Question
How are cells affected by the movement of water? they expand Hypothesis
(What do you think will happen to the egg after the three days? Be sure to give a reason for your hypothesis.) i think the shell of the egg will dissolve and the egg will expand in the liquid.

require a longer explanation in paragraph form.
1. the egg got bigger each day by a little bit. at least 1cm.
2.
my hypothesis was somewhat correct. i said the egg shell would dissolve and in the liquid and it did. and it also expanded. but i had know idea that it would have changed the structure of it. 2. the egg was increasing in the size. so it would passive transport.passive transport is the movement of materials across the cell membrane without the use of energy by the cell. it was expanding through time. by the end of the first day it the egg of the shell was already off. and by the last day it was hard enough for us to hold. so when the egg is in the acid they both make a chemical reaction and carbon dioxide is released. it it takes about a day till all of the carbon is out of the egg. then it becomes soft. 4. the process of osmosis, water moves through the permeable membrane of the lettuce cells. the lettuce then becomes crisp.Osmosis is the process in which water moves from a higher concentration to a lower concentration. A membrane is not needed to actually do osmosis but osmosis can occur in the presence of a membrane. but the lettuce in the water becomes firm because of the cell membrane structure. 5. i think if you put syrup on an egg it will do nothing to it. i think since the egg is rubery
it would just slide off. or that it would stick and make it a little bigger. but i think that putting syrup on wouldn't make that big of a difference.
