mistake so much of it for food has never been fully explored” (Parker). Some studies say because of the smell of the algae in the ocean. That very well could be true. As algae breaks down naturally in the Ocean they emit a stinky sulfur odor known as dimethyl sulfide. ( National Geographic). Most sea turtles mistake ziplock bags for jellyfish. Bigger fish mistake tiny pieces of debris as plankton. More than two hundred marine animal species have been documented consuming plastic. Seabird’s are one specific

The nervous system is the most important system in the body. It transmits impulses to and from the brain. Disruption of the nerve cells and fibers that transmit the messages severely impairs the body’s ability to carry out complex function. Once a disruption occurs‚ one may never recover and neurological function will steadily degrade. Multiple Sclerosis is a disease that disrupts this network. Multiple Sclerosis (MS) is the most common disabling neurological disease in young adults between 20 and

Phytoplankton From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Diatoms are one of the most common types of phytoplankton. Phytoplankton are the autotrophic component of the plankton community. The name comes from the Greek words φυτόν (phyton)‚ meaning "plant"‚ and πλαγκτός (planktos)‚ meaning "wanderer" or "drifter".[1] Most phytoplankton are too small to be individually seen with the unaided eye. However‚ when present in high enough numbers‚ they may appear as a green discoloration

N-dimethyltyramine‚ is an alkaloid of the phenethylamine class that occurs naturally in a variety of plants‚ taking its name from one of the commonest‚ barley (Hordeum species). Chemically‚ hordenine is the N-methyl derivative of N-methyltyramine‚ and the N‚N-dimethyl derivative of the well-known biogenic amine tyramine‚ from which it is biosynthetically derived and with which it shares some pharmacological properties (see below). Currently‚[1] hordenine is widely sold as an ingredient of nutritional supplements
