In the United States, federal grants are economic aid issued by the United States government out of the general federal revenue. A federal grant is an award of financial assistance from a federal agency to a recipient to carry out a public purpose of support or stimulation authorized by a law of the United States. Grants are federal assistance to individuals, benefits or entitlements. A grant is not used to acquire property or services for the federal government's direct benefit.
Cnidarians are said to be the simplest organisms at the tissue grade of organization. Their cells are organized into true tissues. Cnidarians are essentially bags made of two cell layers. The outer layer, or epidermis, contains the cnidocysts, the stinging cells that are characteristic of the phylum.nidarians are said to be the simplest organisms at the tissue grade of organization.

Cnidarians are classified into four main groups: non-moving (sessile) Anthozoa (sea anemones, corals, sea pens); Cubozoa (box jellies);swimming Scyphozoa (jellyfish); and Hydrozoa, a broad group that includes all the freshwater cnidarians as well as many marine forms. There are about 10, 000 species of Cnidarians.here are two major body forms among the Cnidaria-the polyp and the medusa. Sea anemones and corals have the polyp form, while jellyfish are typical medusae. When you look at them, you can see that these body forms are the same except that one is upside down.
