn help attract animals such as fish. Also, another contribution of nutrient influx is manure produced by the animals

Sewage treatment plans and fertilizer runoff. Auto emissions of nitrogen, fertilizers applied on golf courses and home gardens can contribute. Some plankton species may produce toxins that might cause these outbreaks
