This prefix means "one" and is used to describe simple sugars.
Mono-
100
This property of lipids prevents them from mixing with water.
Insolubility
100
This is the building block monomer of proteins.
Amino acids
100
This is the abbreviation for deoxyribonucleic acid.

In an experiment, the setup that provides a basis of comparison is known as:
a control
200
This complex carbohydrate is used for food storage in plants.
Starch
200
A triglyceride is composed of glycerol and this many fatty acid molecules.
3
200
This element is found in proteins but not in carbohydrates or lipids.
Nitrogen
200
This is the building block of nucleic acids.
Nucleotides

"The height of bean plants depends on the amount of water they receive."
The amount of water they receive is the ___________.
The independent variable
300
These elements are found in all organic compounds.
Carbon and hydrogen
300
These 3 elements are found in lipids.
Carbon, hydrogen, oxygen
300
This is one function of protein in the body.
Repair body tissues, prevents infections and illness, hormones, enzymes

On the data table below, identify the dependent variable:
Number of pups
400
Which structure is showing a carbohydrate?
A
400
This type of fatty acid contains at least one carbon-carbon double bond.
Unsaturated
400
This prefix meaning "large" describes complex biological molecules.
Macro-
400
These 5 elements are found in nucleic acids.
Carbon, hydrogen, oxygen, nitrogen, and phosphate

The rat mass is the ____________ variable in this experiment.
Four groups of rats are first massed and then fed identical diets except for the amount of vitamin A they receive. Each group gets a different amount. After 3 weeks on the diet, the rats’ masses are measured again to see if there has been a decrease.
Dependent variable
500
This function of a carbohydrate is often confused with a function of protein.
Quick energy
500
Lipids function primarily for this type of energy storage in the body.
Long term energy
