It is possible to find a crossbreed between a lion and a tiger, they are called Ligers or Tigons. I bullsh*t thee not - http://www.lairweb.org.nz/tiger/ligers.html

If the same were to happen with cats and dogs, would they be called dats or cogs? And would the babies be called cuppies or dittens (awww how cute!)

Would you feed them tins of cuppy cog or ditten dat (as opposed to kitty kat for cats)?

1.The units for acceleration are m2/s2.
2.Acceleration is a change in speed over time.
3.The slope of a speed-time graph gives the velocity.
4.A positive slope on a distance-time graph means that the object is accelerating.

from your cellphones to your television to your satellite, they all have 1 thing in common that is they run on the spectrum band but in different frequencies...

so i want to know which is the most dangerous that can cause radiation?recently there is a article post on yahoo says that cellphones are safe....

can any one explain what is the cause of radiation from the frequency?example like higher frequency means more dangerous since satellite is using the higher band and is much stronger, so my final question is will any of the frequency in the spectrum band harm us? which of them would harm us more?

I understand how mutation happens, what I don't understand is how it's propagated to the next generation. Let's say I have a gamma particle that hits a base pair in one of the genes in a skin cell. The cell mechanics repair the gene with a mistake (a mutation). How does that cell mutation get passed to my offspring? Wouldn't the mutation have to happen in the fertilized egg, before it splits, for it to be passed to my offspring?
