Kind of late, but I need 3 things clarified:
Have archea ever been known to be pathogenic?
What distinguishes algal protists from plantae?
Does alcohol kill all prokaryota?
Amazing how we can call up entire genomes or protein maps with a few keystrokes, yet no website can really explain the above issues in detail and clarity.

1. No archaea has been discovered to be pathogenic so far.
2. Algal protists are protists, that is, although they are eukaryotes, they lack specialized tissue and are organized more simply than plants. They also lack mitochondria.
3.This depends on what you are implying. Some prokaryotes actually produce alcohol through fermentation, but that's probably not what you're asking about. Alcohol, when concentrated highly enough (70%) or so, can actually break a prokaryotes cell wall and then denature proteins of the cell. However as you see on the labels of alcohol disinfectant and stuff, this only kills 99.9% of bacteria (or whatever). To achieve a sterile environment (no microorganisms) you must use a change in pH, temperature or some other method of making the bacteria unable to function.

I HAVE A QUESTION!
Ok, I hate studying fungi! But since I have to study for it to participate in this event;
What will I need to know about fungi?

What a generic question

Starters: Try and subscribe to an online database or get a book on Microbiology.
What'd I suggest you learn for starters:
Classification. Classification for fungi is rather complex and annoying
Anatomy. Fungi have all these weird structures that they use due to their lack of mobility
Diet: They "eat" in a weird way. Look up hyphae.
Ecological role: They form many symbiotic relationships. There's a lot to learn about those
Habitats: They live pretty much anywhere, except extreme conditions.
Reproduction: Spores are annoying, but you have to know a lot about those
Uses: We use fungi for a lot of stuff.
Diseases: They cause a lot of "mold" related infections and diseases
Hope I helped somewhat

Probably just things like types of fungi, the structure of fungi, some more important ones used in industry, symbiotic relationships, mycotoxins, etc.
Also by the way, what school do you go to?

Will the history of electron microscopes be on the test?

Almost definitely not. Just know the types and the characteristics of each.

Thx so much. Are diseases a huge part of the test?

That depends on who writes the test. I would expect them to be only about 10-20% though.

Looking back at the rules, what questions will be ask about growth curves and graph interpretation(really sorry about all these questions, tryouts for microbe mission is tomorrow

)?
