|---|---|
| Homeostasis | a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group |
| Excretion | metabolic waste products (such as urea and carbon dioxide) that are eliminated from the body |
| synthesis | the composition or combination of parts or elements so as to form a whole |
| egestion | the act or process of discharging undigested or waste material from a cell or organism |
| metabolism | the sum of the processes in the buildup and destruction of protoplasm |
| organism | a complex structure of interdependent and subordinate elements whose relations and properties are largely determined by their function in the whole |
| heterotrophic | requiring complex organic compounds of nitrogen and carbon (such as that obtained from plant or animal matter) for metabolic synthesis |
| Eukaryote(s) | any of a domain (Eukarya) or a higher taxonomic group (Eukaryota) above the kingdom that includes organisms composed of one or more cells containing visibly evident nuclei and organelles |
| Unicellular | having or consisting of a single cell |
| Taxonomy | the study of the general principles of scientific classification |
| Chordate(s) | any of a phylum (Chordata) of animals having at least at some stage of development a notochord, dorsally situated central nervous system, and gill slits and including the vertebrates, lancelets, and tunicates |
| Multicellular | having, made up of, or involving more than one and usually many cells especially of living matter |
| prokaryote(s) | any of the typically unicellular microorganisms that lack a distinct nucleus and membrane-bound organelles and that are classified as a kingdom (Prokaryotae synonym Monera) or into two domains (Bacteria and Archaea) |
| Genus | a class, kind, or group marked by common characteristics or by one common characteristic |
| Binomial nomenclature | a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself |
| Autotrophic | requiring only carbon dioxide or carbonates as a source of carbon and a simple inorganic nitrogen compound for metabolic synthesis of organic molecules (such as glucose) |
| regulation | involving or reproducing by reproductive processes (such as cell division, spore formation, fission or budding. |
| kingdom | a politically organized community or major territorial unit having a monarchical form of government headed by a king or queen |
| respiration | the movement of air or dissolved gases into and out of the lungs |
| asexual | involving or reproducing by reproductive processes (such as cell division, spore formation, fission or budding. |
