A functional group is a group of atoms that give characteristic properties to organic compounds.
A functional group is a certain group of atoms within a molecule. They are responsible for specific chemical reactions of that molecule.

Monosaccharides

Isomers have different physical and chemical properties.

Polysaccharides are formed by a dehydration synthesis reaction between monosaccharides. What does this mean?

TACA

GLYCOGEN

Adding sufficient heat would harm or kill a living thing.

NaOH and NaClAl(OH)3 and NaOHBa(NO3)2 and Al(OH)3Ba(OH)2 and Ba(NO3)2

Lemon juice is more acidic. Lemon juice has a pH of 2, which is very acidic. Sodium hydroxide is alkaline, with a pH of 14. However, I'd consider sodium hydroxide considerably more dangerous, as even a small splash can cause painful burning.

Baking soda. The others are acids.
