There are questions like that, but they usually just concern the origin of mitochondria and chloroplasts. Prokaryotes were engulfed by eukaryotes and eventually became incorporated into the cell.
Well, there are those models with virses too...

So no one has had questions that ask the microbial origin of the nucleus??

What are the differences between an image produced from a dry mount vs. a wet mount?

Also, when would you want to use a compound vs. stereo light microscope?

I was pushing that button on the top for like 30 seconds. :lol: But, seriously, we had no idea what it was, so I just wrote that it was a centrifuge and it separated the microbial cultures from the sample....and I'm 99% sure that's incorrect. So, if anyone can tell me what it was, I'd be eternally grateful. :mrgreen:
I don't remember exactly what it was called, but I know it had something to do with putting antibiotics on cultures of bacteria without contamination to observe the effects. I didn't actually see the device in question, but I did see a picture of a similar device when we took the test at home.

Also, using microscopes is fairly common- it is actually considered preferable to finding a picture of the microbe in question. The only unfortunate thing is how careful you have to be when observing the slide not to bump it at all. Also, it can be a pain in the neck when the samples are still alive and swimming around.

I don't think the nucleus even has a microbial origin...

Actually it does. It has the most proposed theories too. The most commonly accepted one is the syntrophic model.

It's the model that hypothesizes that an endosymbiotic relationship between an Archaea and a bacteria created the eykaryotic cell. It is supported by the fact that archaea and eukarya have similar genes for proteins and possess kinases and G proteins similar to eukaryotic cells.

What kind of resource are you currently using? I bought Brock's Biology of Microorganisms (13 e/d) and had been studied with it. Is reading college-level microbiology textbook is necessary to win all the way up to the national level (assuming the school proceeds to the national level)?

Can you tell me any online website that you are using to study Microbe Mission?
