I think it's something to do with high oxidation potentially causing organ failure? Like said some sort of oxidative damage, that rings a bell? Not sure though.

Yes, that's certainly one good reason. Other reasons might include a decrease in cerebral perfusion, which is what I was reading about today.

Chalk, clay, talc... varying minerals are added for a variety of different finishes.

Ok well condensation is the phase change of gas to liquid, via cooling.
And if retrograde is meant the reverse direction in this case, then it's a code word for vaporization, or else it's condensation by a means other than cooling. Perhaps condensation achieved by decreasing pressure (creating a vacuum) or altering the volume of the container?

I think I know one of the bonuses (unfortunately, I don't know the main answer 
)
xRNA could be a molecule that is not only a replicator, but also catalyzes its own formation. Currently these two tasks are divided between DNA and proteins. You can't have one without the other - sort of a chicken and egg dilemma. The more fascinating thing that bears on this is that the mineral mica exhibits just the right sort of electrical and molecular properties to serve as a lattice for the initial formation of RNA. In fact, the architecture of DNA still has an architecture reminiscent of mica's signature.

Right on!
Your turn.
The significance of ribozymes to the origins of life is that it is a solution to the chicken-egg dilemma that Mr. Grimes mentioned, namely genetic material that can chemically act on its own kind.

That subject (chicken or egg) is good for debate, but I'm sure its been handled by the creationists on the relevant thread. Suffice to say though it's not possible to know the answer to that as things stand, so any theory is tenuous at best. What you can say is that obviously at some point chemicals developed the ability to form other chemicals from themselves, what point this became ultimately self replicating, we don't know? But we have some fairly good guesses. Suffice to say comparing modern DNA or cellular processes to primordial chemistry is misleading, something most creationists seem to forget. The precursor stages don't really exist, or at least we have no evidence for them. Unless someone knows of cases I haven't heard about which is highly likely, it's not really my area of expertise?

We have 3 types of cones in our eye: blue, green, & red.
Which cone is causing us to be fooled by this illusion?
(the middle-front and middle-top squares are actually the same colour)

I can't see colour, so I don't know what you mean by "brown".
Do those two squares look to be different colours/shades? (center-top and center-front)
edit: yes, why is it darker looking?
