We could also have said the dilution factor was 1/10, or the dilution factor was.1.
I didn t think of that Well, we don t need to please understand me ii pdf mix up all 100 liters.
Hint: this applet previews the module on bacterial growth rates a bit.Mais eficiente e extremamente prático, o AutoCAD 2012 está repleto de novas funcionalidades para aplicação em seus projetos e designs de engenharia e arquitetura.Another hint : Multiply by the reciprocal of the dilution factor one more hint : Don t forget that we re only reporting 2 significant digits.When we said the diluted coffee was.After 1 day, I counted 27 CFUs on the petri dish.Nope, can t do it, this is too much to count 0,050,000 to 41,050,000 /- 50,000.11 still great sorry, still too hard to count 1:1,000,000 42 41,500,000 to 41,500,000 /- 500,000.1 not too bad easy to count,000,000 4 35,000,000 to 45,000,000 /-.Again, when we say about 490,000, we really mean more than 485,000 but less than 495,000.I need a hint : The students took a 1/10,000 sample, so what do they need to multiply.If you found this last problem easy, that s great.That would be pretty difficult with a pipette.This is pretty obvious when you re dealing with factors of 10 or 100, but could be trickier if you had to use less comfortable numbers.
In other words, not trillions, not millions, but hundreds of billions.
And clearly, this module is going to pick that method apart and pound it into the figurative whiteboard.
