Alexis placed one egg in a solution of 95% corn syrup. she placed another egg in distilled water. both eggs were treated with vinegar so the shell was removed before placing the eggs in the test liquids. the egg in the solution of corn syrup lost 33% of its weight. the egg in the distilled water gained 39% in weight. alexis wrote this passage to explain her observations however some of the details are incorrect. press on the words in the passage that are incorrect.

Alex observations after the experiment, she wrote some incorrect  observation:  

These observations can be explained because of the movement of water in and out of the egg. The solution of corn syrup was hypotonic meaning that the concentration of water was higher inside the egg. Water therefore moved into the egg by active transport. The distilled water was hypertonic. Therefore, the concentration of water was lower inside the egg. Water thus moved outside the egg by osmosis. Once the concentrations reached equilibrium, the water molecules stopped moving across the membrane.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
