An identical balloon kept at the original temperature. Independent variable in an experiment is the variable that the experiment plans to change while the dependent variable is the variable whose value depends on the independent variable.
Rhythm Salsa resulted from the development of a muscle cell culture technique.
<h3>How to do cell culture?</h3>

With this information we can conclude that rhythm Salsa resulted from the development of a muscle cell culture technique.
