Scientific Method- Bio 1

This graph shows how temperature affects the volume of a new polymer gel that may be useful in sorting DNA fragments using gel electrophoresis.What can be inferred from the results of the graph?

• Temperature is directly proportional to the volume of a given mass.

• Temperature is inversely proportional to the volume of a given mass.

• Mass is destroyed as the temperature increases.

• The energy is lost as the volume increases.
