They kill and destroy, retard or prevent reproduction and growth, impair and damage values, and disrupt uses.

“ They may produce global epidemics and impair the health of future generations .” He then stated that, in recognition of these dangers, the United States had decided to destroy its entire stockpile of biological agents and confine its future biological research program to defensive measures, such as vaccines and field detectors.

They are not always painful, but can cause lameness and impair mobility.

They are also abundant components of the peptidoglycan cell walls of bacteria, and-serine may act as a neurotransmitter in the brain.

They can be exported in the apoptotic bodies that pinch off from the surface of the dying cell and the fact that they are engulfed by phagocytes prevents the initiation of a host response.

They usually get the heat from the exhaust of a generator or fuel cell.

They send these signals by means of an axon, which is a thin protoplasmic fiber that extends from the cell body and projects, usually with numerous branches, to other areas, sometimes nearby, sometimes in distant parts of the brain or body.

* Mannans: They form microfibrils in the cell walls of a number of marine green algae including those from the genera, Codium, Dasycladus, and Acetabularia as well as in the walls of some red algae, like Porphyra and Bangia.

* Sulfonated polysaccharides: They occur in the cell walls of most algae ; those common in red algae include agarose, carrageenan, porphyran, furcelleran and funoran.

They prevent these substances from becoming incorporated in to DNA during the " S " phase ( of the cell cycle ), stopping normal development and division.

They prevent the cell from entering the G1 phase ( the start of DNA replication ) and the replication of DNA ( the S phase ).

They are released from bacteria in vivo or after decomposition of the cell.

They are effectively solidified as an ultrahigh density deuterium lump ( Pycnodeuterium ) inside each octahedral space within the unit cell of the palladium host lattice.

They also produce enzymes which break down lignin, which allows to them access to both cell contents and to the nitrogen in the lignin.

They are principally sorting organelles where many ligands dissociate from their receptors in the acid pH of the lumen, and from which many of the receptors recycle to the cell surface ( via tubules ).

They are generally regarded as the principal hydrolytic compartment of the cell.

They are used to power fuel cell vehicles, including automobiles, buses, forklifts, airplanes, boats, motorcycles and submarines.

They can reach a fuel-to-electricity efficiency of 50 %, considerably higher than the 37-42 % efficiency of a phosphoric acid fuel cell plant.

They often promote cell differentiation and maturation, which varies between growth factors.

They determined this from the amount of radioactive material remaining outside of the cell.

They are present on all membranes of cell ( plasma membrane ) and intracellular organelles ( nucleus, mitochondria, endoplasmic reticulum, golgi apparatus and so on ).

They accomplish this by being exposed to the extracellular face of the cell membrane after the inactivation of flippases which place them exclusively on the cytosolic side and the activation of scramblases, which scramble the orientation of the phospholipids.

They can be described as the stomach of the cell.

They are frequently nicknamed " suicide-bags " or " suicide-sacs " by cell biologists due to their autolysis.

They are used for the digestion of macromolecules from phagocytosis ( ingestion of other dying cells or larger extracellular material, like foreign invading microbes ), endocytosis ( where receptor proteins are recycled from the cell surface ), and autophagy ( where in old or unneeded organelles or proteins, or microbes that have invaded the cytoplasm are delivered to the lysosome ).

They vary in number and location according to cell type.

They are also involved in determination of cell division site based on the geometry and polarity of the cells.

They differ from other related families by often being pachycauline ( i. e. with a thickened trunk, usually wider at the base, which has a water storage function ), by usually having succulent leaves, and by possessing a trimerous flower with a superior ovary and seeds with an aryl.

They may not administer Penance ( Reconciliation ), Anointing of the Sick ( Extreme Unction ), or function as an ordained celebrant or concelebrant of the Mass ( by virtue of their office and their training and institution, they may act, if the need arises, as altar servers, lectors, ushers, porters, or Eucharistic ministers of the Cup, and if need be, the Host ).

They cover all of the available bone surface and function as a barrier for certain ions.

They noted that even traits that spread through diffusion often were given different meanings and function from one society to another.

They express how sensitive that function is to small changes ( or small errors ) in its arguments.

They can function over pressure ranges of 10 < sup >− 10 </ sup > to 10 < sup >− 2 </ sup > mbar.

They need to be analyzed and criticized in all their manifestations ; the function of both logical and axiological oppositions must be studied in all discourses to provide meaning and values.

They generally regard financial markets that function for the financial system as an efficient mechanism.

They wish to allow the market to function smoothly and give it the freedom to change and develop.

They may function as forums for developing competence and are often the local units of a national employer's organization.

They mainly functioned as local government authorities at the county level, as well as having a pre-trial judicial function for serious criminal cases.

They showed that, in growth, protein has no function, while DNA has some function.

* They function as other lexical categories — usually nouns — within the clauses that contain them, for example by serving as the subject of another verb.

( In 3D graphics, lights function similarly to real-world lights: They cause illumination, cast shadows, and create specular highlights.

They further identified members of a group that had been marginalized ; women who had been rejected by most of society had an inside view of an exclusive group of people that took a high amount of knowledge to function in.

They continued, however, to function in all respects ( rule, clothing and policy ) as an autonomous branch of the Teutonic Order, headed by their own Master ( himself de jure subject to the Teutonic Order's Grand Master ).

They are accountable to the top management for their department's function.

They lack membrane-bound organelles, and can function and reproduce as individual cells, but often aggregate in multicellular colonies.

They may span multiple lines and function like here documents in shells, Perl and Ruby.

They are involved in the catabolism of very long chain fatty acids, branched chain fatty acids, D-amino acids, polyamines, and biosynthesis of plasmalogens, i. e. ether phospholipids critical for the normal function of mammalian brains and lungs.

They both address “ situations that tend to develop in the bosom of the family .” Both authors, through their plays, reflect a patriarchal society in which the father-son relationship is essential to proper function and development of the household.

They also function to protect the burrows from flooding.

They also contain air chambers that may function to protect the burrow from flooding and a listening post for predators.
