Question

leah, larenda, and gabi decide to test what factors influence water absorption by an egg. they remove the shell from 3 eggs by dissolving them in vinegar. they create three different water solutions. one is pure, 100% distilled water, a second is 50% water/50% corn syrup, and the third is 100% corn syrup. the mass of each egg is measured before they are put into a single solution for 24 hours. the mass of the eggs is then measured, and the data recorded below: this group also recorded a dependent variable, which is represented by type of solution starting mass ending mass change in mass distilled water 65.1 g 77.8 g 12.7 g 50/50 mixture 62.0 g 52.2 g -9.8 g 100% corn syrup 66.7 g 48.9 g -17.8 g a. change in the mass of the eggs b. the ending mass of the eggs c. the amount of time they were in the solution d. the type of solution the egg is place in

Explanation:

In an experiment, the dependent variable is what is being measured and is affected by the independent variable. Here, the researchers are measuring how the mass of the eggs changes based on the type of solution (independent variable). The amount of time is a controlled variable, and the type of solution is the independent variable. The ending mass is part of the data used to calculate the change in mass. So the change in mass of the eggs is what depends on the type of solution, making it the dependent variable.

Answer:

A. change in the mass of the eggs
