Biology - September 2006

First off, I believe in evolution. Second, I've heard from many sources that some snakes have vestigial hip bones. This seems like a nail in the coffin of creationists. I mean, what excuse can they come up with for that? Problem is, I can not find a picture of a snake skeleton with a hip bone anywhere though. Does anyone have a link to a pic?

(A)A plant bends toward the light

When the homologous pairs line up, is it four separate chromatids that are lining up, and two go to each new cell? When you say that the homologous chromosomes separate, do they mean chromosome as in two chromatids or one?

I need to prepare an enrichment culture of Methylobacterium mesophilicum. I just read online, that I should use methanol as my only carbon source.
The ingredients I had originally thought about where:
5g peptone, 3g meat extract, 15g agar, 1000ml water, 1% methanol. I was also going to add 10 mg of MnSO4 for sporulation

Does anyone know? Please help
