Re: Herpetology B/C

Actually, birds are just not traditionally studied with reptiles because superficially they seem different. Phylogenetically, they are part of the clade Reptilia, which isn't a clade if you don't include birds. So even though they aren't studied together traditionally they are in the same monophylet...

Buy the tests. 3 min (tho I was in div b last year, you can buy the tests), 16 stations.

Re: Microbe Mission B/C

It is of the whole microscope. Apologies if I used the incorrect term.

Re: Microbe Mission B/C

Answer|Not quite. How I understand it, the half numerical aperture is an angle measurement, so the max value would be 90 (180 would be the max for the angular aperture, and would occur when the cover slip is touching the objective lens). So, it'll be larger than 2.745. To solve this pro...

Re: Microbe Mission B/C

Here's a question since this hasn't been posted on lately: A drop of immersion oil has been placed between the objective lens and cover slip in a compound light microscope. Given the index of refraction of the immersion oil is 1.515, the wavelength of light being used is blue (0.45um) and the resolu...

Re: Microbe Mission B/C

On the Wisconsin state exam, there was a calculation problem where you had to calculate the concentration of bacteria in the original flask given the serial dilutions done to it and how many bacteria there were on certain plates (after some dilutions were plated). I had read before that to calculate...

Re: Herpetology B/C

Rat snakes are pretty easy to identify as they have a sort of square-ish shaped head, keeled scales and a flat underside that makes the cross-section of their body look sort of like a loaf of bread.

Re: Rocks & Minerals B/C

can't see image but I think I know what diagram you're referring to, I think you're talking about the one showing the plagioclase and alkali feldspar solid solution series right?

Re: Rocks & Minerals B/C

adamantine luster and 6 perfect directions of cleavage (forming a dodecahedron). The streak is pretty interesting also, but you probably won't have a streak plate on the test (and you don't need it anyway because of the other properties). It's fairly soft (3.5-4) also. So even though it does have a ...

Re: Herpetology B/C

I usually use keeled/unkeeled scales, head shape, body shape, other distinctive body structures, etc. For example the genus Elaphe (rat snakes) have slightly keeled scales, a square shaped head and a slender but relatively sturdy looking body that looks like a loaf of bread in cross section (extreme...
