Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.

In the use-dilution test a chemical is evaluated by its ability to kill 10 6 to 10 8 dried Clostridium sporogenes or Bacillus subtilis endospores Why is this considered a stringent test?
A measure of determining the effectiveness of a disinfectant using serial dilutions. definition found in intro to microbiology by Tortora, Funke, and Case.
What is the best use of negative staining?
size and shape
What is a ten fold serial dilution?
Serial dilution is usually 1/10 dilution. Therefore after a series of dilutions, you have a logarithmic curve of concentration (log10). Basically, if diluting 1/10 and starting off with 1 molar solution, first dilution = 0.1M, 2nd = 0.01M, 3rd = 0.001M. If making a 0.001M solution involved weighing out 0.005g of a salt for example, the error in making this solution out would be very large in comparison to weighing out 5g (1M) and diluting it 3 times by serial dilution. The benefit of it is mainly accuracy.

In the use-dilution test a chemical is evaluated by its ability to kill 106 and 108 dried clostridium sporongenes or bacillus subtilis endospores. why is this considered a stringent test?
Chemicals do not readily penetrate bacterial endospores. The number of endospores used is higher than would be expected in normal use of disinfectant. It uses a measure of determining the effectiveness of a disinfectant using serial dilutions.
How do you decide what operation you use to solve a problem?
Use BIDMAS meaning order of operations are brackets, indices, division, multiplication, addition and subtraction
How use the rules of indices to simplify the formulae below A4 x a8?
a4 x a8 = a22 x a23 = a25
When should you use PIMDAS in math?
It is the order of operations involving a mathematical problem which includes brackets, indices, multiplication, division, addition and subtraction.
When do you use a negative numbers?
You use a negative rational number when an answer is below zero.
When do you use a negative rational number?
You use a negative rational number when an answer is below zero.
Why do you use negative numbers in Math?
You use negative numbers to represent subtractions (10-5 is same as 10 + -5) Also, you use these to represent things that can be negative.
