Scientists have all these complex ways of organizing living things. They look at your physical traits, how you develop as a fetus, or in an egg. They look to see if you are a plant.
Nitric oxide (.NO), a free radical species produced by several mammalian cell types, plays a role in regulation of vascular, neurological and immunological signal transduction and function. The role of .
species: A single, distinct class of living creature with features that distinguish it from others.
temperament: A person's way of responding to the world. Examples of temperament include shy, bold, risk taking, and cautious.
species pl. species
[L. kind, sort]
A particular kind of organism; members possess similar anatomical characteristics and have the ability to interbreed.
species diversity ...
species One or more populations of interbreeding or potentially interbreeding organisms that are reproductively isolated in nature from all other organisms.
Species: A group of individuals similar in structure and capable of interbreeding and producing fertile offspring. They are different in structure from other such groups and do not interbreed with them.
species variant In TAIR species variants include natural variants of Arabidopsis thaliana collected from a variety of sources (ecotypes) as well as related Genera and species of Arabidopsis.
Species Abundance: The total number of individual of a species within a given area or community. Compare species richness.
Species. A classification of related organisms that can freely interbreed.
Spore. A form taken by certain microbes that enables them to exist in a dormant stage. It is an asexual reproductive cell. See Asexual reproduction, Dormant.
species - a group of individuals similar in morphology, capable of interbreeding and producing fertile offspring. They are morphologically different from other groups and usually do not interbreed with them.
Subspecies: a geographically defined aggregate of local populations which differ phenotypically from other such subdivisions of a species in other geographic areas.
Extinct Species in Cladograms - Cladistics makes no distinction between extinct and non-extinct species,[7] and it is appropriate to include extinct species in the group of organisms being analyzed.
Species with population sizes that number in the hundreds to a few thousand, while not at risk for extinction due to demographic stochasticity, still face other risks.
Species
A group of organisms belong to the same biological species, if they are capable of interbreeding to produce fertile offspring.
Species are groupings of individuals which can interbreed. The formation of new species involves isolation and reunion.
species under consideration for listing as endangered or threatened but for which conclusive data on biological vulnerability are not currently available to support listing. Also known as Category 2 species.

Linneus also developed the concept of binomial nomenclature, whereby scientists speaking and writing different languages could communicate clearly.
Species richness. The number of species in an area or biological collection
Sporophyte. Diploid stage in the life cycle of a plant ...
species recovery plan A plan for restoration of an endangered species through protection, habitat management, captive breeding, disease control, or other techniques that increase populations and encourage survival.
A species of animal which possesses an amnion. This term is most often used in the plural (amniotes) to refer to reptiles, birds, and mammals collectively.
- A species of cereal grain. Used for food, and as fodder for animals, especially poultry and horses.
Olefinic ...
In many species of microorganisms individuals can be divided into two types. Mating can take place only between individuals of opposite mating types due to the interaction of cell surface components.
Apes: Species belonging to the Family Pongidae of the Order Primates: Gibbon (genus Hylobates), Orangutan (genus Pongo), Chimpanzee (genus Pan), and Gorilla (genus Gorilla). They have no tails.
A bacteria species that normally colonize corn roots have been given a gene that enables it to produce an insect-killing toxin (pesticide).
a transient species that cannot be measured in body fluids.

Allopatric Species species which occupy areas separated by space or time‚ therefore cannot come into contact with each other

There are more species of animals, then in all the other kingdoms combined. From worms, to blue whales, to bald eagles, animals have evolved to fit a wide variety of niches.
In most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route.
Reactive oxygen species One of several types of small molecules containing oxygen with an unstable number of electrons. Reactive oxygen species can damage many kinds of biological molecules.
The evolution of new species or sub- species to fill unoccupied ecological niches. Aerobe. A microorganism that grows in the presence of oxygen. See Anaerobe. Agarose gel electrophoresis.
Genetic linkage map -- a chromosome map showing the relative positions of the known genes on the chromosomes of a given species.
Louis puts it in his introduction to a modern reprint of Darwin's work: "The Origin of Species has special claims on our attention.
family, subfamily, subspecies.
Change of rank When a name is moved from one level of the classification system to another, e.g., when De Lotto (1955) moved Ceroplastes destructor brevicauda from the subspecies to the species rank C.
In addition to ERCC2, analysis revealed the presence of two previously undescribed genes in all three species. One of these genes is a new member of the kinesin motor protein family.
TransformationUsually refers to passive uptake of DNA by cells, although in nature some bacterial species have a specific active uptake system.
An organism that is different from other organisms of the same species due to genetic differences.
It was pointed out on page 37 that the number of chromosomes found in the nucleus is constant for all the cells in an animal of any given species, and that in man the number is probably twenty-four.
The evolutionary history of a species-which tells the characteristics of the various species from which it descended-together with its genealogical relationship to every other species is called its phylogeny.
Homologies Similarities in DNA or protein sequences between individuals of the same species or among different species.
Homologous chromosomes A pair of chromosomes containing the same linear gene sequences, each derived from one parent.
Evolution, as Darwin described it in "The Origin of Species" in 1859, had several components; three to be exact.
Evolutionary Footprinting: One can infer which portions of a gene are important by comparing the sequence of that gene with its cognates from other species.
The molar extinction coefficient (e) of a species is defined by the equation A = ebc, where A is the absorbance of the solution, b is the path length, and c is the concentration of the species.
Water is the basis of life, it supports life, and countless species live in it for all or part of their lives. Freshwater biomes supply us with our drinking water and water for crop irrigation.
A group of organisms of the same species relatively isolated from other groups of the same species. See deme.
