The answer is <span>B. The type of fertilizer.</span>
<span>An independent variable is variable that is not affected in the
experiment. It is what experimenter controls. On the other side, a dependent
variable is called dependent because it depends on the independent variables.
It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of

<span>The appropriate answer is A. the hemisphere is is tilted toward the sun and the sun reaches its highest point in the sky. This usually occurs on June 20 or 21. At this time the northern hemisphere experiences its longest day. Summer in the nothern hemisphere means that the earth is tilted towards the sun and receives sun rays that are more direct. </span>
In order to conduct a research you should have an dependent variable, independent variable and the control variable. so in order to study phototropism, then you should need sun light and the growth of the plant and you must have a control that why you need a dark room.
