Question

use the information and table to answer the following question. a group of students conducted an experiment using de - shelled eggs to model how water moves across a cellular membrane. each egg was placed in a different solution for 24 hours, and the mass of each egg was recorded before and after the treatment. their data is summarized in the table below. based on their data, which of their eggs was placed within a hypertonic solution? a egg 2 and egg 3 b egg 2 c egg 1 and egg 3 d egg 1

Explanation:

Step1: Recall osmosis concept

In a hypertonic solution, water moves out of the cell (or in this case the egg), causing the mass to decrease.

Step2: Analyze egg mass changes

Egg 1 has a change in mass of - 2.2g, Egg 2 has a change in mass of + 3.1g (increase, so not in hypertonic solution), Egg 3 has a change in mass of - 1.5g. Eggs 1 and 3 show a decrease in mass.

Answer:

C. Egg 1 and Egg 3
