Students used gummy bears to represent cells in the gummy bear osmosis lab. After obtaining an initial mass for each gummy bear,
the gummies were soaked for 24 hours in different solutions and then dried and massed. The solutions included: distilled water, tap water, 20% sugar solution, and 40% salt solution. After 24 hours, the percent change of each gummy bear was calculated and is shown below: Distilled Water: +320%
Tap Water: +200%
40% Salt Solution: -60%
20% Sugar Solution: +85%
Based on the data, which gummy bear was in the salt solution and what was the tonicity of that solution?
A) A; hypotonic
B) D; hypotonic
Eliminate
C) B; hypertonic
D) C; hypertonic
I think the answer would be white blood cells because the white blood cells are trying to fight the bacteria off. That’s what I think. Hope this helped
