Cell Structure and Function
A researcher was studying the properties of cell membranes. Two sea cucumber eggs, with identical mass (mass of each egg is equal to 6.5545 x 10-8 g) where placed in two different solutions and the eggs were weighed every two minutes. One egg was placed in a hypertonic seawater solution, while the second egg was placed in a hypertonic seawater solution which contained ethylene glycol.
There is a graph depicting that both eggs lose mass and then gains mass. However, the egg in the solution containing ethylene glycol gains mass faster.
1. Comment (describing detail why the results appear the way they do) on the experimental results in light of your understanding into biological exchange mechanisms.
