A．Until about thirty years ago，astronomers thought that it was composed almost entirely of this "baryonic matter （重子物質(zhì)）"，ordinary atoms （原子）．Over the past few decades，however，there has been increasing evidence that there is something we can't see，perhaps some new form of matter．

B．They are composed primarily of chemicals called surfactants （表面活性劑） that have the special ability to surround oily materials on surfaces and allow them to be rinsed away while washing the hair by water．

C．They are made out of wax （蠟） and contain fragrances，minor additives，colorants and come in a variety of shapes and size．

D．It is a combination of both living and nonliving materials．One part of it is broken down rock．Another is organic matter made up of decaying （腐爛的） plants and animals．Water and air are also a part of it．

E．Some of them，such as polystyrene，are composed of monomers that contain only carbon and hydrogen （氫）．All organic plastics include a long backbone of carbon．

F．Basically，they're big exploding balls of gas，mostly hydrogen and helium，and the nearest sun is so hot that a lot of hydrogen is constantly reacting in the stars，like hydrogen bombs．

G．It depends upon the kind．Most of them are made from collagen/gelatin （膠原蛋白），which comes from the skin，bones and hooves of horses，pigs and cows．
