The method of determining phage attention by dilution and plate with susceptible cells is named titering or the plaque assay. This process defines the number of viable phage particles in a stock suspension.
<h3>Dilution factor</h3>
First, we need to estimate the dilution factor. Three successive dilutions were made: 1/100 the first, 1/100 the second, and 1/10 the third part. The original stock was therefore diluted by 100,000 spans. One-tenth of one mL of the definitive dilution was plated, and 65 plaques occurred on the plate. Accordingly, there were 650 functional phage particles per mL (650 PFU/mL) in the final dilution. The authentic stock contained therefore 650 PFU/mL X 100,000 = 65,000,000 PFU/mL.

Egyptian civilization developed along the Nile River in large part because the river's annual flooding ensured reliable, rich soil for growing crops.
There is tens of thousands of years' worth of historical evidence of human presence in Egypt. In search of dependable water sources, human civilization's development into the Sahara drove people closer to the Nile River. The majority of settlement in the Nile Valley was restricted to an area just a few miles from the river itself, with the exception of the delta zone where the river expands out as it goes into the sea.
Because of how frequently the Nile River flooded, the ancient Egyptians based their three seasons—inundation (flooding), growth, and harvest—around it. Due to the fact that it consistently deposited a fresh layer of nutrient-rich soil, this annual flooding was essential to agriculture.

<span>Hale's description of Minnie Wright can be interpreted from a female point of view by focusing on how Wright would have been expected to act after the death of her husband. Wright does not act in this way, instead she was acting just in a state of shock.</span>
Answer:
Explanation:
This information would certainly make me confused as to what I should be believing. In addition to that, it would make it harder for me to trust scientists and the supposed theories and hypotheses they come up with. If the theory of plate tectonics wasn’t true, I would not be happy.
