Answer: The type of molecule is nucleic acid.
Nucleic acids are formed by nucleotides and those nucleotides are composed by three components, in which one of them is a sugar. If the sugar is a deoxyribose, the polymer is DNA (deoxyribonucleic acid).
The answer is nucleic acid because DNA, the molecule that caries genetic information, is a nucleic acid.

Explanation:
Three types of investigation are used by scientists to solve a problem or answer a question. These questions are: comparative investigation, descriptive investigation and experimental investigation. Experimental investigations are conducted to test the relationship between two variables. In the test, one of the variable is manipulated (independent variable) while the other responds (dependent variable).
In this case involving questions asked for a science fair, HOW DIFFERENT TYPES OF GRASS AFFECT BALL ROLLS is most likely an experimental investigation because it is testing the effects of grass type (independent variable) on ball roll (dependent variable).
