Androids and Boods have landed on Mars. Androids have green skin and Boods have 5 arms. 87% of all Androids are Boods. 3% of all Boods are Androids. There are 13 Androids that are not Boods. How many Boods are not Androids?

Please can you explain - you probably have to be real clever to get this, I'm not that good. Thanks everyone.

Yeah, as above. I've researched it and a lot of places came up. So does anyone know where Gneiss is mainly found
(Like a country e.g. America, UK, Australia)
And is there a landmark or something that is made of Gneiss?

For science fair, I'm considering doing a project with resistant bacteria. Basically, I would grow bacteria, then expose it to hand sanitizer, rubbing alchohol, or anti-bacterial soap. (Woo-hoo, IV) Whatever is left, I would reproduce and expose it again and again, to see how long it takes the bacteria to become resistant. (Woo-hoo, DV) There's just one problem. What would I do with the resistant bacteria when the experiment is done? How do I kill it off? Any biologists in here have any ideas?

why have all the animals in the world stopped evolving including man?
Common sense says, if we evolved, then we should still be evolving, right? if not, why? We are far from perfect, and the worlds climate is changing.
I don't see anyone developing anti ultraviolet skin because of the ozone hole, gills like water world if the polar caps melt away, or maybe some extra cooling organs for the global warming.
how can anyone believe this stuff, it doesn't follow any scientific logic, it contradicts itself. when are the scientist gonna come up with something that doesn't insult our intelligence? we can go to space, but we can't get our story straight on our own planet!

Hi,

Well I'm a high school student currently. I'm going to take geometry for my 9th grade math. I was wondering if I can finish a whole year of Algebra 2 during the summer?

Any help would be appreciated.

Thank You
