Alright. I have about 8 labs due tommorow. I have been out a lot because of the flu, and what is suspected to be Kolidus. I have one lab I don't understand, and need help. It's from books, but I'd like to know if anyone knows it off hand.

1. Changes in elevation of the crust at places where bench marks were set up in the past.

2. Structures, such as bench marks and buildings, have shifted.

3. In some places, sedimentary rock, known to form under water, is found at high elevations.

4. In some places, layers of sedimentary rock are not flat, but rather tilted, folded, or broken.

5. Preserved remains of sea life in rocks found at high elevations.

6. The formation of geosynclines {shallow basins} indicate the crust seems to sink as sediment builds up.

That's half the sheet;;the other half I got. What needs to be done is to identify the evidence that indicates that the earth's crust moved, or is moving.

Major help needed, please!

It has always seemed to me that the answer to any number divided by zero was not zero, but infinity. It drove me crazy in math classes, because I hated writing down zero, when I was pretty sure that infinity made more sense.

Am I wrong on this? I'm no mathematician I know...

I've never seen any footage of chinchillas in their natural habitat and would like to know if any exists. I looked for David Attenboroughs email but didn't come across it.

be making the men turn gay? This question is with humour because I am not homophobic, but more seriously, I understand the effects of increased estrogen could be harmful to the eco system. Example male fish have been found with female organs. Could this be happening to humans in the gay sense???

OK, this is pissin me off...I've been at it for over 30 min and can't find anything in the book about it. I remember learning how to do this at some long lost point, but that was years ago. Can you tell me why I do what this does?

sqrt=square root
sq=squared

(4+sqrt(x-5))sq

Now I know when you take the square of a sqrt you get whatever was under the square root, but in this case you dont. I get something along the lines of 16 + 8(x-5) +xsqrt(x-5)

What the hell? I still have the square root? I'm so lost...and where did the 8 come in? ughh
