I kept it on top of my buffet. One day it fell on the floor all by itself. It was broken in half. The strange thing is, it didn't break because of the fall. One half was still on top of the buffet. Any explanation for this?

I see lots of people that still use the terms venom and poison incorrectly. I will award 10 points to the person who gives me a description of these two different toxins closest to my own definitions of them. Im not looking for internet references, I want just the simplest descriptions of function for each.
Good luck!

On the interent it says you need one-two basic courses in biology and one-two basic courses in chemistry to become an peditrician what does that mean?

I heard that it was possible for plants to send chemical messages to each other via spores... has anyone else heard about this process- perhaps some of you are already talking to them, I don't know... what kinds of things do plants say?

Meteorologists and scientists need only reply.

Why can't we take a hotbed like Texas was over the winter, burning and blaxing with wildfires, or drought-ridden areas, and fly sorties of C5s filled with H2O from the Gulf of Mexico and drench the land?

Why couldn't we have saturated Easter Africa in the '60s, '70s, '80s, Biafra, Ethiopia, etc., with water?

Water has a cooling effect. Wouldn't it help in heat waves, droughts, fires?

Would it upset the fragile balance of our ecosystem?

I highly recommend the Life Magazine special edition on newstands right now, "Nature's Extremes." Some stuff scares me worse than radical Islam... and Christianity, for that matter.

For all of those that are well versed in biochemistry techniques I need some help in determining the ideal protocol for my research. So I am trying to determine a specific protease which degrades a receptor molecule that my lab studies but I am starting completely blank. So I thought that I should perform a DNA Microarray to determine gene expressio but I was wondering if anyone knows any other protocols which would allow me to view gene expression of many genes?

Can they just die of old age? Or will they always die a "violent" death, e.g. being swatted, stuck on fly paper or eaten by a bird?

My lecturer told us GM foods are not dangerous, that they take a gene from one plant and add it to another plant. Isn't this just speeding up evolution. Modifing a wheat plant that can feed millions in 3rd world countries can only be beneficial.

Is it possible that a physical universe (or all universes -in the case that there are parallel universes) exists only to complete the temporal evolution of all possible states in the specified universe when the rules of evolution (laws of physics) are subject to the constraints imposed by Goedel's Incompletenes Theorems?? (Ignore the paradoxes found by G. Cantor in developing Set Theory.)

I'm getting quite fed up with all of this Intelligent Design/creationist mumbo jumbo. I challenge you guys to come up with some good arguments that prove the ID "theory".
I AM NOT ASKING FOR ARGUMENTS AGAINST EVOLUTIONISM THIS CONCERNS ID ONLY!!! PROVING ONE THEORY WRONG DOES NOT PROVE ANOTHER THEORY RIGHT !!!

I'm a future Catholic Priest and I am, as a logical human being a supporter of Evolutionism, as is the Vatican.

P.S. The bible does not count as a scientific text, it was written by humans and tells us how we can live together and can answer religious questions, not scientific ones.

I know the answer is x^2=-6y (or that is the given answer), but I need to know how they got it. Thanks.

PS, the vertex is 0,0. My professor didn't go over this at all and if I see one worked out I'm sure I can do the rest. TIA
