I really need the answer to both of these. If you answer first I’ll give Brainliest

1) carbohydrates

2)protein or nucleic acid

Explanation:

1)carbohydrates(CHO)are made of carbon, hydrogen, and oxygen

2)it's either protein or nucleic acid I'm not sure which one though sorry. Protein contains all 4 of those elements but contains sulphur, and nucleic acid also contains those elements with phosphorus.

1). Carbohydrates

2). Protein
