Obviously, every cell in your body doesn't die simultaneously when the ability to have consciousness is lost. How long does it really take for all your cells--brain cells in particular--to die?

Are the Aborigines surviving Neanderthals?
I'm not trying to be racist it's a serious question I studied their history and they arrived in Austrailia 40,000 years ago and the Neanderthals didn't die off in Europe until 24,000 years ago. They look identical to Neanderthal pictures and I kind of feel like if scientists new their was a connection they wouldn't make it public to avoid hurting feelings. I mean their is documented proof of the existence of neanderthal/homo sapien hybrids so it is likely that their is a known connection. Aboriginals didn't arrive in Austrailia by boat secondly recent research shows that Neanderthals went extinct by interbreeding with the larger Modern Human population but Austrailia was seperated from the rest of the World. Furthermore recent DNA research shows that Neanderthals were a subspecies of Homo Sapiens and not a seperate species at all.

They say God created everything with a purpose, but I just can't figure out what purpose He had in mind for cockroaches. Seemingly nature's most abundant and hardy form of life, they're also one of the most useless and harmful, from my perspective; all they do is crawl around and spread disease. But if it's true that everything has at least one quality to recommend it, then the same has to be true of these obnoxious little bugs. What, then, are they good for?

Our science teacher gave us these questions on cells, I have no idea of how to answer them. Please help!

1. Enzymes control the rate at which chemical processes take place throughout the cell. Where are these enzymes made in the cell and how do they reach the parts of the cell where they are needed?

2. When examined under the electron microscope, a muscle cell is seen to have many mitochondria, how do you account for this?

3. Give arguments for and against a virus being a living thing.

Thank you sooo much for your time!
