These toxins and the organisms that produce them are sometimes referred to as select agents.

These are sites of exceptional preservation, where ' soft ' parts of organisms are preserved as well as their more resistant shells.

These hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans.

These are then taken up by organisms in the soil, react with mineral soil, or are transported beyond the confines of the ecosystem ( and are considered " lost " to it ).

These cells and the bacteria trapped inside them entered a symbiotic relationship, a close association between different types of organisms over an extended time.

These modern organisms with endosymbiotic relationships with aerobic bacteria have verified the endosymbiotic theory, which explains the origin of mitochondria and chloroplasts from bacteria.

These plant communities cover approximately 9. 4 percent of the Earth's surface ( or 30 percent of total land area ), though they once covered much more ( about 50 percent of total land area ), in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the biosphere.

These organisms may help to show:

These organisms are now used for several purposes, and are particularly important in producing large amounts of pure human proteins for use in medicine.

These ( and other ) critics have questioned how natural selection operating on individual organisms can lead to the evolution of planetary-scale homeostasis.

These pathways occur within all living organisms in some form:

These nutrients are typically found in edible plants, especially colorful fruits and vegetables, but also other organisms including seafood, algae, and fungi.

These proteins are crucial for cellular motility of single celled organisms and the sperm of many multicellular organisms which reproduce sexually.

These are sophisticated ways of reducing the variation displayed by organisms to a manageable level.

These small particles or organisms gain entry when the shell valves are open for feeding or respiration.

These function, typically in higher organisms, as hormones and signaling molecules.

These base pairs have a higher thermal stability ( melting point, see also DNA-DNA hybridization ) than adenine-thymine, a property that might convey, among organisms living in high-temperature environments, a selective advantage on variants enriched in GC content.

These personal and social goals often overshadow the goals of intellectual clarity, and spiritual transcendence.

These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids.

These villages, called pueblos by Spanish settlers, were often only accessible by rope or through rock climbing.

These surfacing stones were often placed in distinctive patterns.

These modifications are often essential for the function or regulation of a protein ; for example, the carboxylation of glutamate allows for better binding of calcium cations, and the hydroxylation of proline is critical for maintaining connective tissues.

These measured positions are then compared with those calculated by the laws of celestial mechanics: an assembly of calculated positions is often referred to as an ephemeris, in which distances are commonly calculated in astronomical units.

These and most other cities and large towns are now connected with asphalt-paved roads, while smaller towns are often connected by dirt roads, which may require a four-wheel-drive vehicle.

These Abrasax-stones often bear Hebraic names of God: Iao, Sabaoth, Adonai, Eloai.

These guitars are most commonly used by swing and jazz players and often incorporate electronics in the form of a pickup.

These edicts often pertained to matters such as the regulation of the public markets, or what we might call " economic regulation ".

These assist in flotation, together with the vacuoles in the ectoplasm, which often contain zooxanthellae.

These effects, often several of them at a time, made it very difficult for World War II era aircraft to reach speeds much beyond 800 km / h ( 500 mph ).

These include serotonin-dopamine antagonists ( see dopamine antagonist and serotonin antagonist ), multi-acting receptor-targeted antipsychotics ( MARTA, those targeting several systems ), and dopamine partial agonists, which are often categorized as atypicals.

These two values are often interpreted as binary digits and are usually denoted by the numerical digits 0 and 1.

These BBSes often had multiple modems and phone lines, allowing several users to upload and download files at once.

These instruments had varying numbers of strings, though often including some form of drone.

; Presiding Bishop or President Bishop: These titles are often used for the head of a national Anglican church, but the title is not usually associated with a particular episcopal see like the title of a primate.
