Question

you perform an experiment in which you take 16 pots of strawberry plants and give half of them 1 gram of ammonium nitrate (nh₄no₃) per liter of water and the other half receive only water. each group is then split in half again, and exposed to either eight or 16 hours of light each day. you monitor the height of the plants for four weeks. you observe that plants grown in ammonium nitrate and 16 hours of light grow taller than no ammonium nitrate and eight hours of light. which of the following are dependent variables in this experiment? options: amount of ammonium nitrate and light; amount of carbon dioxide; amount of water; height of the plants; height of the plants and amount of light

Explanation:

A dependent variable is the measured outcome of an experiment, affected by changes to independent variables. Here, the experiment manipulates ammonium nitrate amount and light duration (independent variables) to measure how they affect plant height, which is the monitored outcome. The other options are either independent variables or unmeasured factors not part of the experiment's monitored results.

Answer:

Height of the plants
