Your foot is the same lenght as your arm (not including wrist or elbow)
I guess i'm part of that 75% because i did try to disprove it...

DA I think there are some of the answers to your questions were in the link I posted (http://curious.astro.cornell.edu/question.php?number=310). They recon that you weight about 0.5% more at the poles  The fingerprints of koalas are very similar to those of humans, so much so that they could be confused at a crime scene. (Don't ask me what a koala would be doing there, but anyway...) |

Gasoline is very effective in removing spray painted graffiti (i don't recommend you use this technique because it can be very dangerous for obvious reasons)
it's just one of those things i've picked up over the years

did you know that your fully extended arm span (if you reach your arms out sideways as though telling a fish story) from the tip of your middle finger, to the tip of your other middle finger. Is, give or take a few inches, your height.

People bleach rice, sugar, and some other food products befor selling them (you can get unbleached rice and suger which is more healthy for you but also more expensive) and trees use to have white bark, but because of air pollution it turned into a grayish color.

trees use to have white bark, but because of air pollution it turned into a grayish color. Starfire where did you see that? As far as I'm aware, many trees naturally have bark colours other than white. Edit: Actually I seem to remember something in genetics about the increase in the number of black vs white peppered moths, where there was an increase in black moths from the time of the industrial revolution because the soot was turning the trees a blacker colour. Is that what you meant? (The effect of this is generally lesser nowdays and not all trees do have white bark though) |

Yep, we studied it in science class, it was about evlotion and how moths were white but they had to evolve to survive. Sence they are a grayish color they can blend with the trees.
BTW, Some times you may see a white moth.

umm... that's not an evolution, 5% percent were black, because birds ate them, but because the trees were burnt or something(I can't really remember) the White began to stick out, and therefore the birds started to eat them, and Black moths started to thrive. they reproduced, and there were more Black moths. Simple.

Definition from Wikipedia: "The modern synthesis, "evolution" means a change in the frequency of an allele within a gene pool. This change may be caused by a number of different mechanisms: natural selection, genetic drift or changes in population structure (gene flow)."
The moth example is used to show an example of natural selection which presumeably resulted in a change in the frequency of the different alleles related to colour in the population. So I guess it could be seen as evolution.

Yes it is evolution, the tital of the chapter was called "Evolution", they had to change there body color to survive. Imgain if humans all changed color to purple to survive, well they can't just do it over night, it happens over time. Evolution is when somthing changes to best survive its habitat. 5% of moths were gray befor the evolution took place.
Main Entry: evo·lu·tion
Pronunciation: "e-v&-'lü-sh&n, "E-v&-

Starfire: There is no need to get defensive. They were just discussing the type of "evolution" and it is not that the individual moths changed color. The change is the result of moths with a particular trait surviving to reproduce while others with a different color were eaten before they reproduced. Thus the change in the overall population. Does this make any sense to you?

Yes, but when i know im right i like to prove it, expecily if it deals with science or animals. In this case it involved both so you can imgain how i felt.

My bro can lick his elbow... I'll try to get it on tape one day... So can my ex-girlfriend's mom (I'm being serious, lol). It's not impossible for everybody, just most people. |
