Edible seaweed soaps, and lotions. Common edible seaweeds include: Edible seaweed Edible seaweed, or sea vegetables, are algae that can be eaten and used in the preparation of food. They typically contain high amounts of fiber. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of polysaccharides such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other
Degree of an algebraic variety Degree of an algebraic variety In mathematics, the degree of an affine or projective variety of dimension is the number of intersection points of the variety with hyperplanes in general position (for an algebraic set, the intersection points must be counted with their intersection multiplicity) The degree is not an intrinsic property of the variety, as it depends on a specific embedding of the variety in an affine or projective space. The degree of an hypersurface is equal to the total degree of its defining equation. A generalization of Bézout's theorem asserts that, if an intersection of projective hypersurfaces has
