Some religions distinguish between sexual activities that are practiced for biological reproduction ( sometimes allowed only when in formal marital status and at a certain age ), and other activities practiced for sexual pleasure, as immoral.

Some sequences may have no biological function for the organism, such as endogenous retroviruses.

Some introns appear to have significant biological function, possibly through ribozyme functionality that may regulate tRNA and rRNA activity as well as protein-coding gene expression, evident in hosts that have become dependent on such introns over long periods of time ; for example, the trnL-intron is found in all green plants and appears to have been vertically inherited for several billions of years, including more than a billion years within chloroplasts and an additional 2 – 3 billion years prior in the cyanobacterial ancestors of chloroplasts.

Some features of the human circadian biological clock

During his time as professor at Copenhagen University he spent some time working abroad, and in 1934 submitted a thesis entitled Nogle Undersøgelser over Sterinernes Biologiske Betydning ( Some investigations on the biological significance of the sterines ) to Copenhagen University, and received the degree of Ph. D. in biochemistry.

Some genera – such as Larinus whose larval food is flowerheads – have many species especially adapted to particular knapweeds or starthistle and are used in biological control too.

Some agents have been shown to be much more toxic or infectious to experimental animals when exposed to aerosols of optimum particle size than by the natural portal.

Some may suggest that it is probably advisable to use mouthwash at least an hour after brushing with toothpaste when the toothpaste contains sodium lauryl sulfate, since the anionic compounds in the SLS toothpaste can deactivate cationic agents present in the mouthrinse.

Some members provide products including cooking oils, lettuce, sunflower seeds, artichokes, sweetening agents, coffee substitutes and teas.

Some of these astrologers have proposed conventional causal agents such as electromagnetism and gravity.

Some newer agents do not directly interfere with DNA.

Some tumors can be destroyed by sufficiently high doses of chemotherapeutic agents.

Some examples include: to develop reasoning about perennial questions, to master the methods of scientific inquiry, to cultivate the intellect, to create positive change agents, or simply to teach pupils how to think.

Some days after that meeting, the delegation was approached by three French agents ( at first identified as " X ", " Y ", and " Z " in published papers, leading the controversy to be called the " XYZ Affair ") who demanded substantial bribes from the commissioners before negotiations could continue.

Some models in econophysics have shown that when agents are allowed to interact locally in a free market ( i. e. their decisions depend not only on utility and purchasing power, but also on their peers ' decisions ), prices can become unstable and diverge from the equilibrium, often in an abrupt manner.

Some time later, Jet Jaguar is completed but the trio of inventors are knocked unconscious by the returning seatopian agents.

Some infectious agents may be spread as a result of contact with a contaminated, inanimate object ( known as a fomite ), such as a coin passed from one person to another, while other diseases penetrate the skin directly.

Some individuals develop natural serum antibodies to the surface polysaccharides of some agents although they have had little or no contact with the agent, these natural antibodies confer specific protection to adults and are passively transmitted to newborns.

Some alkylating agents such as N-Nitrosamines may also require the catalytic reaction of cytochrome-P450 for the formation of a reactive alkyl cation.

Some alkylating agents may produce crosslinking of DNA.

Some nerve agents are readily vaporized or aerosolized and the primary portal of entry into the body is the respiratory system.

Some of these agents included exiled communists and Socialist party members, labor activists, anti-Nazi prisoners-of-war, and German and Jewish refugees.

Some Viral Hemorrhagic Fever causing agents like Lassa fever virus, Rift Valley fever, Marburg virus, Ebola virus and Bolivian hemorrhagic fever are highly contagious and deadly diseases, with the theoretical potential to become pandemics.

Some thickening agents are gelling agents, forming a gel.

Some of these enzymes are used in molecular biology ( for example, heat-stable DNA polymerases for PCR ), and in washing agents.

Some of the double agents were informed in radio messages from Germany after the invasion that they had been awarded the Iron Cross.

Some directory operations ( including < tt > unlink </ tt >( 2 )) are not synchronous on ReiserFS, which can result in data corruption with applications relying heavily on file-based locks ( such as mail transfer agents qmail and Postfix ) if the machine halts before it has synchronized the disk.
