What is the "control" in the Vinegar and Egg experiment? (Tonicity of the animal cell). The solutions used are 100% distilled water, 100% corn syrup, 10% corn syrup/90% distilled water and the control. I have no idea what the control is supposed to be. the information given in the lab makes no sense to me. Can anyone help me out with this?
Homework Answers
In the egg and vinegar experiment, control is egg in distilled water. (100%). The egg will not shrink or form bubbles when placed in water. The one with corn syrup is test samples.

The density of vinegar is 1.01 g/mL. How would this information
affect your experimental results.

If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase
If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase? i think it decreases but i'm not sure. and if a plant cell has a lower water potential than its surroundings and if pressure=0, is the cell hypertonic(in terms of solute concentration) or hypotonic to its environment? will the cell gain or lose water? any ideas...?http://en.wikipedia.org/wiki/Water_potentialanalysis queswhat is water potential?Osmosis Lab /27819 Name: ________________________________ Date: ___________...
