A scientist wаnts tо study the effects оf а new Drug X оn cаncer cell growth. Equal numbers of cancerous liver cells are grown on ten plates in a lab. Drug X is added to five plates. Water is added to the other five plates. The ten plates of cancerous cells are incubated at 37 Celsius for two days. After two days the plates are removed from the incubator and the number of cells is counted on each plate. What is the dependent variable?
