Question

question 18 (1 point) 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:

1. this group also recorded a dependent variable, which is represented by

the type of solution the egg is placed in
the change in mass of the eggs
the amount of time they were in the solution
the ending mass of the eggs

Explanation:

Step1: Recall the concept of dependent variable

In an experiment, the dependent variable is the one that is measured and is affected by the independent variable.

Step2: Analyze the experiment

The students are testing how different water solutions (independent variable) affect water absorption by an egg. The mass of the eggs is measured (the thing that changes based on the solution type), so the change in mass of the eggs is the dependent variable.

Answer:

b. the change in mass of the eggs
