Question

Paisley wants to prepare a graph of the rate of growth of a lentil seedling. Which factors would be the independent and dependent variables?

A.The height of the lentil seedling would be an independent variable and the length of the leaves the dependent variable.
B.The height of the lentil seedling would be an independent variable and the time passed would be the dependent variable.
C.The time passed would be an independent variable and the height of the lentil seedling would be the dependent variable.

Answer 1

The answer is C. A dependent variable is one that is influenced by changes in treatments in the experiment. It is usually the variable that is being tested. The independent variable is the variable that is controlled/manipulated and used to influence the dependent variable. In this case, time is the independent variable while the height of the lentil plant is the dependent variable because time influences the length of the plant.

Answer 2

"The time passed would be an independent variable and the height of the lentil seedling would be the dependent variable" are the factors among the choices given that would be the independent and dependent variables. The correct option among all the options that are given in the question is the third option or option "C".
