What is homocysteine? Homocysteine is an amino acid. Amino acids are the building blocks of proteins. When proteins break down, elevated levels of amino acids like homocysteine may be found in the bloodstream. Having elevated levels of homocysteine in the blood (hyperhomocysteinemia) is associated with atherosclerosis and blood clots.
The marine environment supplies many kinds of habitats that support marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean).A habitat is an ecological or environmental area inhabited by one or more living species.Marine habitats can be divided into coastal and open ocean habitats.oastal habitats are found in the area that extends from as far as the tide comes in on the shoreline out to the edge of the continental shelf. Most marine life is found in coastal habitats, even though the shelf area occupies only seven percent of the total ocean area.
Seaweed, which is a type of phytoplankton, is commonly found floating on the surface of the ocean. It is harvested by people for food and material for housing, baskets and ropes. Seagrasses are rooted marine plants that live on the ocean floor. These flowering plants provide habitat for small fish and other marine life. Types of seagrasses include shoal grass, manatee grass and turtle grass. Red algae live in warm tropical water, while coralline algae grow on rocks. The ocean also has an abundance of kelp beds that grow in cold temperate regions.
