Yes, each colony that forms on the plate was the result of a single microorganism. If you can know the quantity of the unit sample, you can know the number of microorganisms that were in that sample by counting the colonies.
Not really. It is likely that some microorganisms stick with each other, and is simply not separable by simple streaking. Sometimes the organisms exist in a bundle together, and all of these lead to the growth of one colony. Hence, microbiologist usually use the term "Colony Forming Unit" (CFU) to represent the origin of a colony, be it only one organism, or more than one.
indeed it really is my friend
you can get germs on virtually anything there is on the planet. microorganisms or "germs" as you called it have the characteristic of being UBIQUITOUS which means they are present everywhere. the good thing is that only a small percentage of the total population of microorganisms can really cause disease.
Petrification is the process of turning some plant material into stone without changing the original shape by the infiltration with water carrying mineral particles.
They don't so much disappear as become converted to a different isotope - as they throw off particles. If you took the remaining material and added the mass of the particles released as radiation, you should still get the same mass as the original material before the radioactive decay.

cause it was really not a major colony
Im not really all that sure but I have reason to belive either acetic acid in wine or yeast in bread is made up of microorganisms.
either a planned colony or a crown colony. I'm really not sure which one...sorry.
Raleigh had financed the colony at Roanoke. When the colony failed, he lost his investment.
not really it just reuses the material

food can be carriers of microorganisms. remember that food can serve as a good culture medium for these microorganisms to thrive. that is why to prevent such spread of foodborne diseases it is really important to wash the food thoroughly and to cook them properly.
Possibly but I really doubt it.
viruses are not really organisms
I really don't know.
they dont really make a sound. it is mainly a vibrating noise which i guess could be classed a a noise. :)
