You notice something is growing in a 100ml pot of liquid soap. You take 1ml of this liquid soap and perform a serial dilution and plate to determine the number of bacteria per 1ml in the liquid soap. On the 1:100,000 dilution you plate out 1ml and get a count of 37 colonies. How many bacteria were present in 1ml of soap (cfu/1ml)?

3'700,000 cfu

Explanation:

One way to count the amount of bacteria in a medium is by doing a dilution of the sample and count how many colonies growth. Each colony is a cfu (Colony forming units).

In the problem, you count 37 colonies. The dilution was 1:100,000. That means the bacteria present in the soap is:

37 colonies × (100,000 / 1) = 3'700,000 cfu

I hope it helps!

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
