I see so many funny clips of baseball coaches covering bases with clay when they're mad. Its not going to stop the game or hurt the umpire. What's the deal?

What is the UNO card symbol thats an O with a diagonal slash? What are the rules that go along with it?

What exactly is the "baby hair" that some adults have? Does it have a scientific name? Why is this hair, that's around some of our hairlines, shorter and finer that the rest of the hair on our head. Can anyone explain it? Is there a scientific name for it?

Pics of celebs w/ baby hair. (Some natural, some wigs.)

The Geek Squad sold me something that blocks me from programs and sites I want to go to. I need a good anti virus/anti spyware/enamelwaree. Should I buy Ad-Aware Pro from LavaSoft? Should I donate to get protection from Spybot?

It seems like insects come out by the millions when it's sunny. I wouln't expect so see most of them on rainy days (besides earthworms surfacing and ants trying to get inside). But it seems like most insects are no where to be seen on cloudy, gloomy, or cool days. Why is that? I have a theory but maybe someone else can let me know the deal.

Twins either come from one egg (monozygotic/identical) or two eggs (dizygotic/fraternal). Some doctors and twin organizations are no longer using the term identical and fraternal because no two individuals are exactly alike. And sometimes during the early embryotic stages, genetic changes can cause monozygotic/"identical" twins to be very different.

There can be twins that come from the same egg but have opposite sexes for two different reasons:

1.) If the fertilized egg contains a Y chromosome (normal male chromosomes are 46,XY), genes on that Y chromosome ensure that the developing gonads are testicles. If there is no Y chromosome (as in a normal, 46, XX girl), the gonads become ovaries.But not all girls have normal female chromosomes (46, XX). A small number only

have one X chromosome (45,X) and they have some developmental problems. These children have Turner syndrome.

Now, suppose you have a 46, XY fertilized egg, but, early in cell divisions after fertilization, a cell loses its Y chromosome? Now you have two types of cells in the developing embryo—46, XY and 45, X. If the embryo splits to make twins, you can have a normal boy (46,XY) and a Turner syndrome girl (45, X). This has happened on several occasions and is well known to geneticists and researchers.

2.) Alternatively, the original fertilized egg could have one extra X chromosome (47, XXY). This condition is called Klinefelter’s syndrome. If there are losses of chromsomes (as described above), you could have one 47, XXY cell that loses an X to become 46,XY (normal boy) and another 47, XXY cell that loses the Y to become 46, XX (normal girl). If MZ twinning occurs also, you end up with a normal boy and a normal girl. These chromosome changes after fertilization are quite rare, but they have been fully investigated. They show that MZ twins are not always genetically “identical,” although most people wrongly assume that they are—yet another reason to stop calling MZ twins “identical.”

I keep hearing I do but didn't believe it so I did a comparison. What do you think?
