Pasteurized milk is allowed 20000 cfu ml how many colonies would be present if 1ml of a 10 -3 dilution was plated is 20000 cfu ml a health hazard?

20. No it is not a health hazard as raw milk has 50000 cfu/ml and can be consumed by humans.

Why dilution is a common approach employed by any pure culture technique?
the main purpose of this is to grow and isolate all bacteria present in an infection, to determine which of the bacteria that grew are most likely causing the infection and which are likely colonizers.
How could concentration of ions decrease with dilution?
ion cocentration donot decrease with dilution. it is the density of ions that decreases with dilution. because earlier the amt of ions that were present in an unit volume has been moved farther through dilution so at that unit volume we get concentration of ions less than previously it was, but overall the concentration of ions remain constant.
What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)?
This depends on the dilution ratio.
Why Tissue salts classed as vibrational medicine?
Tissue Salts may be regarded as "vibrational medicine" because of the extreme dilution of the mineral salt in the lactose or other carrier substance. For example a D6 dilution is a dilution of 1:9 repeated six times. The dilution is such that the quantity of the actual mineral salt present in the final titurated mixture can be regarded as being "in essence" only and that the effect of the medication is therefore vibrational. Personally I believe that the pathways by which tissue salts are absorbed - i.e via the membranes in the mouth and throat, is the crucial element in their effectiveness, and that the tissue salts themselves are somewhere between providing molecules of salt i.e. physical particles which are absorbed into the body, and vibrational medicine.
How did the continental US reach it's present size?
at first it started with the 13 colonies , then the settlers moved westward to California and stayed there .That is how the US reached it's present size

What unit of measurement is used for bacterial colonies?
Many aspects of bacterial colonies may be measured for example colony size or appearance can be useful. The measurement which is perhaps the most useful however, is the colony forming units per ml (or cfu) which indicates how many bacterial cells are present to form colonies on the medium. This is a relatively simple calculation which is done by initially counting the number of colonies present on the medium. this number is then multiplied by the inverse of the dilution used. For example, if the dilution of the bacterial broth was 10-2 and the number of colonies on the medium was 60, then the calculation would be 60 x 102. This result is then divided by the volume of sample used in ml and will give you the number of colony forming units per ml present on the medium. Ben McD
What is the present perfect tense of allow?
The present perfect tense of allow is "has allowed" or "have allowed," depending on the subject.

Why can't cheese be made with ultra-pasturized milk?
Ultra-pasteurized milk contains just about no bacteria. In order to make cheese, there must be the necessary bacteria present, either from slightly or normally-pasteurized milk or from raw milk.
Can pasteurised milk be consumed without boiling?
Pasteurized milk can be consumed without boiling because lactobacillus present in it.

This depends on the dilution ratio.

What does it mean for a product to have been pasteurized?
This means that the food has been treated in some manner to kill pathogens that may be present in it. This can be done with heat, chemicals, radiation, or pressure.
Why was there an English governor present in some of the colonies?
The colonies were subject to he English crown so the crown appointed Governors as the King's representatives in the colonies
In which present-day states were the new England colonies?
The answer is Sparta.
Did the middle Atlantic colonies have access to water?
Yes Of course all colonies had access to water. water was present in all colonies in every home as well.
