=Elodea, without salt:= //__interesting facts-__// -Elodea is a genus of aquatic plants often called the water weeds. //Elodea// is native to Native America and is also widely used as aquarium vegetation.

-it provides a good habitat for many aquatic invertebrates and cover for young fish and amphibians.

flat =Hydra= __interesting facts__ Hydra- is one of the simplest forms of many-celled animals. Hydras are related to the jellyfish, sea anemones, and corals. It is usually found sticking to a submerged leaf or stick. Its body is a simple, threadlike tube 1/8 to 3/4 of an inch (3 to 19 mm) long. One end is closed; the other consists of a mouth surrounded by five to eight tentacles. These tentacles have nettling (poison) cells with which the hydra paralyzes its prey of larval insects and tiny crustaceans. The hydra's activities are regulated by sensitive nerve cells, for the animal has no brain or vision. A hydra has two cell walls with a thin layer of jelly in between. It has a mouth, tentacles, and lots of stingers. Hydras live in freshwater ponds.

=Elodea, with salt:= //__interesting facts:__//

-The salt can not get into the cell membrane, so the water goes out. -The area outside of the leaf has high concentration of salt and the inside of the leaf has a low concentration of salt. -The salt water most likely would kill the cells of the plant.

 * Cube Size || Area of Cube || Volume of cube || Surface area to volume ratio || Distance of Diffusion || Rate of Diffusion ||
 * 1x1x1 ||  1  ||  1  ||  6/1  ||  1/2cm  ||  .5cm  ||
 * 2x2x2 ||  4  ||  8  ||  3/1  ||  1/2cm  ||  .5cm  ||
 * 3x3x3 ||  9  ||  27  ||  2/1  ||  1/2cm  ||  .5cm  ||









The volume of the cubes is different in each one because they are different sizes. The surface area to volume ration is different because the sizes are different. To find the volume, surface area volume ration, distance of diffusion, and rate of diffusion we multiplied. If the cell size was any different than the efficiency would be different.

=Biomolecules Food Results:= No one else had the same foods as us, but if any one would have put more of an amount of onion or black beans they might have gotten a different color than us.

There are 14.9 g and 5% carbohydrates in a raw onion the dietary fiber is 2.7 g and 11%. Starch is 0.0 g and sugars are 6.8 g. The proteins is a raw onion are 1.8 g and 4%. Antioxidative efficiency to inhibit lipid oxidation of ascorbic acid is (0.05%) and 50% ethanol extract of onion peel (0.05, 0.1, and 0.2%) in raw ground pork was investigated during chilled storage (16 days). There is 116 g in carbohydrates in a black bean. There is 39 g proteins and 1.7 g lipids in the black bean.

=Biomolecules in Food Lab:= What was a surprised us was the color changes, they went from light blue to orange or black. Most of them weren't the same, but some changed completely. The negative and positives were different looking than what we thought, and the color changes were unexpected for the negatives and positives.
 * || Benedict || Biuret || Iodine || Sudan 4 ||
 * Onion || Negative || Positive || Stayed Orange || Negative ||
 * Black Beans || Positive || Positive || Brown to Black || Negative ||

Some people in other groups had different color changes because they had different foods than us, no one had onions or black beans.
