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.
Habitat and Distribution Starfish or sea stars are found in most of temperate and tropical oceans of the world.They are exclusively marine and are bottom dwellers. Sea stars are found in a variety of habitats from the intertidal zone down to the bottom of deep seas but they are mainly found in shallow marine environments.They are found in sand, amongst rubble and on coral reefs and rocky bottoms below low tide as well as in estuaries and under the sand on beaches.ea stars are found in a variety of habitats from the intertidal zone down to the bottom of deep seas but they are mainly found in shallow marine environments.
