why do snails not like salt??(plz help: science project!!!)?

The salt causes chemical reactions to occur and the iodine chephapod in the snail dissolves and the snail dies

If I remember right, the crystalline structure of the salt breaks down, and the Na and Cl ions move freely in the water, dissolving into the water.\nSince the salt breaks down into free ions, that explains why salt water is such a good electrical conductor.

they probably have more salt/sodium in their skin then u do.it has to do with that.

Rock salt and table salt ar two different ionic compounds.  Roack salt, calcium chloride, contains 3 ions: one calcium and 2 chloride ions.  Table salt has only 2 ions: one sodium and one chloride.\nSo who cares?  Well, the more ions (rock salt!) that are added to the ice (to make ice cream), the lower the freezing point of the ice will be.  Rock salt (3 ions) make the ice colder than the table salt (2 ions).  This is the only way the fatty moleculse of the cream can freeze into ice cream.  With table salt the ice just isn't cold enough.  The size of the salt crystals is not relevant.

each of these are salts.  A high salt level is a deterant to microbial growth, basically all the water inside the microbial cell wants to rush out into the salt to equilibrize concentrations.  Basically that kills the cell.   There are some bacteria however that are halophiles (salt-loving) that can live in high salt concentrations, most of those however exist in nature in very harsh environments such as sea basins which have dried and left a large amount of salt in the surrounding soil

because the salt u use in the kitchen does not contain all the particals in the sea water like sodium sulphate magnesium sulphate etc because they are removed in the process  of making the salt and some times the salt it cut down from deep earth and they are also cleaned by removing the toxic particles and iodised which may alter the sea water salt from earth solt altho the main component of salt is Na Cl it has other particals such as iodine and k+ irons Fe ect...

LMAO!!!!! thats a funny question! have u seen how a snail eats? its so cute!! worm would probably be a bit too big for a snail to eat, and a worm would be too rough for snails to bite. snails have no teeth...they're cute! annnd yeah, they're vego's!

1. pearls are made because of an irritation to the oyster inside the shell. the irritation is then covered by the oyster w/ calcium carbonate & after many years it is now a pearl.  a diamond is made from carbon from decaying plants & animals buried in the ground for  millions of years then subjected to immense pressure of the earth to form a rock-hard diamond.\n\n2.  you mean sea water? sea water is too salty w/ at least 3.5% salinity making it undrinkable for humans.\n\n3. the fish dont 'see' using their eyes.  they use a variety of organs to find their way in the water.  when you look at a fish, they have a line running through the middle of the body up to the tail. it is a sensory organ used by the fish to ' see'.  others have acute sense of smell or taste like the sharks.  others have a rostral organ in their snout w/c acts like an electrical field receptor.\n\n4. maybe women because the current world record holder in the free diving catergory is a woman named streeter who can hold her breath for 6 min while diving to 525 feet.

Here's a piece of the answer:\n\nThe important thing to remember is that the snails MUST have a constant supply of calcium to keep the shell strong (the shell is, after all, the snail's home, and without it, he'd die!!).

what do you mean by "salt"? There are hundreds of thousands of salts~~~\n\nsodium chloride for what you normally eat.

1. Maybe they're not used to the snow or 2. I believe the salt can be harmful in some way and maybe they are more eco-friendly out there.

Salts love water because they are ionic, and can have polar interations with the polar water molecules. The salt will soak up water from the air, and eventualy will become hydrated salt.

ions are polar, so they don't mix with the non-polar lipid bilayer. there are protein channels for their transportation, and pumps and all that..

Ther are millions of species of land animals that don't drink water. Snails, frogs, earthworms and so on. These animals all absorb water directly thorugh their skins and through their food and and never drink.\n\nThere area also numerous mammals species that don't NEED to drink water but regularly do. Everything from kangaroo rats to house mice to koalas.\n\n\nSorry, the question doesn't have an answer.

2400mg Max! Its hard to do coz all process foods have salt.Dont add salt to anything and read labels carefully.Cheese pizza and hamburgers are loaded with salt!Forget fish and chips all together.Look at bread labels, cottage cheese,even yogurt and you will be surprised at the amount of salt they have! The AMA is trying to force the FDA to add a new label to foods.I hope they can do this coz it will be a great help.

No, there are some insects that do not require salt to live.

Because of osmotic pressure.\n\nThe water in the fish's body is full of impurities.  You know, fish parts.  Osmosis causes water to flow automatically to less "pure" concentrations.  So, a freshwater fish has no need to drink, the water is simply pumping into it's cells.  In fact, it has to work extra hard to get waste water out of it's system so it doesn't swell up and explode!\n\nSaltwater fish have the opposite problem.  The salt in the water turns the osmotic pressure around and the oceans are constantly pumping water out of saltwater fish.  They have to drink to make up for it.
