1. Observations: Provide possible explanations to the following:
Bubbles are coming out of the egg shell when soaked in vinegar
The egg soaked in distilled water got bigger.
The egg soaked in soda got bigger
The egg soaked in corn syrup shrunk.
The syrup turned watery.

2. Eggshell in Vinegar
Calcium carbonate( egg shell)+ acetic acid(vinegar,4%) Calcium hydrate+ Carbon Dioxide
CaCO3(s) +2 HC2H3O2(aq) Ca (C2H3O2)2 (aq)+H2O+CO2 (g)

The Plasma Membrane

Types of Transport Proteins
Channel proteins are embedded in the cell membrane & have a pore for materials to cross
Carrier proteins can change shape to move material from one side of the membrane to the other

Facilitated Diffusion
Some Carrier proteins do not extend through the membrane.
They bond and drag molecules through the lipid bilayer and release them on the opposite side.
