Answer 1

A sugar or one of its dimers or polymers

Question 2

Lipids

Answer 2

Any of a group of large biological molecules. Phospholipids, fats, steroids.

Question 3

Answer 6

A chain of monomers

Question 7

Monosaccharides

Answer 7

Monomer of carbohydrates

Question 8

Disaccharides

Answer 8

Two monosaccharides connected by a glycosidic linkage

Question 9

Question 10

Saturated Fats

Answer 10

Fats saturated with hydrogen
Ex: C5H10

Question 11

Unsaturated Fats

Answer 11

Fats unsaturated with hydrogen. Double bonds cause kinks that make it hard for these fats to freeze

Question 12

Phospholipids

Answer 12

A kind of lipid where a phosphate head takes the place of one of the three fatty acids on the glycerol. The main component of the semi-permeable membrane

Question 13

Steroids

Answer 13

A type of lipid where the carbon skeleton is composed of four fused rings and a multitude of functional groups
