An inoculating loop was used to transfer culture to the agar surface. However, the increased use of FFAs as fuel at the expense of glucose leads to an increased energy cost, a decrease in cardiac efficiency and an increased propensity for impaired LV function.

Failure to develop an interesting hypothesis may lead a scientist to re-define the subject under consideration. This is similar to a dependent variable, which is a condition or piece of data in an experiment that is controlled or influenced by an outside factor, most often the independent variable.

The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. A response variable is the observed variable, or variable in question.
