1) d, phospholipids.
2) missing any except thymine, because proteins are made from an RNA template, and RNA doesnt contain thymine...though RNA is made from DNA, and if you dont have thymine, you cant make DNA....hmmm
3) I would say a and c, because those are like the same thing, but i'm not sure.
4) a
5) d - carbs are defined as only containing C,H, and O, and fats too ( i think..hehe)
