For the Microbial Diseases, let's use Chicken Pox as an example. I know that I need to know that it's viral caused, but do I have to know the specific name of the virus that causes it? Also, do I need to know the symptoms of it too?

What microscope would you use to view a pollen grain?
Scanning electron?
What's the difference between stereo and compound microscope?

TIA

Compound microscope has two lenses - i.e., ocular and objective. Stereo microscope has two oculars and two objectives - it's really two compound microscopes side by side.
And yes, those cool pictures of the surface details of pollen grains are SEMs.

When would you use a confocal microscope instead of a fluorescence microscope?

you don't need to know the particular virus but you would be safe to know the symptoms. Helped?

O.K. does anyone know a really good website to learn about conversions and microscopes becasue that we those were the only things that kept me frim a 1st place medal in regionals please please PLEASE

I think if you need higher magnification or have fluorescent-stained specimens, you'd use confocal. Confocal uses a laser, whereas fluorescence uses UV radiation and a shield that protects the viewer's eyes.

does anyone know where to find good practice questions on the internet? Thanks.

I found the "learn" version to be the most helpful.

Happy studying!

Our regional test was super easy - everything that was needed on it I learned in enriched molecular bio (not even AP! which I haven't yet taken btw). My partner and I finished in 20 minutes... then we had to focus a microscope and draw a picture from what we saw in as little time as possible. We must have had the shortest time, because there must have been more than one team that answered all of the rest of the test correctly. We left the room with 20 minutes to spare, after having thoroughly double-checked our work.

Hey guys, I'll be doing this at our regionals in 2 weeks, and I have a question. Do the tests usually just focus on the different types of microbes and diseases they cause, or do they also include specific information about each microbe? For example, would we only need to know what a virus is, or also virus reproduction, different types of viruses (retroviruses, DNA vs RNA viruses, etc), chemistry aspects of viruses, and evolution of viruses?
