Seedlings in a Jar Imagine you have a sealed jar containing five bean seeds, air, and a moist paper towel. Nothing can get in or out of the jar. The total mass of the jar and its contents is 500 grams. Imagine the same jar with its contents 12 days later. During that time the jar remained sealed. Nothing could get in or out of the jar. The seeds have germinated to form 6-centimeter seedlings. The total mass of the jar and its contents after the 12 days is recorded.

Select the statement that is the best comparison of the total mass of the jar and its contents before and after the seeds sprouted to form seedlings:

A The total mass of the original jar with seeds will be more than the total mass of the jar with the seedlings.
B The total mass of the original jar with seeds will be less than the total mass of the jar with the seedlings.
C There will be no change in the total mass of the jar with seedlings after 12 days.
