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?

(A) The type of soil, temperature, amount of rain and sunlight in the area
(B) Vitamin C levels
(C) Blueberries
(D) Raspberries

The correct answer is B) Vitamin C levels.

The dependent variable in this experiment is Vitamin C levels.

When we are talking about research, a dependant variable is the one that is being tested in the research. The scientific approach, in this case, is the amount of vitamin C in raspberries and blueberries. What researchers try to measure is the dependant variable that is vitamin C in each of those fruits.  

b) the inside picture would look at a very high temperature in a very low ph
