Answer:The ice was the Dependent Variable
Explanation: the outcome of tge experiment would only be determined based on the suroundings, such as the plastic, aluminem, and the paper, all of which effect the ice therefore making the ice the dependent variable
Variables are the factors or quantities that may remain fixed or get changed. The final mass of the ice at the end of the experiment is the dependent variable. Thus, option D is correct.
What is a dependent variable?
A dependent variable is defined to be a factor or value that relates to and depends on the results and outcomes of the independent variable. In an experimental design, they are the parameters that affect the result.
The dependent variable undergoes a change in its values based on the other factors and variables. It has been compared to the control or the standardized groups. They are also referred to as outcome or the response variables as they are conditional to changes.
Therefore, option D. the final mass of ice is a dependent variable as it is conditional to different materials.

Your question is incomplete, but most probably your full question was, A biology class wanted to study the effect of different materials on the melting rate of ice. They placed pieces of ice, each with a mass of 10g, onto trays. Group 1 was covered in plastic, group 2 was covered in paper, group 3 was covered in aluminum, and group 4 remained uncovered. Each piece of ice was allowed to melt for 15 minutes. The final mass of the ice, minus the melted water, was recorded at the end of the experiment. What is the dependent variable in this experiment?
A)The type of covering material
B)The amount of melting time
C)The starting mass of the ice
D)The final mass of the ice
