In at least some form, all organisms are capable of response to stimuli, reproduction, growth and development, and maintenance of homoeostasis as a stable whole. An organism may either be unicellular (single-celled) or be composed of, as in humans, many trillions of cells grouped into specialized tissues and organs. The term multicellular (many-celled) describes any organism made up of more than one cell. The term "organism" (Greek ὀργανισμός - organismos, from Ancient Greek ὄργανον - organon "organ, instrument, tool") first appeared in the English language in 1701 and took on its current definition by 1834 (Oxford English Dictionary). Scientific classification in biology considers organisms synonymous with life on Earth. Based on cell type, organisms may be divided into the prokaryotic and eukaryotic groups. The prokaryotes represent two separate domains, the Bacteria and Archaea. Eukaryotic organisms, with a membrane-bounded cell nucleus, also contain organelles, namely mitochondria and (in plants) plastids, generally considered to be derived from endosymbiotic bacteria. Fungi, animals and plants are examples of species that are eukaryotes. More recently a clade, Neomura, has been proposed, which groups together the Archaea and Eukarya. Neomura is thought to have evolved from Bacteria, more specifically from Actinobacteria. From Wikipedia under the
GNU Free Documentation License What happens if an organism's density is greater than that of the surrounding seawater? Q. Marine organisms live surrounded by seawater of varying density. If an organism is less dense than the surrounding seawater, what might happen to that organism? Conversely, if an organism's density is greater than that of the surrounding seawater, what will happen to the organism? Asked by JK - Sun Nov 22 15:44:16 2009 - - 1 Answers - 0 Comments A. If it's density is greater than that of the water, it will sink... if it's less, it will float. Answered by chewy - Sun Nov 22 15:48:13 2009 Why is it unwise to try to relate an organism s complexity with its size or number of cells? Q. A) A very large organism may be composed of very few cells or very few cell types. B) A single-celled organism, such as a bacterium or a protist, still has to conduct all the complex life functions of a large multicellular organism. C) A complex organism can have a very small and simple genome. D) A simple organism can have a much larger genome. E) A single-celled organism that is also eukaryotic, such as a yeast, still reproduces mitotically. Asked by kristen - Sat Feb 27 19:59:13 2010 - - 1 Answers - 0 Comments A. A) A very large organism may be composed of very few cells or very few cell types. One of the world's largest organisms is a mushroom, or more specifically, the great fungal mass that produces all the mushroom caps, the reproductive organ, over a large area.

Q. I want to what do drugs do in the organism, and how? And which are the chemical reactions? Asked by pyro088 - Tue Apr 25 17:26:04 2006 - - 2 Answers - 0 Comments A. Every drug reacts differently and there are many chemical reactions. The most common method a drug uses though is to inhibit an enzyme that is causing the anomaly. It does this by binding to a "pocket" in the enzyme, most typically by ionic interactions. These are either in the form of hydrogen bonding, pi-pi stacking etc. These drugs are VERY specific and out of the thousands of different enzymes in your body they will target the right one. Most commonly due to the new ionic interactions it causes the enzyme to change shape and deform very slightly, which means it cannot combine with another enzyme to promote the disease, or bind specifically to another molecule in your body which would otherwise promote the disease.
