You have formulated a hypothesis: "Blueberries contain more vitamin C than raspberries." To test your hypothesis you measure vitamin C levels in 20 blueberries and 20 raspberries from bushes that were grown in the same area under the same environmental conditions (temperature, rain, sunlight). What is the dependent variable in this experiment

Vitamin C levels

Step-by-step explanation:

In order to identify which is the dependent variable in a experiment, it is useful think which is the variable being tested in the experiment. Whereas for the independent variable you need to check which is the variable that is usually controlled to test its effects on the dependent variable.

In this case you are measuring vitamina C levels (dependent variable) which you expect that depends on the fruit which you are testing (variable independent).

Note that the environmental conditions are factors which can affect also your dependent variable but you are not controlling that. They could be independent variables if you manipulate them.
