However, as so many of the records are not certainly based on newborn snakes, these data must be taken tentatively ; ;

However, if these procedures are applied more often, conditioned emotional responses are temporarily abolished.

However, it cannot be presumed, informal though the structure of the population seems, that there are not well-defined roles within the system.

However, the differences in procedure are fundamental.

However, the regionally differentiated results, which appear below in tables, are interesting evidence of the problems of developing self-government under even the most favorable circumstances.

However, if Federal funds are used, it would be entirely appropriate to train workers for jobs which could be obtained elsewhere as well as for jobs in the area of chronic unemployment.

However, it is not known to either the union or the public precisely how much of a cost increase is caused by a given change in the basic wage rate, although the companies are presumed to have reliable estimates of this magnitude.

However, there are relatively few such political constituencies, and, as has been pointed out, there is seldom a clear-cut distinction between the educational interests of one social class and those of another.

However, modesty and triviality are different qualities.

`` However, evidence that the Axis powers are making significant preparations indicative of such an intention is being reported with increasing frequency from a variety of sources.

However, because organisms can be carriers of genes for albinism without exhibiting any traits, albinistic offspring can be produced by two non-albinistic parents.

However, it was the identification of vitamins A, C, and E as antioxidants that revolutionized the field and led to the realization of the importance of antioxidants in the biochemistry of living organisms.

However, together they address phenomena related to living organisms ( biological phenomena ) over a wide range of scales, from biophysics to ecology.

However, in the 1990s it rapidly became the dominant set of methods of phylogenetics in evolutionary biology, because computers made it possible to process large quantities of data about organisms and their characteristics.

However, ocean acidification by invading anthropogenic CO < sub > 2 </ sub > may affect the biological pump by negatively impacting calcifying organisms such as coccolithophores, foraminiferans and pteropods.

However, if neither of these organisms is isolated, it is necessary to send stool specimens to a reference laboratory.

However, the term disorder is also used in many other areas of medicine, primarily to identify physical disorders that are not caused by infectious organisms, such as metabolic disorders.

However, more specifically, the relationship was endosymbiotic, meaning that one of the organisms ( the bacteria ) lived within the other ( the eukaryotic cells ).

However, carbon dioxide has an advantage in this respect as it kills organisms through hypercarbia and depending on concentration hypoxia and, requiring concentrations of above 35 %, or so.

However, while this simple correspondence between an allele and a trait works in some cases, most traits are more complex and are controlled by multiple interacting genes within and among organisms.

However, before this drug is used in the clinic, it must progress through a series of in vivo trials to determine if it is safe and effective in intact organisms ( typically small animals, primates and humans in succession ).

However, pathogenic microbes are harmful, since they invade and grow within other organisms, causing diseases that kill humans, other animals and plants.

However, the earliest known idea to indicate the possibility of diseases spreading by yet unseen organisms was that of the Roman scholar Marcus Terentius Varro in a 1st century BC book titled On Agriculture in which he warns against locating a homestead near swamps:

However, other diseases such as influenza, yellow fever or AIDS are caused by pathogenic viruses, which are not usually classified as living organisms and are not, therefore, microorganisms by the strict definition.

However some microorganisms are pathogenic and can post health risk to other organisms.

However, many organisms have more than two sets of homologous chromosomes and are called polyploid.

However, not all organisms that use light as a source of energy carry out photosynthesis, since photoheterotrophs use organic compounds, rather than carbon dioxide, as a source of carbon.

However, not all PID is caused solely by STIs ; organisms that are considered normal vaginal flora can be involved, and individual cases of PID can be due to either a single organism or a co-infection of many different species.

However, like caesium, rubidium ions are handled by living organisms in a manner similar to potassium ions, being actively taken up by plants and by animal cells.

However, taxonomy, and in particular alpha taxonomy, is more specifically the identification, description, and naming ( i. e. nomenclature ) of organisms, while " classification " is focused on placing organisms within hierarchical groups that show their relationships to other organisms.

However, systematics alone deals specifically with relationships through time, and can be synonymous with phylogenetics, broadly dealing with the inferred hierarchy of organisms.

However, organisms and ecosystems, as far as it can be determined by the fossil record, do not appear to have undergone the significant change that would be expected by a mass extinction.
