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.
How do you plot negative latitude and longitude?
To plot negative latitude and longitude coordinates, use the correct format for the coordinates (e.g., (-12.345, -67.890)) and ensure that your mapping tool or software supports plotting negative coordinates. Most mapping tools will automatically recognize negative values and plot the coordinates accordingly.
What is the ICD 9 code for gram negative bacteria?
The ICD-9 code for gram-negative bacteria is 041.4. It is used to indicate infections caused by gram-negative bacteria in the coding system.

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.
Is it okay to be a serial killer?
No, it is not OK. Murder is never OK. A lifetime spent on negative behavior and negative thoughts is a life wasted. Killing a person is wasting someone else's life as well as your own. You only get one lifetime, use it to improve life for yourself and for everyone around you!
When do you use a negative rational number?
You use a negative rational number when an answer is below zero.
