I was on crunchyroll forum when I click on a link and it was a picture of a human body being cut up and dissect. How do the dissectors just cut up bodies like that and how can doctors operate on people? Just looking at the picture made me dizzy and nauseous

For chemistry class we're doing this project where we have to create new technology. I know that there are already contacts that block some UV rays, but our project is contacts that change into sunglass-like UV blocking lenses when exposed to sunlight. Similar to the transition glasses, only in contact form.
Does anybody have any ideas what the consequences of these lenses would be?
I can make up most of the positive ones, but I'm having a little trouble with the negatives.

I found a piece of scrap metal and it said "kahrite 8" on it. Does anyone know anything about this type of metal? I plan on scrapping it and I want to know the types of metals (i.e. nickel) it might contain. It would probably be used around high heat since it was found in a steel mill. I would appreciate any type of feedback. Thanks!

I keep doing this problem and my values keep canceling themselves out? So I was wondering if this is not possible to be solved. Can you do it and tell me what you get? If you are able to solve it can you give me a quick guide on how you got to your answer, thanks!

Here it is:

2x+3y=-2
4y+2z=-10
3x+5z=1

Thanks for helping!

How does genetic engineering prevent genetic diversity? I understand that it DOES, but I don't understand HOW. Always the HOW question.
