The ACN used was somehow contaminated with piperdine. The C18 started to come out of one of the columns, ruining it. I'm not sure if the pip could have caused this.

It's all bright yellow with a few long black tufts of hair sticking out. I live in Ohio and I've never seen one like this. Does anyone have any good links that I can go to to see pictures and identify it? Or does anyone just know what it is?

Okay, there's this story about a little dog who saves a kid from a rattle snake. The news is reporting that your dog can get the anti-venum before you go hiking for about $100.00 otherwise it costs $500.00 if they get bite without this serium.

Okay, so the news has also talked about humans getting bite and it costing $30,000.00 for each shot. Usually, the patient requires 4-8 shots.

So, why the price difference in medicine?

Is there a human shot that can be taken before getting bite, like for the dogs?

I know that x^-3 simplifies to 1/x^3...but when it gets to 6n^-1, I get confused. So I need someone to explain to me how that works and how I would figure out 3/2t^-2. And I know a lot of people on here hate when the kid just asks for the answers so if you dont want to give me the answer and would rather just explain it to me instead, that works :D Thanks!

Is this a myth? I understand somewhat the physics behind falling from heights, but this sounded ridiculous when I was a kid, and sounds even more ridiculous now.
Maybe I'm not remembering the theory as it was originally told.
