No helium needed to fill balloons for parties.....just vinegar and baking soda! I NEED TO REMEMBER THIS! this is important since helium is not a renewable source and is in such short supply. NEED THIS SOON! @Ashley Wallace, @Kayla Smieshek we need this for the balloons!
Chimera cat is one individual organism, but genetically its own fraternal twin. A chimera is typically formed from four parent cells (either two fertilized eggs, or two early embryos that have fused together). When the organism forms, the cells that had already begun to develop in the separate embryos keep their original phenotypes and appearances. This means that the resulting animal is a mixture of tissues and can look like this gorgeous (but bizarre) kitty.
