Jeje I have another question; the women have 2 chromosomes X (XX) and the men have a chromosome X and one Y (XY), according to what I have read, says that to begin of the times the chromosome Y it has reduced its size, this chromosome it’s the one that determines that the one born is boy, that is I think, my questions are:
1)Is true that?
2)And if decreases until no longer to exist, will no longer born more baby boys?
3)Will that have some solution?
Sorry if you don't undertand this post sweatdrop and I will be grateful if you correct me and respond me my doubts 3nodding .

I don't understand Q's 1 and 3, but I can answer 2. There will always be a 50% chance that a baby born will be a boy. Seeing as how the male Haploid cell will ALWAYS have a Y Chromosome and an X Chromosome, and a female Haploid cell will always have 2 X Chromosomes, if you do a punnet Square of the 2 you will find that there will always be a 50 % chance of a bay being born that it will be a boy. And yes the Y Chromosome is smaller than the X chromosome.....It was still hard to really understand what you were asking so I hope that helps some. I'd love to Answer in more detail but like said it's difficult to understand what you're asking, sorry.

k ryoko-
Question 1: Yes it is true that the y is smaller than the x, but they aren't still getting smaller.
The problem is not whether the chromosomes are smaller, but that the sperm carrying the y chromosomes are more fragile. Many women attempt to predict the gender of their babies by when in their cycle the sperm is introduced. If it is too soon, the smaller male sperm have a lesser chance of survival and you are more likely to get a female baby. The males are faster than the female ones, so if it is later in the cycle, you have a better chance at a male since they can get there first.
Question 3: Since males are not being eliminated, there is no need for a solution.
Hope this answers the questions not already addressed!

* Sigh * Ok, I've been plagued by this little math problem today, I'm pretty sure I couldn't get the right answer because I'm only operating on 4 hours of sleep today and I also had to work....Sorry I had to write it out and post it because I don't know how you would type the symbols. xp  here we go, I started with the above function, and tried to simplify it into a powers series form, but the form is incorrect(that's the second part you see.)....Like said I'm pretty sure it was just a simple math mistake that gave me the wrong answer, but if anyone knows how to do this could you by chance solve the problem for me? I'm curious as to what the answer is, but I'm way to tired to try and do it again. xp * EDIT * I' so tired that I forgot to change all the "K's" into "n's" so any K's you see in there is supposed to be an n. Wow, I should probably sleep.

I was never good in math.
What kind of problem is this?
My brain hurts just looking at that.
XP
I'll give it a try...but tommorow..
I'm too tierd right now..

just the attempt to convert the power series function to a more "simplified" version by using mathematical induction.

That's ok, I tend to forget some stuff too. Like my Ecology unit in Honors Bio. * shivers * I hate Ecology to a degree, or at least the study of it...definantley not my place in the world of science. Yeah, like said in my intro profile I'm teaching my self some Calc, and pre-calc stuff. I think I'm doing pretty well so far, but this problem just had me stumped today.

Im not sure if I worded this correctly, I read this in one of Mr. Hawking's books long ago, but why is the sum of two event horizons greater than the "true" sum...i.e. 2+2=5? thanks everybody!

Well this depends, what part of the event horizon, or rather, what characteristic? The Required Escape Velocity? The output of Hawking radiation?

No I think its a matter of dimensions: the total surface area. Im checking for the book now to clarify my question.

Can anyone tell me how to integrate? And by that I mean integral Calculus. There's not much information that I've found about it, but, I'm pretty sure it is essentialy doing the opposite of taking a derivative. And finding the Area of a function by using infintesimaly(spelling?) small Rectangles...

why is there an explosion when very hot water comes in contact with metal? I saw it on mythbusters
