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.
Ad. Demersal or benthic habitats are found on the bottom of the oceans. They are divided into the shallower coastal benthic and the deep ocean benthic habitats found beyond the continental shelf. Coral reefs are a benthic habitat in shallow, warm waters where an abundance of light penetrates.ere, no light penetrates and plants are not found. Organisms living in this ocean habitat are primarily detritus eaters, subsisting on the organic matter that floats to the bottom of the sea. Little studied due to the difficulties involved, this deep area is believed to be rich in biodiversity.
