PLEASE HELP! match each of the following characteristics with the correct macromolecule. you may use the macromolecule more than once.

A) subunits are simple sugars
B) has a 1:2:1 ratio is C, H,&O
C) functions as structure of hair&nails
D) elements present are C, H,O, N,&P
E)hemoglobin, insulin, and antibodies are examples
F) functions include energy storage and insulation
G)is held together by peptide bonds
H) subunits are 1 glycerol & 3 fatty acids

1. carbohydrates
2. lipids
3.proteins
4. nucleic acids

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
