Considering that the human starts off from 1 single cell, which then multiplies out , where does all that information on how the rest of the cells should be created come from . I presume it's in the DNA , a sort of a chemical compiler / assembler which tells the cell on how it should multiply. But even if it has information about all the different cells in the body , how does it know which ones to build next. I find it incredible and incomprehensible that a single cell can grow into an intelligent human being .

I recently went on holiday to Spain, and whilst there I was bitten about 25/30 times in a week. Since coming home i've spent days trying not to scratch the bites. So whilst my question is primarily why do they itch, I would also like to know if there is any way of stopping them itching? thanks.

My grand-nephew has a question for school that will get him extra credit.
How if a young man who has an 18 inch step far will he have to travel in miles if he takes one step forward and two steps back to reach 10 miles and 100 miles?
I have no idea how to figure this out. Can one of you fine people explain it so that I could explain it to him?
I don't have a printer either.
Thanks so much.

What is the difference for user in terms of coverage/reception in different frequency bands? i.e. does GSM 1800 have better coverage than GSM 900? Why does a lower frequency band show better penetration power? We studied that a baseband signal is modulated to have "higher" frequency to gain distance. Aren't these statements contradictory? Does GSM 1800 cover less area but with better voice quality? Please help!
