Draw two structures (one straight chain and one ring) of a carbohydrate with the chemical formula (ch2o6).

how would i do this? ?

The chemical formula CH2O6 is not a carbohydrate unless it was written this way:
(CH2O)6 which is now the chemical formula of glucose.
Glucose has a linear and a cyclic structure. I will attach the structures since it's difficult to describe the drawing. The first one is straight chain and the next one is the ring.

The offspring will be blood type aa, bb, ab and oo or i
